A personal GUI + TUI music visualizer written in Rust.
I decided to write the visualizer because existing projects didn't suit me. Some too slow, some didn't have the visualizer I like, some take up too much cpu usage, etc.
This project also serves as my playground, so you'll see a lot of weird implementations in the source files.
New visualizers: TODO! Configuration changes: TODO!
Terminal and minifb mode have been moved to their own features. You'll need to
recompile with --features terminal and/or --features minifb to use them.
Coffeevis is built for and runs on Linux. Windows, MacOS and BSD support is not available.
Run cargo install coffeevis
To run coffeevis in a terminal, use:
cargo install coffeevis --features terminal
If for some reason you want to use minifb, use:
cargo install coffeevis --features minifb
Coffeevis does not remember settings and does not generate config files (feature won't be implemented unless requested).
To get around this, make a user script that runs coffeevis with flags
E.g:
#!/bin/bash
/path/to/coffeevis --fps 60 --no-auto-switch --size 40x40
Coffeevis supports temporary options at launch
| Option | Value (example) | Description |
|---|---|---|
| --minifb | opens window with minifb (coffeevis now runs with winit by default) | |
| --x11 | runs in X11 (Wayland is the default) | |
| --ascii --block --braille |
runs in the terminal | |
| --no-auto-switch | disables automatic visualizer switching | |
| --size | 80x80 | sets resolution in window mode |
| --scale | 2 | upscales in window mode |
| --fps | 60 | sets refresh rate |
| --resizable | allows resizing in window mode | |
| --max-con-size | 50x50 | sets maximum resolution in terminal mode |
| --vis | spectrum | launches coffeevis with the specified visualizer |
Upon launch coffeevis will grab your default audio source, use an audio
config tool to direct your desired source to coffeevis (e.g. pavucontrol).
On Wayland, coffeevis cannot set itself on top so you will have to rely on an external tool. For example, on KDE Plasma, you can use the window rules feature.
When input is quiet, the visualizer will try to amplify the input so that the visualizers don't become boring.
Coffeevis prints text directly to stdout, rendering may be heavy depending on your terminal.
A terminal with GPU-accelerated support is recommended (i.e Alacritty, Kitty, Wezterm, ...)
A maximum resolution is built into the console mode (default: 50x50). Coffeevis will render in the center of the screen if terminal dimensions are larger than the limit.
| Key | Description |
|---|---|
| Space | iterates forward through visualizers (wraps around) |
| b | iterates backward (wraps around) |
| Esc | exits |
| / | resets all settings |
| - / + | decreases/increases input volume |
| [ / ] | decreases/increases spectrum roughness |
| ; / ' | decreases/increases amount of samples into input (works for some wave-based visualizers only) |
| \ | toggles auto switching (default: ON, 8 seconds) |
| n | switches through sets of visualizers (wraps around) |
| Key | Description |
|---|---|
| . | toggles between ascii rendering, block rendering and braille rendering |
| 9 / 0 | decreases/increases maximum resolution |
| 7 / 8 | decreases/increases fps by 5 (default: 60) |
| 1 ... 6 | changes fps to 10 ... 60 respectively |
Please don't look at my code. No I'm not hiding anything in there it's all garbage code idk how to do gpu programming so it's all cpu code uh uhhh
