What audio formats are supported?

How do I convert MP3 audio into MIDI files?
Upload MP3 or WAV from a song, stem, or solo recording, then run the MIDI workflow. You receive Original Timing MIDI for syncing with the recording and Beat-Aligned MIDI for editing against the detected score grid.
Can I start from a full song or a stem?
Yes. From a full song, choose the instrument you want and Music Demixer separates that part before transcription. Upload a stem or solo recording when you already have the isolated part. The MIDI is editable and may need cleanup.
Can melodic vocals be converted to MIDI notes?
Yes. Melodic vocals can become editable MIDI. Vibrato, doubles, and harmonies can produce notes that need correction after import.
Can guitar or bass be converted to MIDI?
Yes, guitar riffs and bass lines can become editable pitch drafts. Heavy distortion, overlapping notes, and complex articulation usually require cleanup after import.
Why does the MIDI draft sound simpler than the original audio?
MIDI captures note events, not the full texture of the recording. Timing, overlap, articulation, and voicing often need cleanup once you import the file into your DAW.
What audio can I upload for MIDI transcription?
Upload audio you're authorized to use. You're responsible for copyright and licensing compliance in your jurisdiction.
Can I use the output commercially?
Yes, if you own the rights to the input audio or have permission or a license, you can use the outputs commercially.
MIDI Files for Editing in Your DAW
Convert one musical part or a full arrangement into editable MIDI.
One part or Multi-Track
Choose an instrument when you want MIDI for that part, whether your input is a full song, a stem, or a solo recording. Choose Multi-Track when you want separate MIDI tracks for multiple instruments. See the Multi-Track MIDI & Score guide for its draft outputs and limitations.
Choose the MIDI you need
- Piano creates editable melodic MIDI for notes, chords, and timing.
- Drum MIDI captures rhythm and percussion patterns for editing in your DAW.
- Bass, vocals, guitar, and Other create editable note drafts for cleanup.
What the MIDI file gives you
Start from a full song, stem, or solo recording. The download is an editable MIDI file for Ableton Live, Logic Pro, FL Studio, GarageBand, Cubase, REAPER, or another DAW. Timing, note lengths, octave placement, overlap, and voicing can need adjustment. Choose Sheet Music for a PDF score and editable MusicXML.
