When audio-to-MIDI is useful
Use the result for piano notation, practice review, arranging, or detailed note editing. The output follows the uploaded performance and may still need musical review.
Record for a cleaner result
Keep the piano louder than background sounds, avoid clipping, and reduce room echo where possible. A direct recording or a close microphone usually gives clearer note boundaries.
Choose the sustain behavior
Use With sustain for connected playing and pedal-heavy recordings. Use Without sustain when you need shorter note boundaries for detailed editing.
Common questions
Which audio formats can I upload?
WAV, MP3, FLAC, M4A, AAC, OGG, and WEBM are supported, up to 80MB per file.
Does it work with a full band recording?
The service is designed for piano-focused recordings. Other instruments, vocals, and strong background noise can reduce transcription quality.
Is the MIDI guaranteed to be exact?
No. Recording quality, room echo, performance complexity, and instrument balance can affect the result.
