A real conversion. Play the audio below — the piano roll under it is the actual MIDI basic-pitch produced from this exact file. No cherry-picking.
Generated by running basic-pitch on this MP3 with default parameters. Note count includes harmonics — that's the real model output.
How Audio to MIDI works
1. Upload audio
Drop MP3, WAV, FLAC, AIFF, OGG, or M4A. Up to 10 minutes per file on free tier.
2. AI extracts MIDI
A neural pitch model identifies notes, onsets, and velocities. Stable across instruments and vocals.
3. Edit & export
Tune notes, quantize, choose key, and export as .mid or MusicXML — ready for any DAW.
FAQ
What's the difference between MIDI and MusicXML?
MIDI is a performance format — it captures notes, timing, and velocity but not visual notation. MusicXML is a notation format that describes how to render sheet music (beams, slurs, key signatures). AIFlowMusic exports both: use MIDI for DAW work, MusicXML for notation software like MuseScore, Sibelius, or Finale.
Why basic-pitch and not Onsets-and-Frames or MT3?
Basic-pitch (Spotify Research, 2022) is open-source, runs efficiently on Vercel's Fluid Compute, and handles both monophonic and polyphonic audio in one model. Onsets-and-Frames is piano-specific. MT3 is more accurate on certain instruments but roughly 10x slower and requires a GPU. For a free, instant-conversion tool, basic-pitch is the right tradeoff.
Can I extract chords from polyphonic audio?
Yes — basic-pitch detects polyphony, so chords arrive as simultaneous note-on events in the output MIDI. You can split them into individual notes or treat them as a chord block in your DAW. For best chord accuracy, use stems rather than full mixes.
How do I import the .mid into Ableton Live?
Drag the .mid file from Finder or Explorer into Ableton's Session view. It creates a new MIDI track with all notes preserved. Assign an instrument plugin (Operator, Wavetable, or any VST) to play the MIDI.
How do I import the .mid into Logic Pro?
File → Open and select the .mid. Logic creates a project with each MIDI channel as a track. Alternatively, drag the .mid into an existing project's tracks area.
What's the conversion latency for long files?
Conversion runs at roughly 8x real-time on Vercel's Node.js runtime — a 10-minute file takes about 75 seconds. Files over 5 minutes show a progress indicator. Creator and Producer plans run on prioritized workers.
Is the MIDI editable in MuseScore or Notion?
Yes. Both accept .mid files directly. For better notation results — correct key signatures and beam grouping — use the MusicXML export instead.
Does AIFlowMusic store my uploaded audio?
Uploaded audio is processed in memory and deleted within 24 hours. The resulting .mid stays in your account so you can re-download. Free tier processes but doesn't persist; Creator and Producer plans keep outputs for 30 days.
