About
Built by Caly. One page, one job.
Hummingtomidi turns an audio file into an editable Standard MIDI file. You drop in an MP3, WAV, OGG, M4A, AAC or FLAC file and it writes out a .mid of the melody it hears — entirely inside your browser, with no upload, no account and nothing kept after you close the tab. It exists because converting one short melody should not mean signing up, waiting in a queue, or handing your audio to somebody else's server. It is deliberately small: one clear melody at a time, no batch mode, no history, no login.
