What does Music Demixer do?
Music Demixer is an online tool that turns an audio file — MP3, WAV, FLAC, or similar — into multiple useful outputs at once. Upload a full song, and you can get separated stems (vocals, drums, bass, piano, guitar, and Other), editable piano sheet music drafts, DAW-ready MIDI files, and drum kit breakdowns. The tool handles all processing on its cloud servers, so you don't need special software or a powerful computer.
The tool works in a clear three-step process: upload your audio, pick what you want to create (stems, sheet music, MIDI, or a drum kit mix), and wait for the job to finish. Piano and drum transcription use specialized AI paths that produce more accurate results — hands and pedals for piano, individual kit pieces for drums. Guitar, bass, vocals, and other parts come out as editable drafts that may need some note cleanup. You can preview separated stems before downloading, and exports include MP3, Opus, WAV for audio, and MusicXML, PDF, or MIDI for notation and DAW work.
This is for musicians, producers, and content creators who want to study a song's arrangement, create covers, remix tracks, or transcribe parts without doing it by ear. A music teacher pulling piano notation from a recording, a producer isolating a vocal for a remix, or a drummer extracting a MIDI pattern from a live track all fit the use case. The free trial gives you 5 full-quality jobs up to 5 minutes each, no credit card required. After that, it's $9.99/month.
