Preview uses a simple synth. MIDI contains notes, not the original sound.

How does this audio to MIDI converter work?

It detects one pitch at a time in your audio and groups it into editable notes. Noise, chords, vibrato, and overlapping instruments can cause missed or extra notes. Review the preview and refine the file in your music software.

Can I use it for voice to MIDI?

Yes, start with a clear solo vocal melody in a supported audio format. It follows sung pitch, not spoken words. Adjust the pitch range to your voice before converting.

Does it convert the whole file?

Accepted files are analyzed from beginning to end, including silence. The limit is 25 MB and 3 minutes per file. There is no daily conversion limit. Long files may take time on a phone.

What can I download?

A standard .mid file with one melody track. One file at a time: MP3, WAV, FLAC, OGG, M4A, MP4, MOV, MKV, or WebM. Video files must contain a decodable audio track; the first audio track is used. Encrypted media and unsupported codecs cannot be decoded. The decoder downloads on first use.
