FILE SUPPORT
Audio to MIDI, without format juggling

MP3 to MIDI FAQ
Can I use WAV to MIDI here?
Yes. WAV, MP3, FLAC, OGG, M4A, AAC, AIFF, and Opus use the same conversion flow. Choose the file and download the detected MIDI notes.
Can this MIDI converter read video files?
Yes, if the video contains an audio track that this computer can decode. The converter reads the sound, not the video frames.
Will MIDI preserve the original sound?
No. MIDI contains detected pitches, note timing, and velocity. Choose an instrument in your music software to hear those notes.
What does the 120 BPM label mean?
It is the MIDI file's timing base, used to preserve note timestamps. This page does not estimate your song's tempo.
