Frequently asked questions
Convert MP3 file to MIDI: how do I download the result?
Choose your file, select Convert to MIDI, then use Download MIDI when conversion finishes.
Can I convert MP3 into MIDI without uploading my recording?
Yes, audio processing and MIDI creation run in your browser, and the recording is not sent to a server.
Will every note be correct?
No, our chord and bass tests produced extra or fragmented notes, so review the MIDI before using it.
How do I convert WAV to MIDI?
Choose a WAV file, select Convert to MIDI, then download the result. Our PCM WAV sample converted successfully in Edge on Windows, but produced extra notes that needed correction.
Which formats have passed an audio to MIDI test?
MP3, WAV, M4A, FLAC, OGG, AAC samples each converted and produced a downloadable MIDI file in our Edge on Windows test.
