HOW IT WORKS
How WAV to MIDI Conversion Works
WAV stores recorded sound as an uncompressed waveform. MIDI stores musical instructions — which note, when to play it, how long, and how hard. To convert WAV to MIDI, the AI model analyzes the audio spectrum, detects note onsets and sustained pitches, and maps them to MIDI note events.
Unlike lossy formats like MP3, WAV retains full audio fidelity, which can lead to more accurate note detection. The AI processes the raw waveform data to identify fundamental frequencies, harmonics, and temporal patterns, then outputs a standard MIDI file you can use in any DAW, notation software, or virtual instrument.
GET THE BEST RESULTS
Tips for Better WAV to MIDI Conversion
- Use a clean recording with minimal background noise for best accuracy.
- Select the preset that matches your audio type (Piano, Voice, Guitar, etc.).
- Start with a short section (30-60 seconds) to test the quality.
- Raise sensitivity for quiet or delicate passages.
- Lower sensitivity if the conversion picks up too many extra notes.
- Increase minimum note length to filter out short artifacts.
