Free Audio to Sheet Music Converter

Yes. It runs in your browser, uses no credits and needs no account for piano, vocal, guitar and bass from a single recording.

No. The models run on your device. Only static model and sound files are downloaded, and only the score is saved if you choose to share it. If you use the optional AI assistant, your instruction and the score data are sent to WaveSpeed, never the audio. WaveSpeed keeps what it receives for up to 7 days and does not use it to train models.

Solo piano works best. Songs with many instruments give more mistakes, so check the score and fix notes in the editor.

Multi-instrument and piano arrangement modes first split the song into six tracks with the free Local 6 tracks, which needs an account.

A PDF, a MIDI file, MusicXML for MuseScore and other notation software, and a Guitar Pro 7 file. Guitar and bass include tablature, piano can include finger numbers, and drums are written on a percussion staff.

Only if you have permission. You confirm this before each run, and shared scores must not infringe copyright.

Yes. For piano you can choose Original, Intermediate, Easy or Beginner. The melody stays in the right hand, the left hand becomes chords, root and fifth, or single roots, the rhythm is simplified and the piece can move to an easy key. Each level shows a difficulty from 1 to 10 and the main reasons.

It is free for signed-in accounts with a verified e-mail, within a daily limit. It sends only your instruction and the score data (notes, bars, key and tempo) to WaveSpeed, never the audio. It can only suggest edits from a fixed list, you see a preview first, and nothing changes until you apply it. WaveSpeed keeps what it receives for up to 7 days and does not use it to train models.

Drums are a beta. A simple detector finds kick, snare and hi-hat in the drum track of a song and writes them on a percussion staff. Toms and cymbals are not detected, so check every bar and fix it in the drum lanes.

Songs with a singer, yes: the vocal melody becomes the right hand, the chords and the bass line become the left hand, in four styles (block, broken, pop, waltz) and four levels, and you can show piano plus vocal on three staves. Songs without a singer are not supported in this mode; use Piano mode, or Multi-instrument mode for a band. The melody is approximate, so check the right hand and fix it in the editor.

In our tests on four generated songs, about nine chords in ten matched beat by beat once the bass line was used to check them (about eight in ten without). Real recordings are harder: dense mixes, extra notes and inversions cause more mistakes, so use the chord symbols as a guide, hide them if they distract, and fix notes in the editor.

Yes. Choose an MP4, MOV or WebM video and only its sound is read, on your device: the picture is never loaded or uploaded. A MIDI or MusicXML file (.mid, .musicxml, .mxl) opens at once as a score, with the tempo, meter and key from the file. You can edit it, add fingering, make it easier, share it and export it like a transcription.

In the piano roll, turn on Practice mode. Each bar shows its finger number and is blue for the right hand or orange for the left. Slow the music down to 25 to 100 percent and mute either hand to play along with the other. Wait mode, which stops for you to play the right note, needs a MIDI keyboard and is not offered yet.

You say once how wide a stretch each hand can make, how many notes a hand can play at once, the fastest notes you can play and how many sharps or flats you read. Only the bars that ask for more than that are made simpler; every other bar keeps its notes. A strip shows how hard each bar is and marks the bars that changed. Your profile stays in this browser and needs no account.

Yes, by typing or pasting them. They are spread over the notes of the vocal line, one character per note for Chinese, Japanese and Korean and one syllable per note for other languages, and you can change, move or hold each syllable. They appear in the PDF, in MusicXML and in Guitar Pro. Lyrics are not recognised from the audio, because singing is too hard for a small model that runs in your browser.

Yes. The free sheet music library has more than seventy public-domain pieces and traditional songs, more than thirty of them complete (taken from the Mutopia Project and checked against its MIDI files note for note), with a score, a piano roll and practice mode, transposing, the easier levels and a free PDF and MIDI download. The library pages are in English and Chinese.

Yes. In practice mode, switch on “Wait for me”: playback stops at each note or chord until you press the right keys on a MIDI keyboard or on the on-screen keyboard, one hand at a time if you like. It works in Chrome and Edge on a computer or an Android phone; Safari has no Web MIDI, so there you use the on-screen keyboard. The keys you press stay in your browser. Wait mode with a microphone for an acoustic piano is not available.

Yes. Choose or drop up to 10 files (audio, video, MIDI or MusicXML). They are processed one after another in your browser with the same mode and options, so a long queue takes as long as the files would one by one; keep the tab open. A file that fails does not stop the others, you can cancel the queue, open each result in the usual view and download everything as one ZIP with the formats you pick (PDF, MIDI, MusicXML, Guitar Pro). The limits per file are the same as for a single file. There is no public API: the transcription runs in your browser, not on our servers.
