SoundToMIDI

SoundToMIDI is a browser-based audio-to-MIDI converter for musicians, producers, songwriters, arrangers, educators, and students. It accepts MP3, WAV, FLAC, M4A, OGG, AAC, and compatible MP4 files, then performs transcription on the user's device without uploading the source audio or requiring an account. The result includes a piano-roll view, note statistics, and a Raw MIDI file that users can download for free. They can compare the original audio with Raw and Cleaned MIDI before deciding whether to buy the optional cleaned download for a one-time $2.99 charge. Cleanup controls can target melody, bass, or piano. Clear melodies and isolated instruments work best, while dense mixes can still need manual editing.
