Stemfold

Local audio stem separation for macOS and Windows

Stemfold

Turn any song into separate vocals, drums, bass, and instruments, detect its BPM automatically, and generate a click track, entirely on your computer.

Stemfold is a native desktop app for macOS and Windows. It uses Demucs, widely regarded as one of the best model families for high-quality music source separation, automatically detects the song's BPM to generate a click track, and keeps every recording private by processing it locally.
