Questions, answered plainly

Yes. Upload a recording or video of solo piano to Hear It, Score It, or paste a link, and a few minutes later you get the sheet music: a score to read on screen, a PDF to print, a MusicXML file to edit in MuseScore, and a MIDI file of the performance.

For solo piano, yes, and it is good enough to learn from. A neural network trained on piano recordings writes down each note it hears, then our software lines the notes up on the beat, splits them between the hands and engraves the score. It is not perfect, which is why notes it is unsure of are printed in grey.

One piano, recorded clearly, with a reasonably steady beat. A phone placed near the piano in a quiet room is enough. A grand, an upright or a digital piano will do.

Not well. It is built for solo piano. Voices, drums and other instruments get written down as if they were piano notes. If you can, find or make a recording of the piano part alone.

Audio: MP3, WAV, M4A, AAC, FLAC and OGG, including voice memos from a phone. Video: MP4, MOV and WebM; we take the sound out ourselves. Files can be up to 200 MB and 20 minutes long.

You can paste a link to a video, and you confirm you have the right to use that recording. Some video sites block downloads, so if a link cannot be fetched we tell you and you can upload the file instead. Your minutes are not charged for a link that fails.

A score you can read on screen, a PDF to print, a MusicXML file that opens in MuseScore, Sibelius, Finale, Dorico and most notation apps, and a MIDI file of the exact performance.

Yes. Download the MusicXML file and open it in MuseScore, which is free. That is the easiest way to fix any notes the machine got wrong.

Yes. Pick any of the twelve keys and the whole score moves, with the right key signature, and the PDF and MusicXML follow. Key changes are free and unlimited and never use minutes.

The shorter way. Moving from C to D goes up a step, and moving from C to B goes down a half step, so the music stays near where it was written.

Clean solo piano recordings come out well, close enough to learn from with a little checking. It struggles with very free timing, fast ornaments, crossed hands and heavy pedal. We do not publish a percentage, because a single number hides where the mistakes are. Instead, notes the machine is unsure of are printed in grey, so you know where to listen twice.

Notes the machine heard but is not confident about. Most are right. They are the first place to check against the recording.

Pieces in three-four time or that start with a pickup note can be counted from the wrong beat. Open the MusicXML in MuseScore to shift the bar lines; the notes themselves are usually fine.

Every new account gets 20 free minutes of audio, enough for several whole songs. No card is needed. After that you buy minutes in packs.

Packs are 60 minutes for $9, 200 minutes for $24, 600 minutes for $59. A job uses the length of the audio, counted to the second, so a four-minute song uses four minutes.

No. You buy a pack once. Nothing renews and minutes never expire.

If a job fails, its minutes come back by themselves. If you are not happy with a pack, write to us within 14 days for a full refund.

No. Your recordings are used only to make your score. Uploads are deleted 30 days after the job unless you keep the score in your library.

Writing a song out for your own practice is a normal private use. Sharing, selling or publicly performing the arrangement generally needs permission from the publisher, and churches often rely on a licence such as CCLI's for copying and arranging. Music in the public domain, such as Bach, Mozart or Chopin, is free for anyone. This is general information, not legal advice.
