Frequently Asked Questions
Will it work in my browser?
Music Demixer works best on modern computers with up-to-date browsers. We run a quick compatibility check and choose the safest mode. If you need help, visit Support.
What audio formats are supported?
MP3, WAV, FLAC, M4A/AAC, OGG, AIFF, and most common formats. If something needs conversion, the app handles it automatically.
How does privacy work?
Private by default — most processing runs in your browser. Some tools may run briefly on our service to generate results, and files are not stored.
Is there a free plan?
We offer a 3-day free trial with full access. After the trial, you can keep Pro or cancel anytime from your account page. Card required to start the trial.
How do I convert MP3 audio into a MIDI file?
Upload MP3/WAV, choose MIDI output, run transcription, then download the .mid file for DAW editing.
Can melodic vocals be converted to MIDI notes?
Yes, sometimes. Melodic vocals can map well, but vibrato and background instruments reduce precision. Isolation improves results.
Why does exported MIDI feel different from the original song?
MIDI captures note events, not full audio nuance. Timing, articulation, and overlap may need editing in 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.
Convert Audio to MIDI
Single-instrument MIDI or Multi-Track MIDI (all instruments).
MP3 to MIDI Converter for Single-Part Transcription
Convert MP3 to MIDI directly in your browser and export DAW-ready files for editing. It is optimized for broad audio to MIDI use with single-part workflows.
Best inputs for clean MIDI
Single instruments and clear attacks produce the cleanest notes. Dense mixes can still work, but usually need more cleanup in your DAW.
Use cases
- Producer workflow: sketch parts fast, then quantize and layer in your DAW.
- Practice workflow: convert a line and slow it down for study.
- Remix workflow: pull a melody/bass contour and rebuild instrumentation.
Instrument paths
Piano HD works well for hand and pedal detail. Guitar/bass and vocal lines can produce useful MIDI when source audio is clean and isolated.
Improve results on complex songs
Use stem separation online before conversion when the target part is buried. For full-song multi-instrument output, use multi-track MIDI.
