Convert a WAV file into editable MIDI.

How to convert WAV into MIDI without uploading the recording

Select the WAV file in the converter above. The browser decodes it, reduces it to one audio channel at 22,050 Hz, then runs note transcription on this device. When the result appears, use Download .mid. The downloaded MIDI contains note events rather than the original waveform, so it can be moved, shortened, quantized, or assigned to another instrument in a MIDI editor.

WAV to MIDI converter, WAV to MIDI file converter, and the other search phrases

“WAV to MIDI converter,” “WAV to MIDI file converter,” “convert WAV file to MIDI,” “convert WAV to MIDI,” and “convert WAV into MIDI” all lead to the same operation on this page. One WAV goes in; one editable .mid file comes out. There is no separate page or hidden workflow for a different wording.

What the comparison test tells you

The test cards above come from one generated four-second phrase saved once as WAV and once as 128 kbps MP3. Both files were processed with this page’s note threshold of 0.25, onset threshold of 0.25, and minimum note length of five frames. The result records note count, long and short detections, missed source pitches, and the downloaded MIDI byte count. Those values are kept visible so the format choice can be judged from the actual run rather than a promise.

When the MIDI needs editing

A MIDI file is an interpretation of the recording, not a copy of its sound. If a chord creates extra notes or a soft attack disappears, open the .mid file in your editor and inspect the note starts before quantizing. For a dense mix, isolate the part you need and run that shorter WAV instead of asking the transcription to separate every instrument at once.
