AudioDrop

About

AudioDrop is a browser-based audio tool that separates stems (vocals, drums, bass, other), converts formats, detects BPM and changes speed and pitch. It runs on Rust compiled to WebAssembly with WebGPU, and nothing is uploaded because the models run client-side. The author notes separation quality trails the best server-side models and that Safari WebGPU support and memory use on long files are rough.
