This is easily perceived as a clear pitch. -- At 20 kHz (highest audible frequency): -Period = 1/20000 = 0.00005 seconds (0.05ms). In 45ms, you get 45/0.05 = 900 cycles. This is far more than needed for pitch perception, but such high frequencies are often perceived as less "musical." - -**Conclusion:** Lower frequencies (e.g., 20 Hz) are barely perceivable as distinct pitches in 45ms because they complete less than one cycle. Higher frequencies (e.g., 100 Hz and above) are more likely to be perceived as notes. The exact number of cycles needed for pitch perception varies, but research suggests 2–4 cycles are often sufficient for mid-range frequencies. - -**How Many Notes Can Fit in the 20 Hz to 20 kHz Range?** - -The range of 20 Hz to 20 kHz spans the entire audible spectrum. In musical terms, this corresponds to all possible notes in the Western 12-tone equal temperament system (and beyond). Let’s estimate: -- The lowest musical note is around A0 (27.5 Hz), and the highest commonly used note is C8 (4186 Hz), though higher frequencies up to 20 kHz could theoretically be perceived as pitches. -- In equal temperament, each octave doubles the frequency, and there are 12 semitones per octave. The number of semitones between two frequencies -$f_1$ and $f_2$ is given by: - -$n = 12 \cdot \log_2\left(\frac{f_2}{f_1}\right)$ - -For 27.5 Hz to 4186 Hz: - -$n = 12 \cdot \log_2\left(\frac{4186}{27.5}\right)$ $\approx 12 \cdot \log_2(152.22)$ $\approx 12 \cdot 7.25 \approx 87 \text{ semitones}$ - -This corresponds to about 7 octaves (since 12 semitones = 1 octave), covering roughly 88 notes (similar to a standard piano). -- Extending to 20 kHz: - -$n = 12 \cdot \log_2\left(\frac{20000}{27.5}\right)$ $\approx 12 \cdot \log_2(727.27)$ $\approx 12 \cdot 9.5 \approx 114 \text{ semitones}$ - -This adds another ~27 semitones, totaling around 115 distinct pitches in the audible range. - -However, in a 45ms frame, not all these notes can be distinctly perceived if played simultaneously due to: -- Masking: When multiple frequencies are played at once, louder or lower frequencies can mask higher or quieter ones, reducing the number of distinguishable notes. -- Auditory resolution: The human ear can distinguish individual frequencies if they are sufficiently separated (e.g., by a critical bandwidth, roughly 1/3 octave in mid-frequencies). In polyphonic sound, the ear can typically resolve 5–10 simultaneous notes, depending on their frequency spacing and amplitude. -**Conclusion:** Theoretically, the 20 Hz to 20 kHz range contains ~115 distinct musical notes (semitones). In a 45ms frame, you could play all of them simultaneously, but the ear would only distinguish a subset (likely 5–10 notes) due to masking and perceptual limits. - -**Does the Number of Notes Make a Difference?** - -Yes, the number of notes played simultaneously in a 45ms frame affects perception: -- Single note: If only one note (e.g., 440 Hz, A4) is played, it’s easily perceived as a pitch in 45ms (~20 cycles). -- Few notes (e.g., a chord): A chord with 3–5 notes (e.g., C-E-G) can be distinguished if the frequencies are spaced appropriately (e.g., in different critical bands). In 45ms, the ear can identify the chord’s quality (major/minor) if the notes are clear. -- Many notes (e.g., 10+): As more notes are added, they start to blend into a complex timbre or noise-like sound. The ear struggles to pick out individual pitches due to masking and cognitive limits. For example, a cluster chord (e.g., all 12 semitones in an octave) in 45ms might sound more like a dense texture than distinct notes. -The amplitude and timbre of each note also matter. Notes with similar frequencies or overlapping harmonics interfere more, reducing clarity. For instance, two notes an octave apart (e.g., 440 Hz and 880 Hz) are easier to distinguish than two notes a semitone apart (e.g., 440 Hz and 466 Hz). -**Conclusion:** The number of notes matters because of auditory masking and perceptual limits. In 45ms, 1–5 notes are clearly distinguishable; beyond that, the sound becomes increasingly complex or noisy. - -**What If There Is No Tempo?** - -Tempo refers to the rate at which musical events (e.g., notes or beats) occur over time, typically measured in beats per minute (BPM). - -- Notes played simultaneously: If all notes in the 45ms frame start and end at the same time (like a chord), tempo is irrelevant because there’s no rhythmic sequence. The analysis above (about masking and perceptual limits) applies. -- Notes played sequentially: If you mean notes played one after another within 45ms, “no tempo” might imply an arbitrary or extremely fast sequence. Let’s explore this: - - In 45ms, there’s very little time to play multiple notes sequentially. For example, if each note lasts 10ms, you could fit ~4 notes (45/10 ≈ 4.5). However, at such short durations, the notes blur together, and the ear may not perceive them as distinct events. - - Without a defined tempo, the sequence lacks rhythmic structure, but the ear still processes the frequencies. If the notes are too short (e.g., <10ms), they may sound like clicks or a single complex sound rather than a melody. -In either case, the absence of tempo doesn’t change the fundamental limits of pitch perception in 45ms. It only affects how we interpret the sound’s rhythmic or sequential structure. Without tempo, the sound might feel “static” (if simultaneous) or “chaotic” (if sequential). -**Conclusion:** No tempo means the notes are either simultaneous (like a chord) or arbitrarily sequenced. In 45ms, simultaneous notes are limited by masking (5–10 distinguishable), and sequential notes are limited by duration (2–4 if very short), often blending into a single sound. - -TL,DR: - -**How many musical notes can be heard in a 45ms frame?** - -Theoretically, you could play all ~115 audible semitones (20 Hz to 20 kHz) in a 45ms frame, but the human ear can only distinguish ~5–10 simultaneous notes due to masking and auditory resolution. Lower frequencies (e.g., 20 Hz) are barely perceptible in 45ms (<1 cycle), while higher frequencies (e.g., 100 Hz and above) are clearer. - -**Does the 20 Hz to 20 kHz range fit?** - -Yes, the entire 20 Hz to 20 kHz range fits, as it encompasses all audible frequencies. However, in 45ms frame, not all frequencies are equally perceivable as distinct musical notes. - -**Does it make a difference how many notes?** - -Yes, more notes increase complexity. 1–5 notes are clearly distinguishable; beyond that, the sound becomes dense or noisy due to masking. - -**What if there is no tempo?** - -Without tempo, notes are either simultaneous (chord-like, limited to ~5–10 distinguishable pitches) or sequential (2–4 very short notes, often blending). The absence of tempo doesn’t change the perceptual limits in 45ms. - - -## Sequential approach - -In a sequential approach within a 45ms frame, the shortest duration for musical notes to be coherently perceived as distinct pitches by the human auditory system is approximately 5–10 ms for mid-to-high frequencies (e.g., 200–2000 Hz). This is based on the need for 2–4 cycles of a sound wave for pitch recognition and the auditory system's temporal resolution of ~2–5 ms for distinguishing sequential events. - -**Key Points:** - -- Minimum note duration: - - Mid-to-high frequencies (e.g., 440 Hz, A4): ~5 ms (2 cycles) to 10 ms (4 cycles) ensures clear pitch perception. - -Lower frequencies (e.g., 50 Hz): ~20–40 ms is needed, limiting the sequence to 1–2 notes in 45ms. - -- Number of notes in 45ms: - - Without gaps: ~4–9 notes (5–10 ms each). - -With small gaps (e.g., 2 ms for separation): ~3–6 notes (7–12 ms per note + gap). - -- Perceptual limits: Notes shorter than 5 ms may sound like clicks or a rapid sweep rather than distinct pitches, especially for lower frequencies. Cognitive processing limits sequences to 6–8 notes per second (125–167 ms per note), so 5–6 notes in 45ms is a practical maximum for melodic clarity. - -- Timbre and context: Sharp attack sounds (e.g., piano) enhance separation, allowing shorter notes (closer to 5 ms) to remain distinct compared to smooth sounds. - - -TL;DR: -The shortest note duration for coherent perception in a sequential approach is ~5–10 ms for mid-to-high frequencies, allowing 4–9 notes without gaps or 3–6 notes with small gaps (2 ms) in a 45ms frame. Lower frequencies require longer durations (20–40 ms), reducing the count to 1–2 notes. - -## Transposed convolution - -Often referred to as deconvolution (though not technically accurate), is a technique used in convolutional neural networks (CNNs) to upsample feature maps. While standard convolution reduces the spatial dimensions of the input (e.g., an image), transposed convolution increases them, effectively performing the opposite operation in terms of dimensionality. - -### Pixel-Level Explanation: -1. **Standard Convolution**: - - Takes an input feature map (e.g., an image) and applies a kernel (filter) to extract features. - - The kernel slides across the input with a defined **stride** (step size), computing dot products between the kernel and local regions of the input. - - **Padding** can be added to preserve the spatial dimensions of the input. - - The result is a smaller feature map (unless padding and stride are carefully chosen). - -2. **Transposed Convolution**: - - Instead of reducing dimensions, transposed convolution increases them by "reversing" the convolution process in terms of shape. - - It works by inserting zeros between the input pixels (a process known as **upsampling** or **dilation** of the input). - - The kernel then slides over this expanded input, producing an output feature map larger than the original input. - - The **stride** in transposed convolution controls the spacing between the input pixels in the upsampled input. - - **Padding** in transposed convolution is used to control the final output size, often by removing padding from the edges. - -### Mathematical Insight: -For a standard convolution, the output size is calculated as: - -$$\text{Output Size} = \frac{\text{Input Size} - \text{Kernel Size} + 2 \times \text{Padding}}{\text{Stride}} + 1$$ - -For transposed convolution, the output size is calculated as: - -$$\text{Output Size} = (\text{Input Size} - 1) \times \text{Stride} + \text{Kernel Size} - 2 \times \text{Padding} + \text{Output Padding}$$ - -### Key Differences: -- **Standard Convolution**: Reduces spatial dimensions, extracting features. -- **Transposed Convolution**: Increases spatial dimensions, used for upsampling. -- **Not a True Inverse**: While transposed convolution can reverse the spatial dimensions of a convolution, it does not reverse the actual values—some information is lost during the standard convolution process. - -### Applications: -- **Image Generation**: Used in Generative Adversarial Networks (GANs) to generate high-resolution images from low-dimensional noise. -- **Image Segmentation**: Helps in upsampling feature maps to match the original image size for pixel-wise predictions. -- **Autoencoders**: Used in the decoder part to reconstruct the input from a compressed representation. - -### Example: -Given a 2x2 input matrix: -``` -0 & 1 -2 & 3 -``` - -Using a 2x2 kernel and stride of 1 with no padding, transposed convolution can produce a 3x3 output: - -``` -0 & 0 & 1 -0 & 4 & 6 -4 & 12 & 9 - ``` -This output is formed by broadcasting each input pixel through the kernel, effectively "expanding" the input. - -## **Deep dive** - -> "The kernel slides across the input with a defined stride (step size), computing dot products between the kernel and local regions of the input." - -This is the core mechanism of a **convolution operation**, which is fundamental in **Convolutional Neural Networks (CNNs)**, especially for image processing. - ---- - -### Step-by-Step Breakdown - -#### 1. **Input and Kernel (Filter)** - -- **Input**: Think of this as a 2D grid (e.g., a grayscale image), or a 3D volume (e.g., a color image with height × width × channels like RGB). - - Example (2D grayscale image): - ``` - Input: - [ 1 2 3 4 ] - [ 5 6 7 8 ] - [ 9 10 11 12 ] - [13 14 15 16 ] - ``` - -- **Kernel (Filter)**: A smaller matrix (e.g., 2x2 or 3x3) that acts as a feature detector. - - Example (2x2 kernel): - ``` - Kernel: - [ 0 1 ] - [ 2 3 ] - ``` - ---- - -#### 2. **Sliding the Kernel (Stride)** - -- **Stride** is the number of pixels the kernel moves (steps) after each operation. - -- With **stride = 1**, the kernel moves one pixel at a time (horizontally and vertically). - - Example of positions where the kernel slides over the input (for 2x2 kernel and 4x4 input with stride = 1): - - - Top-left: covers top-left 2x2 region - - Move right: covers top-middle 2x2 region - - Continue until the end of the row - - Then move down one row and repeat - ---- - -#### 3. **Dot Product at Each Position** - -At each position, the kernel is **multiplied element-wise** with the input region it’s covering, and then summed up. - -Let’s do this manually: - -**First Position (Top-left):** -``` -Input region: -[ 1 2 ] -[ 5 6 ] - -Kernel: -[ 0 1 ] -[ 2 3 ] - -Element-wise multiplication: -(1×0) + (2×1) + (5×2) + (6×3) = 0 + 2 + 10 + 18 = 30 -``` - -This gives one value in the output feature map. - -Repeat this for every possible position the kernel slides to. - ---- - -#### 4. **Resulting Feature Map** - -All the dot products are stacked together into a new 2D matrix: the **feature map**. - -If input is 4×4 and kernel is 2×2 with stride = 1, the output feature map will be: -``` -Output (Feature Map): -[ 30 36 42 ] -[ 84 90 96 ] -[138 144 150 ] -``` - -This feature map highlights where the kernel (pattern) is most present in the original image. - ---- - -### Visual Summary -``` -| Step | Description -|------| -| 1 | Select a small kernel (e.g., 3x3) -| 2 | Place it at the top-left of the input image -| 3 | Multiply each input pixel with the corresponding kernel value, sum them → dot product -| 4 | Move kernel by `stride` pixels to the right -| 5 | When reaching the end of a row, move down by `stride` rows -| 6 | Repeat until kernel has covered the entire image -| 7 | Result is a new, smaller matrix: the **feature map** -``` ---- - -### Key Concepts - -- **Local Receptive Field**: The small region of the input that the kernel covers at each step. -- **Weight Sharing**: The same kernel is used across the entire image → fewer parameters than fully connected layers. -- **Feature Detection**: Different kernels detect different features (edges, corners, textures, etc.) - ---- - -### Why Is This Useful? - -- **Spatial Hierarchy**: CNNs learn increasingly complex features (edges → shapes → objects). -- **Translation Invariance**: Similar patterns are detected regardless of position. -- **Efficiency**: Uses weight sharing and local connectivity to reduce parameters. - ---- - -### Try It Yourself (Pseudocode) - -```python -def apply_convolution(input, kernel, stride): - output = [] - for i in range(0, input.height - kernel.height + 1, stride): - row = [] - for -``` -## In detail - -Let's clarify and expand. - ---- - -### The Input is 4x4 (16 pixels total) - -Your example input: -``` -[ 1 2 3 4 ] -[ 5 6 7 8 ] -[ 9 10 11 12 ] -[13 14 15 16 ] -``` -This is a 4×4 matrix — that’s 16 pixels total. - ---- - -### The Kernel is 2x2 (4 pixels) - -Your kernel: -``` -[ 0 1 ] -[ 2 3 ] -``` -This is a 2×2 filter — 4 weights total. - ---- - -## How Does Stride = 1 Work? - -### Common Convention: -- The kernel **slides (moves) from left to right**, and **after finishing a row, moves down by one row**. -- So the direction is: - - **→ (left to right)** per row - - **↓ (top to bottom)** between rows - - ---- - -## Let's Step Through the Example - -Original input: -``` -Row 0: [ 1 2 3 4 ] -Row 1: [ 5 6 7 8 ] -Row 2: [ 9 10 11 12 ] -Row 3: [13 14 15 16 ] -``` - -### First Kernel Position (Top-left): -Covers: -``` -[1 2] -[5 6] -``` - -### Then Stride = 1 → Move Right: -Covers: -``` -[2 3] -[6 7] -``` - -### Then Move Right Again: -Covers: -``` -[3 4] -[7 8] -``` - -### Then Move Down to Next Row: -Now we start again from the left of the next row: -Covers: -``` -[5 6] -[9 10] -``` - -And so on... - ---- - -## Output Feature Map Coordinates - -If you label each top-left pixel of the kernel’s position as `(i, j)` in the input, the kernel visits: -- `(0,0)` → top-left -- `(0,1)` → move right -- `(0,2)` → move right again -- `(1,0)` → move down -- `(1,1)` → etc. - -This is how the kernel "scans" the image. - ---- - -## Output Feature Map Size - -Using the formula: - -$$ -\text{Output size} = \frac{\text{Input size} - \text{Kernel size}}{\text{Stride}} + 1 -$$ - -So for: -- Input: `4x4` -- Kernel: `2x2` -- Stride: `1` - -$$ -\text{Output size} = \frac{4 - 2}{1} + 1 = 3 \Rightarrow \text{Output is } 3 \times 3 -$$ - ---- - -## Summary - -> "If we were looking at pixels 1,2,5,6 by the kernel and then it strides 1, would we be looking at pixels 3,4,7,8?" - - -- First: kernel covers: - ``` - [1 2] - [5 6] - ``` -- After stride = 1 (move right by one): - ``` - [2 3] - [6 7] - ``` -- Next: - ``` - [3 4] - [7 8] - ``` - - ---- - -## What is Padding? - -**Padding** is a technique used in convolutional operations to **add extra pixels around the borders of the input image or feature map**, before applying the convolution. - -### Purpose of Padding: -- To **preserve spatial dimensions** (i.e., keep the output feature map the same size as the input). -- To **allow the kernel to capture information from the edges** of the input (without padding, edge pixels are seen by fewer filters, which can lead to loss of information). - ---- - -## Types of Padding - -There are two main types: - -### 1. **Zero Padding (Most Common)** -- Adds zeros around the borders. -- Most widely used in CNNs. -- Also called "constant padding". - -### 2. **Other Types (Less Common)** -- **Replication Padding**: Repeats the edge values. -- **Reflection Padding**: Reflects the input values at the border. -- **Circular Padding**: Treats the input as circular. - ---- - -## How Padding Affects Output Size - -Recall the **output size formula** of a convolution: - -$$\text{Output Size} = \frac{\text{Input Size} + 2 \times \text{Padding} - \text{Kernel Size}}{\text{Stride}} + 1$$ - -Where: -- `Input Size` = spatial dimension (height or width) of the input -- `Padding` = number of pixels added to each side -- `Kernel Size` = size of the convolution filter -- `Stride` = step size - ---- - -## Example with Padding - -Let’s use: -- Input size: `4x4` -- Kernel size: `2x2` -- Stride: `1` -- Padding: `0` (no padding) - -Output size: - -$$\frac{4 - 2}{1} + 1 = 3 \Rightarrow 3x3 \text{ output}$$ - -Now, **add padding = 1**: - -Input effectively becomes `6x6` (4 + 2×1), so: - -$$\frac{4 + 2×1 - 2}{1} + 1 = \frac{4}{1} + 1 = 5 \Rightarrow 5x5 \text{ output}$$ - -If you want the **same size as input**, you choose padding so that: - -$$\text{Output Size} = \text{Input Size}$$ - -Let’s solve for that: - -$$\text{Input Size} = \frac{\text{Input Size} + 2 \times \text{Padding} - \text{Kernel Size}}{\text{Stride}} + 1$$ - -Let’s simplify this for **stride = 1**: - -$$\text{Padding} = \frac{\text{Kernel Size} - 1}{2}$$ - -So: -- For kernel size 3×3 → padding = 1 -- For kernel size 5×5 → padding = 2 -- For kernel size 2×2 → padding = 0.5 (not possible, so not used for stride 1) - ---- - -## Visual Example - -Without padding: -``` -Input (4x4): -[ 1 2 3 4 ] -[ 5 6 7 8 ] -[ 9 10 11 12 ] -[13 14 15 16 ] -``` - -After adding **padding = 1** (zero-padding): -``` -[0 0 0 0 0 0] -[0 1 2 3 4 0] -[0 5 6 7 8 0] -[0 9 10 11 12 0] -[0 13 14 15 16 0] -[0 0 0 0 0 0] -``` - -Now we can apply the kernel at all original positions **and** at the edges. - ---- - -## Why Is Padding Important? - -1. **Preserves Resolution**: Without padding, each convolution shrinks the image → deep networks would lose spatial size too quickly. -2. **Edge Information**: Without padding, edge pixels are involved in fewer convolutions → less information learned from them. -3. **Better Performance**: Padding is often used to maintain resolution while learning deeper representations. - ---- - -## Example in Practice (Using PyTorch-like Syntax) - -```python -import torch -import torch.nn as nn - -# Input: batch of 1 grayscale 4x4 image -input = torch.tensor -``` - -## Here’s a simplified example using real pixel values to generate a feature map: - -For a convolutional neural network (CNN) processes grayscale images by applying convolutional kernels (filters) to extract meaningful features. - -1. **Input Image (Grayscale)**: Consider a 5x5 grayscale image with pixel values normalized between 0 and 1: -$$ -\begin{bmatrix} -0.1 & 0.2 & 0.3 & 0.4 & 0.5 \\ -0.6 & 0.7 & 0.8 & 0.9 & 1.0 \\ -0.2 & 0.3 & 0.4 & 0.5 & 0.6 \\ -0.7 & 0.8 & 0.9 & 1.0 & 0.1 \\ -0.3 & 0.4 & 0.5 & 0.6 & 0.7 \\ -\end{bmatrix} -$$ - -2. **Convolutional Kernel (Filter)**: Use a 3x3 kernel designed for edge detection: - -$$ -\begin{bmatrix} --1 & -1 & -1 \\ --1 & 8 & -1 \\ --1 & -1 & -1 \\ -\end{bmatrix} -$$ - -3. **Convolution Operation**: - - Slide the kernel over the input image with a stride of 1. - - Compute the dot product between the kernel and the corresponding section of the image. - - For the top-left 3x3 section of the image: - - -$$ -\begin{bmatrix} -0.1 & 0.2 & 0.3 \\ -0.6 & 0.7 & 0.8 \\ -0.2 & 0.3 & 0.4 -\end{bmatrix} -\cdot -\begin{bmatrix} --1 & -1 & -1 \\ --1 & 8 & -1 \\ --1 & -1 & -1 -\end{bmatrix} -= (0.1 \cdot -1) + (0.2 \cdot -1) + (0.3 \cdot -1) + (0.6 \cdot -1) + (0.7 \cdot 8) + (0.8 \cdot -1) + (0.2 \cdot -1) + (0.3 \cdot -1) + (0.4 \cdot -1) -$$ - -$$ -= -0.1 - 0.2 - 0.3 - 0.6 + 5.6 - 0.8 - 0.2 - 0.3 - 0.4 = 2.7 -$$ - -4. **Feature Map**: Repeat the operation across the entire image to generate a feature map. For example, the resulting feature map might look like: - -$$ -\begin{bmatrix} - 2.7 & 3.0 & 3.3 \\ - 3.6 & 4.0 & 4.4 \\ - 4.5 & 5.0 & 5.5 -\end{bmatrix} -$$ - -This feature map highlights areas of the image where edges or abrupt changes in intensity occur, which the CNN can use to detect patterns relevant to the task, such as object boundaries. During training, the CNN learns optimal filter values to maximize the detection of task-relevant features. - -## Depth estimation** or **Stereo vision** - -Where disparity (often the inverse of depth) is predicted, and losses are crafted to be **invariant to scale and shift**—which is crucial in many monocular depth prediction settings where absolute depth cannot be recovered. - -Let’s break this down into key ideas: - ---- - -## **1. Prediction in Disparity Space** - -* **Disparity**: In stereo vision, disparity is the difference in the horizontal position of a pixel in the left and right images. It’s inversely related to depth: - - $$ - d = \frac{f \cdot B}{Z} - $$ - - where: - - * $d$: disparity - * $f$: focal length - * $B$: baseline (distance between cameras) - * $Z$: depth - -* **Inverse Depth Up to Scale and Shift**: In monocular depth estimation, the predicted inverse depth (disparity) is **only accurate up to a global scale and shift**, because without stereo or known camera motion, absolute depth can’t be recovered. - ---- - -## **2. Scale- and Shift-Invariant Dense Losses** - -These are loss functions that are: - -* **Dense**: Evaluate every pixel (not sparse or point-wise) -* **Invariant to scale and shift**: So that predicted depth maps don’t have to match the absolute depth values exactly — only the **structure** of the scene needs to be correct (e.g., depth relationships between pixels) - -### Common examples: - -#### a) **Scale-and-Shift-Invariant MSE** - -From *"Dense Depth Estimation Without Dense Ground Truth" (Watson et al., CVPR 2019)*: - -$$ -\min_{\alpha, \beta} \| \alpha \hat{d} + \beta - d \|^2 -$$ - -* Here, $\hat{d}$ is the predicted disparity/depth -* $d$ is ground truth -* $\alpha$, $\beta$ are optimal scale and shift to align the prediction with ground truth before computing the error - -#### b) **Gradient and SSIM Losses** - -Losses based on: - -* **Image gradients** (to preserve edges and structure) -* **SSIM (Structural Similarity Index)**, which compares local luminance, contrast, and structure - -These help the model focus on *relative* depth structure rather than exact values. - ---- - -## **Use Case Summary** - -This approach is most useful when: - -* Training with **monocular images** (where scale is ambiguous) -* Evaluating or supervising using **depth maps or disparities** that might be scaled or shifted relative to the ground truth - ---- - -**Geometry of disparity and inverse depth** ---- - -## **Q: Can disparity be computed using an image split in half (left/right parts), or must it be from two different cameras?** - -### Short Answer: - -**Disparity estimation assumes two views of the same scene from **different perspectives** (i.e., different camera centers). Just splitting a single image in half does *not* give you valid disparity — unless you simulate the geometric effect of a second viewpoint.** - ---- - -## Let’s understand this mathematically. - -### 1. **What is Disparity?** - -Disparity is defined as: - -$$ -d(u, v) = x_L(u, v) - x_R(u, v) -$$ - -Where: - -* $x_L(u, v)$: horizontal coordinate in the left image -* $x_R(u, v)$: matching horizontal coordinate in the right image (same 3D point) - -In **pinhole camera model**, disparity relates to depth via: - -$$ -Z = \frac{f \cdot B}{d} -\quad\Leftrightarrow\quad -d = \frac{f \cdot B}{Z} -$$ - -Where: - -* $Z$: depth (distance from camera to point in 3D) -* $f$: focal length -* $B$: baseline (distance between camera centers) -* $d$: disparity - -So, disparity arises *because* two cameras are located at different positions — **parallax** causes the same 3D point to project to different positions in the two images. - ---- - -### 2. **What if I split a single image in half?** - -Let’s suppose you take a single image $I$ and split it into: - -* $I_L$: left half -* $I_R$: right half - -Now you try to compute disparity between $I_L$ and $I_R$. - -#### Why this is **invalid geometrically**: - -There is **no camera motion** between $I_L$ and $I_R$. Both halves are from the **same optical center**. Every pixel was projected through the same pinhole. - -* There’s no *true parallax*. -* There’s no *triangulation* baseline $B$. -* Any difference between $I_L$ and $I_R$ would be **due to scene content variation**, not geometry. - -#### Mathematical contradiction: - -Suppose we try to use disparity formula: - -$$ -Z = \frac{f \cdot B}{d} -$$ - -But since $B = 0$ (no second camera), we get: - -$$ -Z = \frac{f \cdot 0}{d} = 0 -$$ - -Or, you might say $d = 0$ (since pixel positions don’t change), which implies $Z \to \infty$ — again, nonsensical. - ---- - -### 3. **Can we simulate disparity with a synthetic shift?** - -You *can* simulate stereo data from a single image by: - -* Assuming a proxy depth map or plane -* Shifting pixels **as if** they came from another camera - -But this requires: - -* Knowledge of scene depth -* Geometry-based image warping - -In that case, you're synthesizing a **novel view** from a slightly shifted camera pose (i.e., generating stereo). - ---- - -### 4. **Why real stereo or multi-view is needed for disparity?** - -Because the disparity is a **proxy for depth**, and depth arises from the triangulation of multiple rays intersecting in 3D space. Without a baseline $B$, the rays are all the same — there's no triangle to form. - -This also explains why **monocular depth estimation** models: - -* Predict **inverse depth up to scale and shift** -* Must be trained using stereo pairs or known 3D priors to learn geometric cues - ---- - -## Summary: - -| Scenario | Disparity Meaningful? | Why? | -| ------------------------------------- | ------------------------- | --------------------------------------------- | -| Two images from different cameras | Yes | Different viewpoints ⇒ parallax ⇒ depth | -| Image split in half | No | No baseline ⇒ no parallax ⇒ no disparity | -| Synthesized second view from depth | Yes (simulated) | Artificial parallax from known geometry | -| Monocular with learning (no GT depth) | ⚠ Only up to scale/shift | Learned statistical priors, not true geometry | - ---- -Synthesizing a **novel view**—i.e., generating what a scene would look like from a different (virtual) camera viewpoint—is a core problem in **computer vision and graphics**, especially in **view synthesis**, **stereo simulation**, and **NeRF-style rendering**. - -## Main approaches **by input and technique**: - ---- - -## 1. **Depth-based Image Warping** - -**Input**: RGB image + predicted or known depth -**Output**: Synthesized view from a nearby virtual camera - -### Method: - -Use the depth map to **project pixels to 3D**, then re-project to the target camera pose. - -#### Steps: - -1. For each pixel $(u,v)$ , use depth $Z(u,v)$ to compute 3D point in world space: - -$$ -\mathbf{X} = Z(u,v) \cdot K^{-1} [u, v, 1]^T -$$ - - where $K$ is the intrinsic matrix. - -2. Transform the 3D point using relative pose $[R|t]$ to the new view. - -3. Reproject into the target view’s image plane: - -$$ -[u', v', 1]^T \propto K' \cdot (R \cdot \mathbf{X} + t) -$$ - -4. Use **backward warping** (resampling source image at target pixel locations) for image synthesis. - -### Pros: - -* Simple, fast -* Works well for small viewpoint changes - -### Cons: - -* Missing data (occlusions) -* Artifacts near depth edges -* Assumes Lambertian surfaces - ---- - -## 2. **Multi-Plane Images (MPIs)** - -**Input**: Single or few RGB images -**Output**: Novel view synthesized using a stack of semi-transparent depth layers - -### Method: - -1. Discretize scene into fronto-parallel planes at fixed depths -2. Learn per-plane **RGB + alpha (opacity)** layers -3. Composite the layers from back to front to render novel views via **plane sweep** and blending - - **Introduced in**: -*“Stereo Magnification” (Zhou et al., SIGGRAPH 2018)* - -### Pros: - -* Differentiable rendering -* Handles view extrapolation better than depth warping - -### Cons: - -* Requires training -* Limited depth fidelity (discrete planes) - ---- - -## 3. **Neural Rendering / NeRF (Neural Radiance Fields)** - -**Input**: Multiple posed images (monocular or stereo) -**Output**: Synthesized views from arbitrary camera positions - -### Method: - -1. Represent scene as a neural function: - -$$ -F(\mathbf{x}, \mathbf{d}) \rightarrow (c, \sigma) -$$ - - where: - - * $\mathbf{x}$ : 3D location - * $\mathbf{d}$ : viewing direction - * $c$ : color - * $\sigma$ : density - -2. Render images via **volume rendering** along camera rays. - - **Introduced in**: -*“NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis” (Mildenhall et al., ECCV 2020)* - -### Pros: - -* Extremely high-quality rendering -* Supports complex geometry and view-dependent lighting - -### Cons: - -* Expensive to train and render -* Needs many views with accurate camera poses - ---- - -## 4. **Flow-based View Synthesis** - -**Input**: Source image(s), predicted optical flow (or disparity) -**Output**: Warp source images to target view using learned flow fields - - Examples: - -* *DeepStereo (Flynn et al.)* -* *SynSin (Wiles et al.)* - -### Method: - -* Predict a dense pixel correspondence (flow or disparity) between views -* Warp source image using this mapping -* Fill holes with learned refinement network - ---- - -## 5. **Image-to-Image Translation with Pose Conditioning** - -**Input**: Source image + target pose or viewpoint -**Output**: Synthesized novel view - - Examples: - -* *Pix2Pix-style models with pose* -* *ViewNet, GQN (Generative Query Networks)* - -### Method: - -* Train a conditional GAN or autoencoder that learns to “imagine” the new view -* Implicitly encodes scene geometry - -### Limitation: - -* Poor geometric consistency -* Generalizes poorly outside training distribution - ---- - -## Summary Table - -| Method | Requires Depth? | Requires Multiple Views? | Pros | Cons | -| --------------------- | --------------- | ------------------------ | -------------------------- | -------------------------------- | -| Depth-based Warping | Yes | Single View OK | Simple, geometric | Artifacts, no occlusion handling | -| MPI | No (learned) | Few views preferred | Layered representation | Discrete planes, training needed | -| NeRF | No | Yes (many) | Photorealistic synthesis | Slow, memory-heavy | -| Flow-based Synthesis | No | Usually | Uses pixel correspondences | Warping artifacts | -| Pose-conditioned GANs | No | No (can be single view) | Fully learned | Low fidelity, hallucination | - ---- - -## **Validity of depth-based warping and correspondence matching** -**Lambertian reflectance** plays a **central role** in many view synthesis and depth estimation techniques - -## What is Lambertian Reflectance? - -A surface is **Lambertian** if its observed intensity **does not depend on the viewing direction** — it reflects light equally in all directions. The observed brightness $I$ at a point on such a surface is given by: - -$$ -I = \rho \cdot (\mathbf{n} \cdot \mathbf{l}) -$$ - -Where: - -* $\rho$: surface albedo (diffuse reflectance) -* $\mathbf{n}$: surface normal -* $\mathbf{l}$: light direction - -**Key idea**: For a Lambertian surface, **the observed color remains constant across viewpoints**, as long as lighting is fixed. - ---- - -## Why is this Important for View Synthesis? - -### Assumption in Disparity Estimation - -Stereo matching, optical flow, and depth-from-defocus often rely on **photometric consistency**: - -$$ -I_1(u, v) \approx I_2(u + d(u, v), v) -$$ - -This assumes that the **appearance of a 3D point remains the same** in both images — i.e., the scene is **Lambertian**. - -If surfaces reflect specularly or change appearance with viewing angle (e.g., glass, metal), this assumption breaks. - ---- - -### Depth-based Image Warping and Lambertianity - -When synthesizing a novel view using depth-based warping: - -1. You reproject 3D points into the novel view. -2. You copy the original **color** of the point from the input image. - -This is **only valid** if the appearance of the point is **view-independent** — i.e., Lambertian. - -Otherwise: - -* The true appearance in the target view might differ -* The rendered view will have **artifacts**, especially at specular regions - ---- - -## Non-Lambertian Effects Break Photometric Consistency - -Here are the effects that violate the assumption: - -| Violation | Effect on View Synthesis | -| --------------------------- | ---------------------------------------------- | -| **Specular Reflection** | Appearance changes drastically with viewpoint | -| **Transparency/Refractive** | Scene geometry is non-single-valued along rays | -| **Subsurface Scattering** | Light interacts complexly within surface | -| **Occlusion Boundaries** | New surfaces are revealed or hidden | - -These can result in: - -* Incorrect disparity estimation -* Warping artifacts (ghosting, stretching) -* Poor matching in optical flow - ---- - -## How Do Methods Handle Non-Lambertian Surfaces? - -### In Classical Stereo/Depth: - -* Specular highlights and reflective surfaces are **ignored or masked** -* Robust matching costs (e.g., Census, NCC) are used instead of pure pixel-wise differences - -### In Learning-Based Models: - -* Networks can **learn to ignore** specular regions if trained on real data -* **Photometric loss is often combined with SSIM**, which is more tolerant to illumination and contrast changes: - - $$ - \mathcal{L}_{\text{photo}} = \alpha \cdot \text{SSIM}(I, \hat{I}) + (1 - \alpha) \cdot \|I - \hat{I}\|_1 - $$ - -### In Advanced Rendering (e.g., NeRF): - -NeRF explicitly models **view-dependent effects** by conditioning the neural radiance field on the **viewing direction** $\mathbf{d}$: - -$$ -F(\mathbf{x}, \mathbf{d}) \rightarrow (c, \sigma) -$$ - -This allows it to learn both Lambertian and non-Lambertian behavior: - -* For diffuse surfaces: $c \approx \text{constant w.r.t } \mathbf{d}$ -* For specular surfaces: $c$ varies with direction - ---- - -## Takeaway: Lambertian Reflectance is a Foundational Assumption - -| Task | Depends on Lambertian Assumption? | Notes | -| ------------------- | --------------------------------- | -------------------------------------------- | -| Stereo Matching | Strongly depends | Assumes appearance doesn’t change | -| Depth-based Warping | For color warping | View-independent color assumed | -| MPI | Partially | May model occlusions but not view-dependence | -| NeRF | Not required | Learns non-Lambertian effects | -| GAN-based Synthesis | Not required | May hallucinate instead of modeling geometry | - ---- - - -## Key Challenges in **Monocular real-time depth and shape estimation** - -### Ambiguities: - -* **Scale ambiguity**: Monocular depth can only be predicted up to scale unless external cues (e.g. ground plane, known object sizes) are used. -* **Occlusions and disocclusions**: No information from other views to resolve visibility. -* **Specular and non-Lambertian surfaces**: Break appearance-based cues. - -### Real-Time Constraints: - -* Model must be **lightweight** and run at **30+ FPS**, especially on edge devices. -* **Low-latency** inference with high **spatial resolution**. - ---- - -## Core Methods - -### 1. **Monocular Depth Estimation (Supervised or Self-supervised)** - -#### Supervised (with GT Depth) - -* DPT, MiDaS (ViT-based) — good but not real-time -* Lightweight CNNs (e.g., MobileDepth, FastDepth) - -#### Self-Supervised (using photometric loss and pose) - -* *Monodepth2* (Godard et al.) -* *ManyDepth*, *PackNet*, *RAFT-Stereo adapted* - -> These methods use image reconstruction losses with view synthesis, and are often trained on stereo or monocular video. - ---- - -### 2. **Real-Time Models for Monocular Depth** - -| Model | FPS (GPU) | Params | Notes | -| ---------------------------------------- | --------- | ------ | ------------------------------------ | -| FastDepth | \~100 | 4.7M | MobileNet + efficient decoder | -| Lite-Mono | \~60 | \~2M | Fast self-supervised monocular depth | -| DensePrediction Transformer Tiny (DPT-T) | \~20 | \~25M | Higher quality, slower | - -For real-time: - -* Consider encoder-decoder architectures with **depthwise separable convolutions** or **NAS-designed** models. -* Replace bilinear upsampling with learned, efficient upsampling (e.g. pixel shuffle, sub-pixel convolutions). - ---- - -## Advanced Shape Representation (Beyond Per-pixel Depth) - -### 1. **Surface Normals + Depth Joint Prediction** - -* Predicting **normals**, **depth**, and **edges** improves geometric consistency. -* You can enforce constraints like: - - $$ - \mathbf{n}(x) = \frac{(-\partial Z / \partial x, -\partial Z / \partial y, 1)}{\| \cdot \|} - $$ - -### 2. **Depth + 3D Shape via Implicit Representations** - -* Recent monocular models predict **signed distance fields (SDFs)** or **occupancy maps**: - - * *Monocular Neural Implicit Reconstruction* - * *MonoSDF* (ICCV 2023): infers SDFs from single-view - -> Though more expressive, these are typically too heavy for real-time without simplification. - ---- - -### 3. **Keypoint/Structure from Motion Integration** - -Combine learning with classic structure-from-motion (SfM) cues: - -* **SIFT/ORB + learned matching** (e.g., SuperPoint + SuperGlue) -* Lightweight SLAM backends fused with monocular depth - ---- - -## Possible Enhancements for Real-Time Use - -* **Temporal consistency**: Enforce smoothness across frames (e.g., 3D warping with ego-motion). -* **Knowledge distillation**: From larger teacher models (e.g., MiDaS → FastDepth). -* **Multi-task learning**: Predict depth, normals, and semantics together for mutual reinforcement. -* **On-device optimization**: Prune, quantize, or compile (e.g., TensorRT, ONNX) for deployment. -

-Use browser-based APIs (e.g., getUserMedia) for WebAssembly compatibility. - -Object Detection: -Use a lightweight model like MobileNet-SSD or YOLO-Tiny (pre-trained for common objects: sidewalk, wall, car, swing). - -Processing time: ~15–30 ms on mid-range devices for 720p. - -Output: Bounding boxes and labels for objects (e.g., “sidewalk: center, wall: left”). - -Feature Extraction: -Analyze color and texture within bounding boxes using OpenCV’s image processing (e.g., HSV color histograms, edge detection). - -Example: Sidewalk = smooth, gray (low-frequency hum); wall = flat, textured (mid-frequency tone). - -Processing time: ~5–10 ms. - -Depth Estimation: -Use a lightweight monocular depth model (e.g., MiDaS Small, optimized for TFLite) to estimate object distances. - -Example: Swing at 2m = loud, broad sound; at 5m = quiet, narrow sound. - -Processing time: ~20–30 ms on flagships, ~30–50 ms on mid-range. - -Alternative: Use motion cues (e.g., optical flow) for faster processing (~10–20 ms). - -Audio Mapping: -Map visual features to audio cues using Web Audio API: -Position: Stereo panning (left-right based on bounding box x-coordinate). - -Depth: Volume (louder for closer) and spectral complexity (broader for closer). -

-Lightweight models: Use quantized TFLite models (e.g., MobileNet-SSD, MiDaS Small) for 2–3x speedup. - -Frame skipping: Process every other frame (effective 15 FPS) if needed, while interpolating audio cues. - -GPU/Neural acceleration: Leverage OpenCV’s DNN module with OpenCL or mobile neural engines. - -Asynchronous processing: Run image processing in parallel with audio synthesis to reduce perceived latency. - -Audio Cue Design -Number of cues: Limit to 3–6 per 66ms frame (e.g., sidewalk, wall, swing) to ensure auditory clarity, based on the 5–10 ms per cue limit from our previous discussion. - -Spectral signatures: -Sidewalk: Low-pass noise (100–200 Hz), center-panned, steady. - -Wall: Sine wave (500–1000 Hz), left-panned, constant. - -Swing: Sawtooth wave (200–2000 Hz), center-panned, dynamic volume/filter. - -Car: Bandpass noise (500–5000 Hz), panned based on position. - -Dynamic updates: Adjust volume and filter cutoff every 66ms based on depth/motion (e.g., swing closer = louder, broader spectrum). -

Core Operating Paradigms: Flow and Focus + +To serve the distinct needs of active navigation and detailed exploration, AcoustSee is built on two core operating paradigms. The application can be switched between these modes by the user. This dual-mode architecture is a fundamental design principle. (See ADR-0002 for details). + +* **Navigation Mode ("Flow Mode"):** + * **Goal:** Provide real-time, low-latency spatial awareness for safe movement. + * **Behavior:** Uses fast, abstract processing to create a textural soundscape representing the shape of the environment. Performance is prioritized over detail. + +* **Identification Mode ("Focus Mode"):** + * **Goal:** Provide detailed, semantic information about specific objects in the user's vicinity. + * **Behavior:** Engages computationally intensive Machine Learning models (e.g., object segmentation, depth estimation) to trigger specific, recognizable "AcousticCues." Accuracy is prioritized over speed. + + +## 2.5. Architectural Pattern: Hexagonal Architecture (Ports & Adapters) + +To ensure true modularity and testability, AcoustSee is designed following the principles of **Hexagonal Architecture**, also known as the **Ports and Adapters** pattern. The core principle is to isolate the application's central logic from external technologies and frameworks. + +This creates a clean separation of concerns, allowing different "pipelines" (UI, Audio, Video) to be developed and tested independently. + +### The Hexagon: The Application Core + +The "Hexagon" represents the pure, business logic of the application. It has no knowledge of the outside world (like the DOM, Web Audio API, or specific ML models). + +* **Implementation:** `web/core/engine.js` +* **Responsibility:** Manages application state and orchestrates commands. It is the single source of truth for the application's behavior. + +### The Ports: The Formal API + +The Hexagon defines "Ports," which are the formal, technology-agnostic APIs for interacting with the core. + +1. **Inbound Port (Driving Port):** This is the API for telling the application to *do something*. + * **Implementation:** The `engine.dispatch('command', payload)` method. + * **Contract:** All external interactions that modify or query the application state *must* go through the `dispatch` method. + +2. **Outbound Port (Driven Port):** This is the API for the application to announce that *something has happened*. + * **Implementation:** The `engine.on('event', listener)` method and the `engine.onStateChange(listener)` subscription. + * **Contract:** The core notifies the outside world of changes via these event listeners. It does not call external modules directly. + +### The Adapters: The Outside World + +"Adapters" are the pluggable modules that connect external technologies to the Hexagon's Ports. They are responsible for translating between the specific technology and the application's generic commands and events. + +* **UI Adapters (`web/ui/`):** + * **Technology:** The Browser DOM (clicks, swipes, etc.). + * **Function:** They listen for raw user input and *adapt* it into formal commands (e.g., a `click` becomes `dispatch('toggleProcessing')`). They also listen for state changes from the engine to update the screen. + +* **Audio Adapter (`web/audio/`):** + * **Technology:** The Web Audio API. + * **Function:** It listens for a generic `playCues` command from the engine and *adapts* it into specific Web Audio API calls (`createOscillator`, `.start()`, etc.). The engine itself does not know what an oscillator is. + +* **Video Adapter (`web/video/`):** + * **Technology:** Camera streams, Web Workers, and ML models. + * **Function:** It adapts raw video frames into meaningful data (like motion regions or identified objects) and can be triggered by commands from the engine. + +* **Test Adapters (`/test/`):** + * **Technology:** A testing framework (e.g., Playwright, Jest). + * **Function:** A test script acts as another adapter. It drives the application through the `dispatch` port and verifies outcomes by listening to the `onStateChange` port, all without needing a real browser or UI. + +This architecture is the key to maintaining the project's integrity while allowing for independent, "pipeline-based" development. + +### Visual Diagram + +Below is a small diagram illustrating the Hexagonal Architecture mapping used by AcoustSee. The Application Core (the hexagon center) exposes ports; Adapters connect the outside world to those ports. + +![Hexagonal Architecture diagram](./docs/hexagonal-architecture.svg) + + + +## 3. Development Process + +To prevent rework and ensure clarity, this project follows a lightweight development process based on documented tasks and architectural decisions. + +* **Task Tracking (`TASKS.md`):** All significant work is tracked in the `TASKS.md` file at the project root. Before starting work, please consult this file. All commits and Pull Requests should reference a Task ID (e.g., `PERF-1`). +* **Architectural Decisions (`docs/adr/`):** Major architectural decisions are documented as Architectural Decision Records (ADRs) in the `docs/adr/` directory. These serve as the rationale for the project's structure. +* **Work-in-Progress (WIP):** Code that is experimental or incomplete **must** be wrapped in a `WIP` comment block that references its Task ID. This protects it from premature refactoring. + *Example:* + ```javascript + // --- WIP: PERF-1 --- + // This logic is experimental. Do not modify without consulting TASKS.md. + // --- END WIP --- + ``` + +## 4. Headless Engine Pattern +- `web/core/` contains the headless Engine and command handlers. +- Core modules must not access `window`, `document`, or import anything from `web/ui/`. +- The Engine exposes `engine.dispatch(command, payload)` and registers command handlers in `web/core/commands/`. +- Command handlers return structured results (objects) and should not throw uncaught errors. + +### Command Handler Categories +- `media-commands.js` — Camera, microphone, and media stream management +- `settings-commands.js` — Configuration and user preferences +- `diagnostics-commands.js` — Performance measurement, AutoFPS, and system diagnostics +- `debug-commands.js` — Development and debugging utilities + +## 5. Directory Responsibilities +- `web/core/` — state machine, command registration, headless business logic. +- `web/core/commands/` — grouped command implementations (media, settings, diagnostics, debug). +- `web/core/scheduler.js` — lightweight diagnostic scheduler for performance management. +- `web/ui/` — pluggable UI modules; each UI lives in its own subdirectory (e.g., `ui/dev-panel/`, `ui/touch-gestures/`). +- `web/audio/`, `web/video/`, `web/utils/` — well-scoped helpers and workers. UI-specific helpers (for example worker monitors) may be colocated under `web/ui//`. + +## 6. Pluggable UI Contract +Each UI module must: +- Live under `web/ui//`. +- Export `initializeUI(engine, DOM, options = {})` (exact export name documented in the module README). Note: for the development dashboard the canonical module is `ui/dev-panel/` and it registers its initializer with the `ui-registry` (see below). +- Create its DOM under a provided root (use `DOM.uiPanelRoot` if supplied). +- Load its own stylesheet dynamically and run DOM measurement/wiring only in `link.onload`. +- Use scoped IDs/prefixes to avoid collisions (e.g., `acoustsee-devpanel-*`). +- Use event delegation where possible and avoid fragile index-based child access. +- Return a `dispose()` function (or attach it to the panel) that removes event listeners, clears intervals, stops polling, and removes created DOM. + +Example signature: +```js +export function initializeDebugUI(engine, DOM, options = {}) { + // returns { dispose() { ... } } +} +``` + +## 7. UI Submodule Structure +A UI directory should contain: +- `.js` (coordinator, e.g. `dev-panel.js`) +- `.behavior.js` (layout/visual behavior) +- `.actions.js` (event wiring) +- `.controls.js` (factory helpers) +- `.css` (styles) +- `worker-charts.js` or other contained subcomponents + + +### ui-registry (recommended) +To avoid accidental global exports and to make dynamically-loaded UI modules discoverable to other boot-time handlers, the project provides a small `ui-registry` helper at `web/ui/ui-registry.js`. + +The registry exposes: +- `registerComponent(name, initializerFn)` — modules call this at load-time to make their initializer available. +- `getComponent(name)` — returns the initializer function previously registered (or `undefined`). + +Example usage from a UI module: +```js +import { registerComponent } from '../ui/ui-registry.js'; +// Note: Dev panel initializer now follows a simplified signature. When running in +// debug mode the panel is initialized and shown immediately by calling: +export function initializeDevPanel(engine, DOM) { /* ... */ } +registerComponent('dev-panel', initializeDevPanel); +// Deprecated: previous versions accepted an `options` object (for example +// `autoOpen`) — that behavior has been removed. Use `?debug=true` in the URL +// to ensure the dev panel is loaded and visible at boot. +``` + +## 8. Video Subsystem: The Adaptive Frame Processing Pipeline + +The video subsystem captures and analyzes camera input using an intelligent, performance-aware architecture. + +### Core Architecture: FrameProvider + Orchestrator + Specialists + +* **FrameProvider Worker:** A dedicated worker that isolates camera access. It runs its own `requestAnimationFrame` loop to provide a clean, steady stream of video frames, tagging each with timing metadata for performance measurement. +* **Orchestrator (`frame-processor.js`):** The central brain of the video pipeline. It receives frames from the `FrameProvider` and, based on the application's current mode (`flow` vs. `focus`), delegates analysis tasks to the appropriate specialist workers. +* **Specialist Workers (`motion-worker.js`, `depth-worker.js`, etc.):** Each specialist is an expert in a single, computationally expensive task (e.g., motion detection, depth estimation, object recognition). They return structured, semantic data. + * **`motion-worker.js`:** Real-time optical flow and motion magnitude computation; fast, CPU-based. + * **`depth-worker.js`:** Monocular depth estimation with dual paths: GPU-accelerated CNN (WebGPU compute shaders) with CPU fallback, or fast CPU-only Sobel edge detection. See ADR-0005 for WebGPU acceleration strategy. +* **Grids (`grids/`):** Pluggable **"Sonic Sculptor"** modules. Their role changes based on the mode: + * **In `Flow` Mode:** They translate unstructured spatial data (like raw motion) into a musical concept, creating an ambient soundscape. Example: `linear-pitch.js`. + * **In `Focus` Mode:** They translate structured semantic data from the specialists (like a detected object's shape or form) into a specific sonic signature, like a melody or arpeggio, effectively "drawing" the object's form with sound. // R161025 "structured semantic data" we might want to revisit this apprach, i dont think we need this complexity of semantic data, instead we should try to handle "abstract" data and to transforn it into sound, as direct as we can, lightweight in all termns. + +### Data Flow & Output Contract + +The Orchestrator coordinates the specialists and the active Grid to produce the final output: an array of `cues`. This array is then dispatched in an `'audioCuesReady'` event. The content and richness of these cues adapt to both the operating mode and real-time performance constraints. + +### 8.1 Depth Worker: GPU-Accelerated Monocular Depth Estimation + +The `depth-worker.js` specialist provides real-time, relative depth information for melody modulation and spatial scene understanding. It implements a hybrid architecture combining GPU acceleration with CPU fallback for compatibility. + +#### Design Overview + +The depth worker supports two distinct computational paths, selected via the `path` parameter: + +1. **CNN Path (GPU-Accelerated):** Uses a minimal U-Net encoder-decoder architecture with WebGPU compute shaders for 2D convolution operations. + - **Encoder:** 3 GPU-accelerated convolutional layers with ReLU activation. + - **Decoder:** Bilinear upsampling + convolutional layers to reconstruct full-resolution depth map. + - **Fallback:** If WebGPU unavailable or fails, automatically switches to CPU-only vanilla JS implementation. + - **Output:** Flattened depth map [0, 1] averaged into grid cells per paradigm. + +2. **Pseudo-Depth Path (CPU-Only):** Fast, dependency-free approach using Sobel edge detection. + - **Sobel operator:** Detects edges via gradient magnitude; high-gradient regions → close objects. + - **Softplus normalization:** `log(1 + exp(x))` maps edge magnitude to [0, ∞) → [0, 1]. + - **Gabor texture enhancement:** Optional; refines collision detection via Gabor-kernel correlation. + - **Sampling:** Every 30 pixels per grid cell for speed; skip cells with depth < 0.2. + +#### GPU Acceleration Strategy (WebGPU) + +**See ADR-0005 for complete rationale and implementation details.** + +- **Compute Shader (WGSL):** Parallelizes 2D convolution across GPU threads; workgroup size 256 for efficient utilization. +- **Buffer Management:** Async GPU buffer creation, data transfer, bind group setup, and readback. +- **Device Caching:** GPU device initialized once and cached to avoid repeated adapter/device creation overhead. +- **Graceful Fallback:** Any GPU failure (initialization, shader compilation, device loss) automatically triggers CPU path without interrupting playback. +- **Structured Logging:** Sampled logs (1% sample rate) for GPU operation monitoring without console spam. + +#### Message Contract + +**Input:** `{ type: 'processFrame', frame: ImageData, gridSize: { rows: 4, cols: 4 }, path: 'cnn'|'pseudo' }` + +**Output:** `{ type: 'depthCues', result: { gridDepths: [[...], ...], timestamp: number } }` + +- `gridDepths`: 2D array [rows][cols] with averaged depth per grid cell, normalized to [0, 1]. +- `timestamp`: Frame processing completion time for diagnostics. + +#### Performance Characteristics + +- **Pseudo-depth path:** 20-40ms for 640×480 (CPU-only, no GPU overhead). +- **CNN path (GPU available):** 50-150ms for 640×480 encoder-decoder (10x faster than pure CPU). +- **CNN path (GPU unavailable):** 500-1000ms for 640×480 (falls back to vanilla JS conv2d). + +#### Error Handling & Resilience + +- **GPU initialization failure:** Log warning, use CPU path for all subsequent frames. +- **GPU shader compilation failure:** Catch exception, fall back to CPU for that frame; retry GPU on next frame. +- **Device loss:** Clear cached device; re-initialize on next frame with exponential backoff. +- **Out-of-memory:** GPU buffer allocation failure triggers automatic CPU path. + +#### Integration Notes + +- Used in **Focus Mode** (ML-1) for melody modulation via depth grid. +- Can be triggered at lower latency (<45ms) via frame skipping (every 2nd frame) for real-time responsiveness. +- Compatible with both paradigms; CNN path provides richer depth detail, pseudo-depth path prioritizes speed. + +### 8.2 Paradigm-Aware Grid Configuration (ARCH-3.5) + +The `grid-config.js` module provides centralized, paradigm-aware grid sizing and aggregation strategy management. This design enables adaptive performance tuning and data-driven workflow decisions across all video workers. + +#### Grid Configurations by Paradigm + +Each paradigm defines an optimal grid size and aggregation strategy: + +| Paradigm | Grid Size | Aggregation | Skip Threshold | Purpose | +| :--- | :--- | :--- | :--- | :--- | +| **Flow** | 3×3 (9 cells) | `mean` | 0.1 | Fast, lightweight; responsive navigation feedback | +| **Focus** | 8×8 (64 cells) | `max` | 0.05 | High-resolution detail; precision object identification | +| **Hybrid** | 5×5 (25 cells) | `weighted` | 0.075 | Balanced; moderate resolution with real-time responsiveness | + +#### Stateless Worker Pattern (R171025 Refactoring) // R171025v2 i dont we whould document this, at least not in architecture, this is more of a changelog. + +Workers no longer maintain configuration state. This eliminates race conditions and makes the system more debuggable: + +**Before (Problematic):** +```javascript +// ❌ Workers stored mutable state +let _currentGridConfig = { rows: 4, cols: 4, ... }; +self.onmessage = (e) => { + if (e.data.type === 'configure') { + _currentGridConfig = e.data.gridConfig; // Silent state mutation + } + if (e.data.type === 'processFrame') { + // Uses stale _currentGridConfig if configure message was dropped + } +}; +``` + +**After (Fixed - Stateless):** +```javascript +// ✅ Configuration flows in with every frame +self.onmessage = (e) => { + const { type, frame, gridConfig, mode, enableSemantic } = e.data; + if (type === 'processFrame') { + // Use gridConfig directly - no stored state + const { rows, cols, aggregation, skipThreshold } = gridConfig; + // Process using local parameters only + } +}; +``` + +**Benefits:** +- **No race conditions:** Workers never have stale config +- **Atomic frames:** Each frame is self-contained with full config +- **Debuggable:** DevTools shows gridConfig for every frame +- **Testable:** No mutable worker state to manage + +#### Message Flow + +The `frame-processor.js` orchestrator sends grid configuration with every frame: // R171025 i would like to know the overhead of having the grid configuration passed on every frame, lets consider that we aim to have between 5 and 15 frames per second + +1. **Initialization:** When engine loads, `frame-processor.js` imports `getGridConfig` from `grid-config.js`. +2. **State Management:** Engine maintains `state.currentMode` and `state.enableSemanticDetection`. +3. **Frame Processing:** For each frame, `frame-processor.js`: + - Derives `gridConfig = getGridConfig(state.currentMode)` + - Sends: `{ type: 'processFrame', frame, gridConfig, mode, enableSemantic }` + - Workers receive fresh config with every frame (stateless) +4. **No Handshake:** Workers don't need `configure`/`ready` messages; config arrives inline with data + +#### Signal Path: Abstract Features (Primary) + Optional Semantic Layer + +All workers extract **abstract spatial features** as the primary signal path: + +- **Motion Worker** (`motion-worker.js`): Lucas-Kanade optical flow → grid flow magnitudes → `motionCues` +- **Image Worker** (`image-worker.js`): + - Primary: Extract abstract features (`textureRich`, `fastMotion`, `edgeConcentration`) + - Optional: Heuristic semantic detection (person, tree, rough_ground, trash, box) — disabled by default, togglable via `state.enableSemanticDetection` + - Emit `flowCues` with both abstract features and conditionally-included semantic objects +- **Depth Worker** (`depth-worker.js`): Sobel/CNN depth → grid depths → `depthCues` with grid metadata + +#### Semantic Detection Control + +Semantic detection is configurable and disabled by default for performance: + +**In Engine State (`core/state.js`):** +```javascript +{ + enableSemanticDetection: false, // Opt-in for educational exploration + currentMode: 'flow', // Can be 'flow', 'focus', or 'hybrid' +} +``` + +**Toggle via Command (settings-commands.js):** +```javascript +engine.dispatch('toggleSemanticDetection', { enabled: true }); +// or toggle current state: +engine.dispatch('toggleSemanticDetection', {}); +``` + +**Flow to Workers:** +```javascript +// frame-processor.js derives current state each frame +imageWorker.postMessage({ + type: 'processFrame', + frame, + gridConfig, + mode, + enableSemantic: state.enableSemanticDetection // From engine state +}); +``` + +#### Feature Detector Module (`feature-detector.js`) + +The `SemanticFeatureDetector` class provides optional, lightweight heuristic-based object detection for educational/community exploration: + +- **5 Detection Methods:** person (vertical motion + edges), tree (textured vertical + stable), rough_ground (noisy high-frequency), trash (clustered low-confidence regions), box (rectangular boundaries) +- **Threshold-Based:** No ML models; uses Gabor filters, histogram analysis, and gradient patterns — designed for student learning +- **Opt-In:** Only runs when `enableSemanticDetection=true`; does not affect core audio generation +- **Confidence Scoring:** Each detection includes reasoning and confidence metric for uncertainty handling +- **Educational Value:** Community can explore and improve heuristics without ML complexity + +**See Also:** [Semantic Detection: Educational Guide to Computer Vision in AcoustSee](../../docs/SEMANTIC_DETECTION_GUIDE.md) — A comprehensive walkthrough of all detection methods, thresholds, algorithms, and how to extend the system for student projects. + +#### Benefits + +- **Performance Tuning:** Flow mode uses fast 3×3 grids for responsiveness; Focus mode scales to 8×8 for precision +- **Clean Separation:** Abstract features drive real-time audio; semantic detection available for educational/community extensions +- **Flexible Configuration:** Grid config and semantic detection toggle dynamically without worker restarts +- **Backward Compatibility:** Workers accept both legacy `gridSize` parameter and new `gridConfig` parameter +- **Debuggable:** Every frame message contains full configuration; no hidden worker state + +## 9. Audio Subsystem: The Adaptive Conductor + +The audio subsystem, orchestrated by the `playCues` "Conductor," translates `cues` into sound. Its output also adapts to the current operating mode. + +* **The Conductor Pattern:** The core pattern remains the same: `playCues` maps `cues` to synthesizers via the `sound-profiles.js` manifest. +* **In Flow Mode:** It generates continuous, textural, and abstract soundscapes designed for spatial awareness. Synthesizers used in this mode are optimized for responsiveness and clarity. +* **In Focus Mode:** It generates discrete, specific, and recognizable sounds ("AcousticCues") that correspond to identified objects. The sound profiles for this mode are semantically rich (e.g., a glass synth for a `glass` objectType). + +## 10. Performance Management: The AutoFPS Feedback Loop + +AcoustSee implements an intelligent, closed-loop performance management system that automatically adjusts processing workload to maintain responsiveness and battery efficiency. + +### The New, Modern System (How We Do It Now) + +Our new system is a true, closed-loop feedback system made of several cooperating components. It separates the job of *processing* from the job of *measuring and adjusting*. + +| Component | Responsibility | How it Works (The New AutoFPS) | +| :--- | :--- | :--- | +| **1. `FrameProvider` Worker** | **Process as fast as possible.** | It runs a `requestAnimationFrame` loop, providing a constant stream of frames at the maximum possible speed. Crucially, it **tags each frame** with a `startTime`. | +| **2. `Sonification Handler`** | **Measure the real work.** | At the very end of the entire pipeline, it receives the final cues. It calculates `endTime - startTime` to get the **actual, measured duration** it took to process that specific frame. It then dispatches this measurement via `'logFrameBenchmark'`. | +| **3. `Diagnostics Handler`** | **Collect the data.** | It listens for `'logFrameBenchmark'` events and collects the real-world performance data into a rolling buffer (the `RingBuffer`). It knows exactly how "expensive" our pipeline is. | +| **4. The New `Scheduler`** | **Be the "manager" who checks in.** | This is a slow, low-priority loop. It runs infrequently (e.g., once or twice a second) and dispatches a `'diagnosticTick'`. Its only job is to ask the question, "Is it time to review our performance?" | +| **5. The `Diagnostics Handler` (Again)** | **Make an intelligent decision.** | When it receives the `'diagnosticTick'`, it analyzes the collected performance data. It asks: "Based on the last 30 frames, are we running efficiently, or are we struggling?" | +| **6. The `FrameProvider` (Again)** | **The "Throttle"** | This is the final piece. The `Diagnostics Handler` doesn't directly control the FPS. Instead, it can dispatch a command to tell the `FrameProvider` to change its behavior. For example, it could tell it to **start skipping frames** (e.g., "only process every other frame") or to **reduce the resolution** of the `ImageData` it sends back. This is how it adjusts the workload to meet the performance target. The `updateInterval` in the state becomes the *goal* that this system tries to achieve. | + +**In summary:** The new system is an intelligent feedback loop. It **measures the real-world cost** of our pipeline and then **adjusts the workload** to ensure the application stays responsive and battery-efficient. + +### Command Flow for Performance Management + +- **Performance Measurement:** `logFrameBenchmark` → Diagnostics Handler +- **Performance Review:** `diagnosticTick` → Diagnostics Handler analysis +- **Workload Adjustment:** Diagnostics Handler → `setFrameInterval`, `setFpsMode` commands to FrameProvider + +### Implementation Files + +- `core/scheduler.js` — The lightweight diagnostic scheduler +- `core/commands/diagnostics-commands.js` — Performance measurement and adjustment handlers +- `video/frame-provider-worker.js` — The adaptive frame processing worker +- `audio/hrtf-processor.js` — End-of-pipeline measurement point + +## 11. Guardrails — What Not To Do +- Do not add business logic to `core/engine.js`. +- Do not import UI modules into `core/` — enforce via lint rule. +- Do not create manual frame processing loops — use the FrameProvider worker system. +- Do not implement custom FPS throttling — use the AutoFPS feedback loop via diagnostics commands. +- Avoid fragile DOM access by index; prefer data-action attributes and delegation. +- Avoid creating global IDs without module prefix. +- Avoid starting polling/intervals without exposing a dispose that stops them. + +### Common LLM Refactoring Anti-Patterns (DO NOT DO THESE) + +These are common mistakes that AI coding assistants make when refactoring code. **Do not make these changes:** + +#### ❌ Anti-Pattern 1: "Simplifying" Context Destructuring +```javascript +// WRONG: LLMs often "simplify" by removing unused variables +const { audioContext, getOscillator } = ctx; +// But synths MUST extract ALL dependencies they use: +const { audioContext, getOscillator, masterGain, oscillatorPool } = ctx; +``` + +**Rule:** Synths must explicitly destructure ALL dependencies from `ctx`. JavaScript won't error until runtime access. + +#### ❌ Anti-Pattern 2: "Cleaning Up" Oscillator Connections +```javascript +// WRONG: LLMs see "unused" masterGain and remove the connection +panner.connect(audioContext.destination); + +// CORRECT: ALL synths MUST connect to masterGain for volume control +panner.connect(masterGain); +``` + +**Rule:** Audio graph MUST terminate at `masterGain`, never at `audioContext.destination` directly. + +#### ❌ Anti-Pattern 3: "Optimizing" Karplus-Strong Feedback +```javascript +// WRONG: LLMs see 0.90 and "optimize" to 0.98 for "better sustain" +const decay = 0.98; // Causes exponential resonance! + +// CORRECT: Feedback gain MUST be < 0.95 for stability +const decay = 0.90; // Safe range: 0.85-0.95 +``` + +**Rule:** Karplus-Strong feedback gain > 0.95 causes runaway resonance. Keep it in the 0.85-0.95 range. + +#### ❌ Anti-Pattern 4: "Consolidating" UI Imports +```javascript +// WRONG: LLMs try to "organize" imports by pulling in core modules +import { engine } from '../../core/engine.js'; + +// CORRECT: UI modules MUST receive engine via dependency injection +export function initializeMyUI(engine, DOM) { ... } +``` + +**Rule:** UI modules MUST NOT import from `core/`. They receive dependencies as parameters. + +#### ❌ Anti-Pattern 5: "Simplifying" Worker Message Handling +```javascript +// WRONG: LLMs "simplify" by removing message type checks +worker.onmessage = (e) => { + const data = e.data; + handleFrame(data); +}; + +// CORRECT: ALWAYS check message type for robustness +worker.onmessage = (e) => { + const { type, result } = e.data; + if (type === 'result') handleFrame(result); + else if (type === 'error') handleError(result); +}; +``` + +**Rule:** Worker message handlers MUST check `type` field. Workers send multiple message types. + +#### ❌ Anti-Pattern 6: "Removing Redundant" Dispose Functions +```javascript +// WRONG: LLMs see empty dispose and remove it +// (Then later code breaks when it tries to call dispose) + +// CORRECT: ALL UI modules MUST return dispose, even if empty +export function initializeMyUI(engine, DOM) { + // ... setup code ... + return { dispose: () => {} }; // Will be filled in later +} +``` + +**Rule:** ALL UI modules MUST return a `dispose()` function. Empty is fine, but it must exist. + +#### ❌ Anti-Pattern 7: "Fixing" Performance by Removing Sampling +```javascript +// WRONG: LLMs see conditional logging and "simplify" it +structuredLog('DEBUG', 'Frame processed', { frameId }); + +// CORRECT: High-frequency logs MUST use sampling +if (Math.random() < 0.01) { + structuredLog('DEBUG', 'Frame processed', { frameId }); +} +``` + +**Rule:** Per-frame logs MUST be sampled (1% or less) to prevent performance degradation. + +## 12. CSS & Layout Rules +- UI modules must load CSS via a `` element and do layout in `link.onload`. +- Use a consistent stylesheet path resolution strategy (absolute or `document.baseURI`-aware`). +- Controls should use responsive two-column grids where appropriate. + +## 13. Error Reporting and Logging +- Core: structured logging (level, message, meta). Command handlers should use structured log helpers. +- UI: non-blocking user notifications for errors; log to debug console pane. +- Each UI module should log its module load with version badge: `console.log('module loaded', BUILD_VERSION)` when available. + +### Performance Measurement +- Use `logFrameBenchmark` command to report frame processing times with `startTime` and `endTime`. +- Performance-critical code should participate in the AutoFPS feedback loop by dispatching timing measurements. +- Use the diagnostic scheduler (`diagnosticTick`) for infrequent performance analysis, not per-frame operations. +- Workers should tag frames with timing metadata to enable end-to-end measurement. + +## 14.

Key learnings: + +**Pool Contract:** +- The pool stores `{osc, gain, panner, active}` objects that are **unconnected and unstarted** +- Synths receive the pool via `ctx.oscillatorPool` and wire connections themselves +- Synths MUST extract `oscillatorPool` from `ctx` explicitly (no implicit access) +- Each oscillator can only call `.start()` once - must use fresh oscillators for new notes + +**Common Bug:** +```javascript +// WRONG: Forgot to extract oscillatorPool from ctx +export function playCues(cues, ctx) { + const { audioContext, getOscillator } = ctx; + oscillatorPool.forEach(...); // ReferenceError at runtime! +} + +// CORRECT: Extract all dependencies explicitly +export function playCues(cues, ctx) { + const { audioContext, getOscillator, masterGain, oscillatorPool } = ctx; + if (oscillatorPool && Array.isArray(oscillatorPool)) { + oscillatorPool.forEach(...); + } +} +``` + +### Karplus-Strong Synthesis Stability +Physical modeling synths (like plucked strings) require careful gain staging: + +**Feedback Gain Rules:** +- Feedback gain MUST be in range 0.85-0.95 for stability +- Values > 0.95 cause exponential signal growth (runaway resonance) +- Values < 0.85 cause premature decay (unrealistic sound) +- Default safe value: **0.90** + +**Amplitude Rules:** +- Noise excitation should be 0.2-0.4 (not 0.8+) +- Output amplitude should be scaled by intensity × 0.15 (not 0.3+) +- Always cap output amplitude to prevent clipping + +### Worker Message Contracts +All workers MUST send structured messages with a `type` field: + +```javascript +// Worker sends: +postMessage({ type: 'result', result: { data } }); +postMessage({ type: 'error', error: 'description' }); +postMessage({ type: 'ready', features: [] }); + +// Main thread handles: +worker.onmessage = (e) => { + const { type, result, error } = e.data; + if (type === 'result') handleResult(result); + else if (type === 'error') handleError(error); + else if (type === 'ready') handleReady(); +}; +``` + +### UI Disposal Requirements +ALL UI modules must provide disposal cleanup: + +**Required in dispose():** +- Remove ALL event listeners (DOM, engine, workers) +- Clear ALL intervals and timeouts +- Stop ALL polling loops +- Remove ALL created DOM elements +- Terminate ALL workers +- Close ALL persistent connections + +**Empty dispose is acceptable** during initial development, but must be filled in before PR. + +## 16. Accessibility & Internationalization +- All interactive elements must provide keyboard access and ARIA attributes. +- Text must be extracted into `web/languages/` and UIs must support locale injection. + +## 17. Versioning & Releases +- Expose BUILD_VERSION in `web/core/constants.js`. UIs should display the version badge. +- Keep changelog entries for architectural changes. + +## 18. Onboarding & Maintenance +- Each UI folder must contain a README describing its public API and lifecycle (initialize + dispose). +- Keep a small architectural checklist in `docs/ARCHITECTURE_CHECKLIST.md` that PR reviewers use. + +## 19. Enforcement +- Add a CI lint rule to fail builds on core -> ui imports. +- Add tests that assert UIs expose `dispose()` and that calling `initialize*UI` twice does not create duplicate IDs. + +--- +This file is authoritative. Follow it to prevent regressions and circular rework. + +## Logging & Debugging Architecture + +### Ring Buffer Logging System + +AcoustSee uses a unified **ring buffer logging system** (`utils/core-logger.js`) that consolidates all diagnostic output into a single, memory-efficient stream. This replaces traditional multi-stream logging and provides both in-memory and persistent storage. + +**Key Features:** +- **Memory-Efficient**: Fixed circular buffer (default 2000 entries) prevents unbounded memory growth +- **Unified Stream**: All log sources feed into one output, eliminating synchronization issues +- **JSON-Serializable**: All entries JSON-serializable for export and analysis +- **Developer-Friendly**: Real-time in-panel viewing with filtering and search +- **Performance-Conscious**: Minimal overhead (<5%) on core pipelines + +### Log Levels + +AcoughtSee defines four log levels, controllable at runtime via URL parameter or programmatically: + +| Level | Purpose | Use Case | Sampling | +|--------|---------|----------|----------| +| ERROR | Critical failures that impede functionality | Worker crashes, IndexedDB errors, auth failures | Always logged | +| WARN | Conditions that degrade quality or performance | Timeouts, fallbacks, resource exhaustion | Always logged | +| INFO | State transitions and significant events | Boot complete, mode switches, synth selections | Always logged | +| DEBUG | Detailed diagnostic data for troubleshooting | Frame timing, grid aggregation steps, worker init | **Sampled (1%)** to prevent log spam | + +**URL Control:** +``` +http://localhost:8000/?logLevel=DEBUG # Verbose (includes 1% DEBUG sampling) +http://localhost:8000/?logLevel=INFO # Standard (INFO, WARN, ERROR only) +http://localhost:8000/?logLevel=WARN # Quiet (WARN, ERROR only) +http://localhost:8000/?logLevel=ERROR # Silent (ERROR only) +``` + +### Structured Logging API + +All modules use `structuredLog()` from `utils/logging.js` or `utils/worker-logger.js` (for Web Workers): + +```javascript +import { structuredLog } from '../utils/logging.js'; + +// Simple message +structuredLog('INFO', 'my-module', { message: 'Boot complete' }); + +// With metadata +structuredLog('DEBUG', 'motion-handler', { + message: 'Motion detected', + regionCount: 64, + intensity: 0.75 +}); + +// With stack trace (for errors) +structuredLog('ERROR', 'audio-processor', { + message: 'Oscillator failed', + errorCode: 'OSC_INIT_FAIL' +}, /* addStack= */ true); + +// With sampling (for high-frequency events) +if (Math.random() < 0.01) { // 1% sampling + structuredLog('DEBUG', 'frame-processor', { + message: 'Frame processed', + fps: 29.5 + }); +} +``` + +### Worker-Safe Logging + +Web Workers cannot access `window.indexedDB` or the DOM.

This engine is **not** a monolithic controller; rather, it is a lightweight coordinator that enforces a clean, one-way data flow and decouples all major subsystems. + +### Key Files & Concepts + +1. **`engine.js` (The Engine):** + * **Responsibilities:** + * Holds the single, authoritative application `state` object. + * Provides the central `dispatch` method for queueing all actions. + * Manages a registry of `command handlers` that contain the actual business logic. + * Notifies all subsystems of state changes via the `onStateChange` listener. + * **Pattern:** This implements a standard **Redux-like, unidirectional data flow.** + +2. **`state.js` (The State Object):** + * **Responsibilities:** + * Defines the default shape of the application's entire state. + * This state object must be **fully JSON serializable**. It contains settings, flags, and data, but **no functions, class instances, or live browser objects** (like `MediaStream`). This "state hygiene" is critical for stability and debugging. + +3. **`commands/` (The Command Handlers):** + * **Responsibilities:** + * This directory contains all the application's business logic, organized into modular files (e.g., `media-commands.js`, `settings-commands.js`). + * Each file exports a `register...Commands(engine)` function, which is called at startup in `main.js`. + * Inside, individual command handlers are registered with the engine (e.g., `engine.registerCommandHandler('startProcessing', ...)`). + * **Pattern:** This is an implementation of the **Command Pattern**. It cleanly separates the "what to do" (the dispatched command) from the "how to do it" (the handler logic). + +4. **`context.js` (Dependency Injection and Legacy Bridge):** + * **Responsibilities:** + * Provides a simple mechanism for **Dependency Injection** (DI). For example, it holds a reference to the global `DOM` object. + * **Legacy Note:** This file contains older patterns like `getDispatchEvent()`. New code should **not** use these. Instead, the `engine` instance should be passed directly to any function that needs it during initialization. + +## The Unidirectional Data Flow + +Understanding this flow is the key to understanding the entire application. + +1. **Action:** The **UI** (or another subsystem) calls `engine.dispatch('someCommand', { payload })`. This is the *only* way to initiate a change in the application. + +2. **Command Handling:** The **Engine** finds the registered `command handler` for `'someCommand'` and executes it. + +3. **State Mutation:** The **Command Handler** contains the logic to perform the action.

No errors. Let me create a summary of all the changes made: + +## Summary + +I've fixed the **critical audio pipeline bug** that was preventing all synth engines from producing sound. The issue had two parts: + +### Part 1: Oscillator Pool Pre-Connection Bug ✅ +**Problem**: The oscillator pool was creating `{osc, gain, panner}` objects and immediately connecting them (`osc.connect(gain)`, `gain.connect(panner)`) and starting them (`osc.start()`). This violated Web Audio API constraints: +- **OscillatorNode.start() can only be called once** - synths couldn't start already-started oscillators +- Pre-connecting prevented synths from inserting filters or custom routing + +**Solution**: Modified all 4 pool functions to create unconnected, unstarted oscillators: +- `resizeOscillatorPool()` - Initial pool creation +- `getOscillator()` - Fallback when pool empty +- `releaseOscillator()` - Recycling used oscillators +- `playCues()` refill logic - Mid-session replenishment + +### Part 2: Missing Audio Routing ✅ +**Problem**: Synth engines never connected to `masterGain` (the volume-controlled output node): +- fm-synthesis.js - Set oscillator properties but never called `panner.connect(masterGain)` or `osc.start()` +- sawtooth-pad.js - Connected `osc -> filter -> gain` but never connected to panner/masterGain or started osc +- strings.js - Connected directly to `ac.destination` (bypassing volume control), causing loud uncontrolled output + +**Solution**: +- **fm-synthesis.js**: Added connection chain `osc.connect(gain) -> gain.connect(panner) -> panner.connect(masterGain)` and `osc.start()` for both carrier and harmonic oscillators +- **sawtooth-pad.js**: Added `gain.connect(panner) -> panner.connect(masterGain)` and `osc.start()` after filter connection +- **strings.js**: Changed output from `ac.destination` to `masterGain` for proper volume control + +### Result +All synth engines should now: +1. ✅ Receive clean, unconnected, unstarted oscillators from the pool +2. ✅ Connect them with custom routing (filters, effects) +3. ✅ Connect to `masterGain` for volume-controlled output +4. ✅ Start oscillators when ready +5. ✅ Produce audible sound + +**Ready for testing!** 🎵 \ No newline at end of file diff --git a/future/web/docs/BATTERY-OPTIMIZED_INGEST.md b/future/web/docs/BATTERY-OPTIMIZED_INGEST.md new file mode 100644 index 00000000..5d3e7c1c --- /dev/null +++ b/future/web/docs/BATTERY-OPTIMIZED_INGEST.md @@ -0,0 +1,33 @@ +## ✅ Battery-Optimized Ingest System Complete + +### 🔋 **Performance Optimizations** +- **Eliminated JSON.stringify overhead** -
