Audio to MIDI FAQ
Can you convert any audio to MIDI?
Yes, our tool can process any audio file. However, results vary based on the source material. Monophonic audio (single melody lines, vocals) converts most accurately. Polyphonic audio (full mixes with multiple instruments) is more challenging but can still produce useful MIDI data.
What's the difference between audio and MIDI?
Audio files (MP3, WAV) contain actual recorded sound waves - the vibrations captured by a microphone. MIDI files contain musical instructions (which note to play, when, how hard) but no actual sound. MIDI can be edited, transposed, and played with any instrument.
How accurate is the audio to MIDI conversion?
Accuracy depends on the audio source. Clean, isolated melodies convert with 90%+ accuracy. Complex mixes with drums, bass, and multiple instruments will have lower accuracy. For best results, use audio with clear melodic content.
Is the audio to MIDI converter really free?
Yes, completely free with no limits! All processing happens locally in your browser. We don't require sign-up, and there are no hidden fees or premium features.
