SoundToMIDI

SoundToMIDI runs in your browser and turns audio files into editable MIDI without uploading your audio or needing an account. It accepts MP3, WAV, FLAC, M4A, OGG and compatible MP4 files and produces a Raw MIDI file you can download for use in DAWs or notation software.

The interface shows a piano-roll view, note statistics and tempo information, and lets you listen to the original audio alongside the Raw and a cleaned MIDI version. If you like the cleaned result you can buy that cleaned download for a one-time $2.99 charge.

There are cleanup controls aimed at melody, bass or piano, each adjustable across several strengths. Clear melodies and isolated instruments tend to convert well; dense mixes can generate extra or missed notes and may still need manual editing.
