MP3 to MIDI, With the Audio Kept at Home

Field notes

The page accepts MP3 or WAV input and exposes the parts of melody detection that users can actually tune: a −45 dB silence threshold, a 65–1200 Hz pitch range, a 90 ms minimum note length, tempo, and grid quantization. It presents the output as a downloadable .mid file. The site says processing happens locally in the browser, with no upload, account, or watermark, and identifies clear single-note melodies as its best-fit material.
