WAV to MIDI, straight from your bounce

WAV files are what your DAW bounces and what sample packs ship as, and they are the best thing you can feed a transcription model. Upload a WAV (or AIFF or FLAC) and get back MIDI that drops into the same project it came from.

How to convert WAV to MIDI

  1. 1

    Bounce or pick a WAV

    Any sample rate and bit depth. Stereo or mono, a full mix or a single stem, up to 10 minutes and 100 MB.

  2. 2

    Tell it what is in the file

    For a full mix, choose the stems to transcribe. For a single instrument, turn the rest off to skip separation.

  3. 3

    Match your project

    Keep the detected tempo map, or type in your project tempo. Choose the PPQ your DAW prefers.

  4. 4

    Drag the MIDI into your DAW

    Export a .mid file with one track per instrument and line it up at bar 1.

Why WAV converts best

A WAV file is uncompressed, so the sharp start of every note, the thing a transcription model listens for most, is intact. That means tighter note starts, fewer phantom notes from compression artefacts and better velocity estimates. AIFF and FLAC are lossless too and convert just as well.

If you are converting your own music, export the stems from your DAW rather than the master. A dry, single-instrument WAV is the easiest possible case and skips the separation step entirely.

Lining the MIDI up with your session

The most annoying thing about most audio to MIDI tools is dragging the result into your project and finding it does not line up. Midify gives you the options to prevent that:

  • Tempo: the detected tempo map, a single average BPM, or the BPM you type in. It never silently exports at 120.
  • Start: shift the first downbeat to bar 1 (with a pick-up bar if the music starts early), or keep the original timing to the millisecond.
  • Resolution: 96, 192, 384, 480 or 960 PPQ.
  • Layout: one track per instrument, one merged track, or one file per stem in a zip.

Loops and one-shots

Short WAV loops are perfect for quick mode, which runs the transcription in your browser. Nothing is uploaded, it is free and unlimited, and the MIDI opens in the same editor. Use the server for full songs and anything that needs separating first.

WAV to MIDI: questions people ask

Is WAV to MIDI more accurate than MP3 to MIDI?

Usually a little. Lossless audio keeps the note attacks intact, so timing and velocities come out tighter. A high-bitrate MP3 is close; a low-bitrate one is noticeably worse.

Can I convert a WAV loop without uploading it?

Yes. Quick mode runs the transcription in your browser, so the file never leaves your device. It suits loops, single instruments and short clips.

What sample rates are supported?

All the common ones, from 44.1 kHz to 192 kHz, at 16, 24 or 32-bit. The file is resampled internally, so you do not need to convert it first.

Can I convert AIFF or FLAC files?

Yes. AIFF, FLAC, MP3, M4A and OGG all work the same way as WAV.
