Helenalizer

Helenalizer turns audio into responsive, real-time visuals you can tweak live through a GUI. It’s written in C++17 and built with CMake. It is just an audio visualizer.

It’s built around:

• SFML for windowing/graphics/audio I/O
• TGUI for the interface layer
• OpenGL for rendering

What the app does (high level)

• Captures audio
• Processes audio in chunks, extracting frequency/energy information suitable for reactive visuals (e.g., spectrum-style bars)
• Renders visuals in real time while you interact with settings via GUI
• Supports asset-driven visuals (models/textures). A few small third‑party libraries are vendored in libs/ to keep integration straightforward.

Libraries used

Main dependencies

• SFML 3.0.2
• TGUI 1.11
• OpenGL

Vendored in libs/

• miniaudio
• nlohmann/json
• stb
• tinygltf

Build & run (CLion / CMake workflow)

1. Install SFML 3.0.2 and TGUI 1.11 on your system.
2. Open the project in CLion.
3. Ensure CMake config can find SFML/TGUI (you may need to adjust the library locations in the project’s CMake configuration).
4. Build and run from CLion.
