6-stem separation with mix preview
Separate a full song into six stems: vocals, drums, bass, piano, guitar, and Other. The stem page also shows preview and rebalance controls before export.
Overview
Music Demixer is an online audio-to-music tool that turns uploaded songs into stems, MIDI, and sheet-music drafts. The site positions piano and drum transcription as the most specialized workflows, while other instruments can be processed as editable drafts.
It supports stem separation, piano sheet music, Drum MIDI, drum kit breakdowns, and exportable audio files for practice or production. The product is designed for users who want to upload a track once, preview the result, and download files in formats that fit score editing or DAW-based work.
Features
Audio-to-score and MIDI workflows
Generate piano sheet music, Drum MIDI, and editable drafts from uploaded audio. The site distinguishes specialized transcription for piano and drums from draft-level output for guitar, bass, vocals, and Other.
Drum extraction and kit-piece separation
Use the drum workflow to isolate drums, split them into kit pieces, or create Drum MIDI and drum notation drafts. The site exposes 4-, 5-, and 6-piece kit splits, including kick, snare, toms, hi-hat, ride, and crash options.
Instrument-specific transcription paths
Choose between piano, drums, guitar, bass, vocals, and Other when creating MIDI or sheet-music outputs. Piano and drums are described as the most specialized paths, while the other parts are treated as drafts that may need cleanup.
Broad input and export support
Upload MP3, Opus, or WAV for stem downloads, and the FAQ lists MP3, WAV, FLAC, M4A/AAC, OGG, AIFF, and other common formats. The site says conversion is handled automatically when needed.
Built-in workflow help
Access a help chat called Ask Music Demixer for workflow guidance and file questions while you work.
