Audio to Sheet Music Converter: Turn Any Recording into a Score

To turn audio to sheet music, drop a recording on the converter below or record one in your browser. ToMIDI listens with Spotify's open-source Basic Pitch model, right on your device, and writes the notes it hears as real notation you can play back, fix and print. Choose the instrument first (piano, voice, guitar, bass or a solo melody) so the score gets the right staff, then check the key, meter and timing and print it, save it as a PDF, or export MusicXML, MIDI, PNG and SVG. It is free, there is no sign-up, and nothing is uploaded. One instrument, clearly recorded, gives the cleanest score.

Why Music Transcription by Ear Takes So Long

To transcribe music by hand you loop a few seconds, hum the line back, find each note on a keyboard, count the rhythm against a click and write it all down, bar after bar. A trained music transcriber is fast at it; for everyone else, one short song can eat an evening. An audio to sheet music converter does the listening and the first draft for you, so you start from a page of notes and fix what it got wrong.

  • Fast runs and chords blur together after the tenth replay.
  • Rhythm is the hard part: a note that is a little late is a sixteenth, or is it?
  • Working out the key and the time signature comes before any of it reads well.
  • Copying it neatly into notation software is a second job on its own.

Why Use ToMIDI as Your Audio to Sheet Music Converter

A music to sheet music converter that hears your recording, writes it down, and leaves you in charge of the result.

  • A staff for your instrument

    Piano writes a grand staff with both hands; Voice and Solo melody write one clean line; Guitar and Bass get the staff those players read. Pick it before you convert, or switch afterwards and the notes are read again for that instrument.

  • Your recording stays with you

    The Basic Pitch model runs inside your browser tab. Your audio is never uploaded, so rehearsal takes, lessons and unreleased songs stay private.

  • Key, meter and timing you control

    The converter detects the tempo and the key. Change the key, choose 4/4, 3/4, 2/4 or 6/8, pick a 1/8 or 1/16 grid with or without triplets and move the bar lines for a pickup; the score redraws as you click.

  • Hear it, then fix it

    Play the score with a cursor that follows the bar, compare it with your recording, then move a wrong note by a semitone or an octave, delete a stray one and undo any change.

  • Parts for transposing instruments

    Write the transcription for B-flat clarinet, trumpet or tenor sax, E-flat alto or baritone sax, F horn or guitar, key signature included, or shift it up to an octave for a singer.

  • Print it, or keep working

    Print the score or save it as a PDF with your browser's print dialog, export PNG and SVG for a worksheet, or download MusicXML for MuseScore, Sibelius, Finale or Dorico and MIDI for your DAW.

How to Convert Audio to Sheet Music in Four Steps

Whether you want to translate an MP3 to sheet music for a lesson or write down a melody you just sang, this is how to transcribe music with ToMIDI: no install, no account, and the whole job happens on the page you are reading.

  1. Drop an MP3, WAV or other audio file on the converter above to convert an MP3 into sheet music, record a take with your microphone, or open one of the samples to see how it works first. Already have a MIDI file? Use MIDI to sheet music instead.

  2. Pick Piano, Voice, Guitar, Bass or Solo melody. The preset tells the converter which staff to write and what kind of line to expect, so a sung melody is not spread across two staves.

  3. Basic Pitch takes it from MP3 to notes on your device, and you can watch them appear as it listens. Check the key, the time signature and the quantize grid, press play and follow the cursor, and fix any note that sounds wrong.

  4. Print the sheet music or save it as a PDF, export PNG or SVG, or download MusicXML and MIDI to keep editing in a notation app or a DAW.

Step 1 · Add your recording

What the Sheet Music Generator Does with Your Recording

Five things happen between the audio and the printed page in this AI sheet music generator, and you can steer every one of them.

An instrument preset decides the staff

A piano recording needs two staves, a singer needs one, and a bass line belongs in the bass clef. Choose Piano for a grand staff with the hands split, Voice or Solo melody for a single melodic line on one staff, and Guitar or Bass for those parts. The same engine runs underneath; the preset shapes how its notes are laid out and cleaned up, which is why picking the right one is the single biggest step toward a readable score.

Pick an Instrument

Notes from audio, heard on your device

Basic Pitch, Spotify's open source music transcription software, listens to the recording frame by frame and marks every pitch it hears with a start, an end and a loudness. ToMIDI runs it in your browser, drops very short blips and, for chordal instruments, quiet overtone ghosts above real notes, and turns the timing into beats from the detected tempo, so audio to music notes, or MP3 to music notes, becomes notes on a grid.

Transcribe Your Audio

Timing tidied into rhythm you can read

Nobody plays exactly on the beat, and a converter that wrote down every small push and drag would fill the page with ties and tiny rests. Choose a 1/8 or 1/16 grid, switch triplets on for swung or compound rhythms, set the meter and the pickup, and MP3 to notation turns into rhythm a player can read at sight.

Tidy the Rhythm

A sung melody, written for clarinet, sax or horn

Hum or sing a tune and give it to a B-flat clarinet player, an E-flat alto sax or an F horn: under Written for, the notes and the key signature move to that instrument's written pitch while playback stays at concert pitch. To transpose a score you already have as a file, use transpose sheet music; to get just the MIDI of a sung line, use voice to MIDI.

Write a Part

Play it back, fix it, export it

Press play and a cursor walks through the score, so you hear where the transcription differs from the recording. Click a note to hear it, move it a semitone (Shift with the arrow keys moves an octave) or delete it, and undo any change. Then print or save a PDF from your browser's print dialog, export PNG or SVG, or take MusicXML into a notation app and MIDI into your DAW.

Export Your Score

Audio to Sheet Music Example: Four Real Recordings

Real engine output, not a mock-up: the notes this site's engine heard in the four sample recordings, engraved by the converter's own notation code. Switch recordings and grids and listen while the cursor follows the bar.

bach-prelude-c.mp3

Kimiko Ishizaka, piano · public domain

44 notesKey: C major♩ = 1114 bars · 4/4

What you are looking at

Kimiko Ishizaka playing the Bach Prelude in C, a hummed tune, a guitar solo and a walking bass line, each credited with its source and licence. Each one opens with its own preset: a grand staff for the piano, one line for the voice, the treble staff for guitar and the bass clef for bass. Compare the 1/16 grid with the 1/8 grid to see how much quantizing decides, and play the original recording to hear what the song to sheet music engine heard.

How Accurate Is Audio to Sheet Music? An Honest Answer

Accurate enough to save hours on clear recordings of one instrument, and rough on full band mixes. Automatic music transcription is still an open research problem: every tool, ours included, misses notes in dense chords, adds a few ghost notes from overtones and reverb, and has to guess the rhythm a player meant. Treat the result as a careful first draft that you check by ear, not a published edition, and you will get the most from it. We do not quote an accuracy percentage, because it changes from one recording to the next.

  • A full song mix with drums, bass and vocals gives a crowded, rough score.
  • Drums are not written: the converter writes pitched notes only.
  • Dynamics, slurs, pedal marks and lyrics are not added to the score.
  • Rubato and free tempo need a hand: set the meter and grid, then fix the bars.

What to Expect from MP3 to Sheet Music by Recording Type

The recording matters more than the converter. Here is what this MP3 to sheet music converter gives you for each kind of source, and the best next step.

What to Expect from MP3 to Sheet Music by Recording Type
Solo piano, close and cleanA grand staff with most notes right; dense chords lose a note or twoUse the Piano preset, check the hand split, then print
One voice, whistle or solo instrumentA clean single line; slides and vibrato can add short extra notesUse Voice or Solo melody and the coarser grid
Guitar picking or a bass lineSingle notes come through well; strummed chords are roughUse Guitar or Bass; for tab, try the guitar tab generator
A full band or a song mixA crowded score with parts mixed togetherIsolate the part first, or transcribe just the melody you sing back
Phone recording in a noisy roomExtra short notes from noise and echoRecord closer, then lower the sensitivity, hide unsure notes and delete strays
Drums and percussionNot written: drum notation is not supportedTranscribe the pitched parts instead

Who Uses a Song to Sheet Music Converter

Anyone who can hear the music but has no page to read it from, whether they need to convert a song to sheet music once or every week.

Learners working out a piece

Find the notes of a song you love: turn the MP3 into sheet music, print it and practise from the page. For a piano arrangement on a grand staff, use the song to piano setup.

Songwriters and singers

Sing the idea into your phone, convert the song into sheet music and hand the band a lead line instead of a voice memo. Need it in another key? Change it before you print.

Music teachers

Play an exercise once and print it, make ear-training answers, or write one recorded melody for B-flat, E-flat and F players. Quick transcription, music for a school band and handouts for a lesson all start the same way: convert music to sheet music once, then print.

Players in a band

Convert music into sheet music straight from a rehearsal recording: keep a solo or a bass line as notation, as MIDI for your DAW, or as tabs with the bass tab generator.

Audio to Sheet Music Questions, Answered

Straight answers, including what the converter cannot do and what the law around sheet music looks like.

How do I convert audio to sheet music?

Drop the recording on the converter at the top of this page, or record one, and choose the instrument. Basic Pitch transcribes it in your browser; check the key, time signature and grid, play it back and fix stray notes, then print, save a PDF or export MusicXML and MIDI. It is free and needs no account.

Can I convert MP3 to sheet music free?

Yes. You can convert MP3 to sheet music online, free, with no sign-up, no watermark and no short preview clip in place of the transcription, and every export is the full score. WAV and other common audio files work the same way, so you can transcribe music online without installing anything.

Is there AI that can transcribe music?

Yes. Automatic music transcription models such as Spotify's Basic Pitch, which this converter uses, listen to a recording and output the notes they hear. Can AI transcribe music perfectly? Not yet: an AI sheet music transcriber does well on one clear instrument and struggles with dense chords and full band mixes, so a musician still checks the result.

What is the best AI to transcribe a song?

It depends on the song. For a solo piano, voice or single instrument, a free tool like this one gives a usable first draft. For a full band mix with many instruments, the best AI music transcription comes from paid services with multi-instrument models (Songscription, Klangio), and a human music transcriptionist will usually get closer still. The comparison above lists what each tool offers as of November 2026.

What is the best free music transcription software?

For a browser tool with nothing to install, ToMIDI is a free sheet music generator with full-length scores and every export, and your audio stays on your device. MuseScore Studio is the best free notation editor to finish the job: open our MusicXML in it. If you want an AI music transcription free trial of a paid service, Songscription, Klangio and AnthemScore all offer short free clips.

How accurate is the transcription?

It depends on the recording far more than on the settings. One clearly recorded instrument comes out close, with a few notes to fix; a full mix of a song comes out rough. We do not give a percentage because no single number would be honest across recordings. Play the original against the score, hide the notes the model was unsure about or snap stray notes to the key, correct what you hear, or export MIDI and clean it up in the MIDI editor.

Can it transcribe a full song with a band?

It will write what it hears, but a full mix gives a crowded score with the vocal, the bass and the chords mixed together, and drums are not written at all. For a usable page, isolate the part you want first, or sing or play the melody yourself and transcribe that. To get MIDI of the whole mix for a DAW, try MP3 to MIDI.

Is it illegal to print sheet music without buying it?

It depends on the piece and the edition. This is general information, not legal advice. Music whose copyright has expired is in the public domain in many countries, and libraries such as IMSLP and the Mutopia Project share those scores for free. Sheet music for a song still under copyright is normally sold by its publisher, so buy it from a licensed shop or borrow it from a library. Terms differ by country, and a modern edition or arrangement of an old piece can carry its own copyright.

Can I legally download free sheet music, or make my own?

Downloading is generally fine when the score is in the public domain where you live or the person who made it shares it under an open licence, as on IMSLP and Mutopia. Writing down a song from a recording for your own practice is a common private use; sharing, selling or performing that transcription in public can need permission from the copyright owner. Check the rules in your country before you publish anything.

Where can I find free piano sheet music legally?

For classical piano, IMSLP (the Petrucci Music Library) and the Mutopia Project hold large collections of public domain scores. Public libraries lend printed music as well. For a song with no free score, make your own from a recording you are allowed to use: drop it on this converter with the Piano preset and keep the result for your own practice.

Can I record myself instead of uploading a file?

Yes. Choose Record, allow the microphone, and sing, whistle or play; the take is transcribed like any file. There is no transcribe music app to install, because it works in your phone's browser. A quiet room and a phone held close to the instrument give the cleanest score.

Can I find the notes of a song by humming it?

Yes. Hum or sing the tune with the Voice preset and the converter writes the melody as one line on a staff, so it works as a song to notes converter. Hum on a clear syllable like "da" and keep a steady tempo for the cleanest line. To name a single note you sing, use the pitch detector.

Can I open the score in MuseScore, Sibelius, Finale or Dorico?

Yes. Export MusicXML and open it in any of them to add dynamics, lyrics and layout. MusicXML keeps the key, meter, clefs and quantized rhythm you chose, which is a better start than importing raw MIDI. You can also hear it again later with MusicXML to MIDI.

What is a music transcriber, and what is transcribing music?

Transcribing music means listening to a performance and writing it down as notation. A music transcriber is the person, or the program, who does that; a music transcriptionist usually means a professional you hire, and music transcription services sell that work for a fee. In short, the music transcription meaning is "from sound to sheet music", which is what this converter automates for a first draft.

Which audio to sheet music AI does ToMIDI use, and is my audio uploaded?

Basic Pitch, Spotify's open-source note detection model, running inside your browser tab with the rest of the converter: the transcription, the engraving and the exports. Your recording is not sent to a server, and closing the tab clears it. Because it runs on your device, a long file takes longer on an older phone than on a laptop.

Can I turn sheet music back into audio or MIDI?

Yes, with our other tools: export MIDI here and play it in the MIDI player, use MusicXML to MIDI for notation files, and PDF to MIDI or the sheet music scanner for printed or scanned scores.
