Editorial interest 82/100 Selection signal · not a rating of the site

A browser-based AI tool that separates songs into vocals, drums, bass, and other stems without uploading the audio.

Landing page captured for the 2026-09-04 issue.

Field notes

The page accepts MP3, WAV, FLAC, M4A, OGG, and AAC files up to 50 MB or 10 minutes, then applies a Demucs v4 model inside the browser. The first separation downloads a roughly 170 MB model and caches it; later runs can work offline. WebGPU is used where available, while Safari and Firefox are described as falling back to WebAssembly CPU processing.
