How to convert WAV to MIDI
Inspect the detected notes
After conversion, check each note's pitch, start time, duration, and velocity. Missing or extra notes can occur, especially when several instruments overlap.
Download the MIDI
Save the .mid file and open it in music software to edit the notes or assign an instrument. MIDI does not contain the original WAV sound.

GOOD TO KNOW
WAV to MIDI FAQ
Can I convert WAV into MIDI directly?
Yes. Choose a WAV file here and convert it in your browser. There is no MP3 step. The download is a .mid file containing detected notes.
What do I get when I turn WAV into MIDI?
You get estimated note pitches, start times, durations, and velocities. The MIDI file does not preserve the original recording's sound.
Does a WAV file guarantee correct notes?
No. Transcription can miss notes or add extra ones. Listen to the recording and inspect the note list before editing or using the MIDI.
Can I choose a different file type?
Yes. The same converter accepts the audio and video formats listed above. A video needs a decodable audio track; the picture is not analyzed.
What does the 120 BPM label mean?
It is the exported MIDI file's timing base. This page does not detect the recording's tempo.
Is my WAV uploaded?
No. This page decodes and transcribes the file on your device. It is not sent to an online conversion service.
