A macOS Apple Silicon app that uses Demucs v4 to separate songs into vocals, drums, bass, loops, and other stems.

Landing page captured for the 2026-09-15 issue.

Field notes

The tool separates music into named components using Demucs v4 and presents the result as 24-bit WAV output processed on the Mac rather than uploaded to a server. Its browser playground exposes a concrete test case—an Electronic Studio Jam at 126 BPM and 8A—and offers channel-by-channel playback. The page also claims Metal optimization across Apple M1, M2, M3, and M4 chips, plus automatic Camelot key classification for DJ workflows.
