Audio spectrum visualizer
Demo: dzwi.ga/dft/
Visualizes audio frequencies with DFT (Discrete Fourier Transform).
This app uses Neighbour Components (NC) method.
Underlaying algorithm is Sb-SDFT Single bin - sliding Discrete Fourier Transform.
Sliding DFT is calculated on the CPU using fixed-point integer math.
Program compilation
cargo build --release
cargo install cargo-make
Windows: cargo make release
Linux: cargo make releasel
Todo
- Organize code (less mutexes, separate crates)
- remove
cargo make - compute shaders instead of CPU DFT
- remove statics with unsafe - use only
Arc
Running
Windows: cargo run --release -- -i stereo
Linux: Make sure your default input device is 'Stereo Mix' - desktop audio monitor/loopback.
Then: cargo run --release
Name
Repo name is bad. Wanted to name it chromatone (similar to colorchord), but it's already taken: https://github.com/chromatone
Wasm compilation
- download https://github.com/WebAssembly/binaryen/releases/latest
- Linux:
wget https://github.com/WebAssembly/binaryen/releases/download/version_111/binaryen-version_111-x86_64-linux.tar.gz -O - | tar -zxvf - mv binaryen-version_111 bin/binaryencargo install cargo-makecargo install wasm-bindgen-clinpm install tersercargo make rbo
Shader compilation
Unnecessary, because of new .wgsl
Old SPIR-V compilation:
