From One Upload to the Files You Need
Music Demixer separates a recording into useful parts, then turns the part you choose into files for practice, arranging, production, or notation. Start with a full song, a separated stem, or a solo recording.
Stem Separation
Split a song into six stems: vocals, drums, bass, piano, guitar, and Other. Preview and rebalance the parts, download MP3, Opus, or 16-bit WAV files, or use an available action to continue from a selected stem. If the action you want is unavailable, download the stem and upload it to the next task.
Sheet Music
Create a piano sheet music draft with a PDF for reading and editable MusicXML for notation work in Dorico, MuseScore Studio, Finale, Sibelius, or another compatible editor. AI-detected notes, rhythm, and layout may need cleanup.
MIDI
Turn one selected part into editable MIDI, or choose Multi-Track MIDI & Score for a full arrangement. Import the files into your DAW for editing, arranging, and instrument changes.
Vocal Tools
Separate lead and backing vocals, try Duet Vocals (Beta), or use Karaoke & Lyrics for lyrics, vocal MIDI, and vocal sheet music. Full-song Karaoke jobs also add lead-vocal reference and lead-removed backing audio.
Guitar Tab
Create an editable Guitar Tab draft in the tuning you choose. Open the .gp5 file in Guitar Pro, MuseScore Studio, TuxGuitar, Soundslice, GoPlayAlong, or compatible software. Full-song jobs also include Guitar and Backing track audio. Guitar Tab is Beta and may need editing.
Drum Kit
Isolate the complete drum layer, split kick, snare, toms, and cymbals, or create editable Drum MIDI for your DAW. Drum transcription also includes PDF and MusicXML score drafts.
