StemTab separates vocals and accompaniment from a recording and drafts an editable score you can correct and export. Upload a song or the audio from a video and it splits the mix into vocals, guitar, bass, drums, piano and more, then uses automatic transcription to turn the notes into an editable MIDI and MusicXML score draft, with wave and score playback locked to the same position so you can check each bar as you listen. Export audio stems, printable PDF scores, MusicXML, MIDI and StemTab project files for practice or further production. The web workbench runs in the browser with cloud processing, and iPhone and iPad apps handle projects on-device with no account needed. Each verified email gets a one-time five-minute free preview on the web, and paid export is billed by processing minutes with no subscription and no expiry. It suits musicians, students and producers who need isolated tracks or a readable score from a finished recording.
