A native Rust implementation of HTDemucs v4 — state-of-the-art music source separation. Splits any song into individual stems (drums, bass, vocals, etc.) using GPU-accelerated inference via Burn.

Runs as a native CLI (Metal on macOS, Vulkan on Linux/Windows), entirely in the browser via WebAssembly + WebGPU, or as a DAW plugin (VST3/CLAP, macOS) — no server, no uploads, fully local.
