FAQ
What types of audio work best?
Single instrument recordings (piano, guitar, voice, flute) give the best results. Complex mixes with drums may produce extra noise.
How accurate is the transcription?
For single-instrument recordings, accuracy is typically 85-95%. For complex polyphonic music, expect 60-80%.
Is my audio uploaded to a server?
No. All processing happens in your browser using TensorFlow.js. Your audio never leaves your device.
What is MIDI?
MIDI is a universal format for musical notes. It can be opened in any DAW (GarageBand, Ableton, FL Studio) or notation software (MuseScore, Sibelius).
Can I transcribe a full song?
Yes, but for best results, isolate the instrument you want to transcribe. Use our Vocal Remover tool to separate vocals from instruments first.
What formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC — any format your browser can decode.
We can — and it's free! Just send us a quick message with your idea. If you'd like to discuss it in detail, leave your email and we'll get back to you. You can stay anonymous.
