Your MIDI is ready
Your audio never uploads. Conversion runs entirely in your own browser. The file stays on your device.
BEST FOR
A clear, single melody
This local audio to MIDI converter follows the strongest audible pitch in the recording. A solo voice, piano line, guitar lead, or other isolated melody is the intended use.
KNOWN BOUNDARY
Full mixes need cleanup
Overlapping instruments, dense chords, drums, and noisy recordings can produce an incomplete melody. For a full arrangement, isolate a stem first, then refine the resulting MIDI in your DAW.
FAQ
Audio to MIDI, without an account
Is this an audio to MIDI converter or an MP3 to MIDI converter?
Both. MP3 is one accepted input, alongside WAV, M4A, OGG, FLAC, and WMA. The output is a standard MIDI file.
Can I use voice to MIDI?
Yes. A clear, sustained vocal melody is a suitable input. Keep the voice prominent and avoid backing instruments when possible.
Does this convert MIDI to MP3 or MP3 to sheet music?
No. This page is for audio to MIDI. Use the downloaded MIDI in a DAW or notation app if you need audio rendering or sheet music.
Why might the MIDI need editing?
Audio recordings contain timbre, noise, overlapping notes, and effects that a single melody track cannot represent exactly. The downloaded MIDI is an editable starting point.
