Audio to Sheet Music
Turn a recording into notation you can actually read. Upload audio, and an AI transcription pipeline engraves the notes on a staff — with a detected key signature — ready to print, save as PDF, or open in your notation app.

What does converting audio to sheet music involve?
Going from sound to score is really two problems. First, transcription: a neural network listens to the waveform and decides which pitches sound at each moment, where each note starts and stops, and how loud it is. Second, notation: those raw note events have to be quantized to a rhythmic grid, given a key signature, split across treble and bass staves, and engraved into readable music — the part most converters skip.
This tool does both. The transcription model is polyphonic, so chords and accompaniment survive rather than collapsing into a single line. The notation pass then detects the key by weighing every note's length and strength, snaps timing to the grid, and renders the result right on the page.
By convention, music this side of a human editor is a draft: expect to correct occasional notes, especially from reverberant or busy recordings. The point is that you start from a score that is mostly right instead of an empty staff — and the MusicXML export drops that draft straight into MuseScore or any other editor.
Audio to sheet music features
Score rendered on the page
No downloads needed to see the result — the engraved staff appears right below your audio, seconds after transcription finishes.
Key signature, detected
The pipeline analyses the whole performance to choose the key, so the score reads like music instead of a wall of accidentals.
Grand staff layout
Low notes to the bass clef, high notes to the treble — the layout keyboard players and arrangers expect.
Print & save as PDF
One click opens a clean, white, print-ready score — save as PDF from the print dialog or send it to paper.
MusicXML export
The universal notation format: open your draft in MuseScore, Sibelius, Finale or Dorico and edit anything.
MIDI included
Alongside the score you get a standard MIDI file with the original, unquantized performance for DAW work.
What lands on the score
Sheet music is more than note heads. This is what the notation pass writes into every score, and what it deliberately leaves for you:
| Key signature | Detected automatically | Weighted by note length and strength, so ghost notes do not flip the key. |
| Treble + bass staves | Split at middle C | Standard grand-staff convention; cross-staff voices stay on their side. |
| Tempo mark | Estimated from the audio | Beat tracking sets the metronome mark the score is quantized against. |
| Time signature | Notated in 4/4 | Meter estimation from raw audio is unreliable, so the grid is honest 4/4 — change it in one click in your notation editor. |
| Dynamics & articulation | Left to you | Hairpins, slurs and pedal marks are editorial judgements — no AI writes them well yet, and we prefer honest blanks to guesses. |

Why people convert audio to sheet music
Learning a song with no published score
Covers, live versions, unreleased tracks — if it exists as audio, you can get a readable draft of it.
Archiving improvisations
The take you loved last night becomes a score you can still play next year.
Preparing parts for other musicians
Hand a singer or string player actual notation instead of asking them to learn from the recording.
Study and analysis
Seeing the harmony on a staff beats scrubbing a waveform when you want to understand what a piece is doing.
How audio becomes sheet music
1. Upload any audio
MP3, WAV, FLAC, AIFF, OGG or M4A, up to 10 minutes on the free tier. The cleaner the recording, the cleaner the score.
2. Transcribe, then engrave
The AI detects every note polyphonically; the notation pass removes overtone ghosts, detects the key, quantizes the rhythm and engraves the staff.
3. Print, save, or keep editing
Read the score on the page, print or save it as PDF, and download MusicXML + MIDI to continue in your own tools.
Audio to sheet music FAQ
Can I convert audio to sheet music online free?
Signing up is free and comes with 10 credits; a conversion costs one credit and delivers the full result — engraved score, PDF printing, MusicXML and MIDI. No watermark, no 30-second preview cap.
How readable is the sheet music, honestly?
For clean solo-instrument recordings, very: detected key signature, sensible rhythms, both staves populated. For dense or reverberant mixes you will see occasional extra notes and odd rhythms — the draft is for correcting, not framing. We would rather tell you that here than let the first conversion tell you.
Which audio formats can I convert?
MP3, WAV, FLAC, AIFF, OGG and M4A. Lossless sources (WAV, FLAC, AIFF) transcribe slightly better than heavily compressed MP3s, because compression discards exactly the quiet inner voices a transcriber needs.
Does it write the correct key signature?
The key is detected from the whole performance, weighted by how long and how strongly each note sounds. On our benchmarks this correctly identifies the key where naive per-note analysis fails. Enharmonic spelling follows the detected key.
Why is the score in 4/4?
Estimating meter from raw audio is genuinely unreliable, and a wrongly guessed 3/4 reads worse than an honest default. The notes and their durations are correct regardless — changing the time signature is one click in MuseScore and the music re-bars itself.
Can I edit the sheet music?
Yes — download the MusicXML and open it in any notation editor: MuseScore (free), Sibelius, Finale, Dorico, Flat. Every note, rhythm and marking becomes fully editable there.
