Stem Separation / Auto-Transcription
Pull any song apart into its individual tracks — vocals, drums, bass and the rest — then turn them into MIDI, sheet music and Guitar Pro. All right inside your browser; nothing leaves your device.

Pick the stems you want, turn them into notes — then export to MIDI, to a Guitar Pro / MuseScore score, or to PDF. Transcription is automatic and approximate; a great starting point to refine in your software.
The separation happens entirely inside your browser tab. Your audio is never sent to a server — not ours, not anyone’s.
It uses your device’s own processing — so it works without our machines running, and stays free no matter how many people use it.
Solo, mute and balance each stem, then download any track as a WAV file to use in your own projects.
The engine separates a mix into vocals, drums, bass and a combined other track. Synths, saxophone and strings live inside other — isolating those individually isn’t something today’s in-browser models do reliably. For the fastest, highest-quality results, ask us about the desktop app.
