ScoreStarling is a music conversion and notation workspace for musicians, arrangers and music learners. Move musical content between sound, pictures, documents and score files. Start from an audio or video recording, an image or PDF of sheet music, MIDI, MusicXML, ABC, numbered notation, a lead sheet, or music written in the chat. Turn it into an editable, playable score, then convert it to PDF, SVG/PNG images, MusicXML, MIDI, MP3/WAV audio, ABC, MEI, individual parts or numbered notation. Read and hear the result, compare a source recording with score playback, review uncertain passages, preview edits, apply accepted changes and undo them. Recordings of one instrument or voice, or of solo piano, are free; a band uses credits, and its price is shown before it starts. Sign in with a ScoreStarling account. Uploads are limited to 50 MiB, or 120 MiB for WAV, AIFF or FLAC. Audio and video transcription cover the account’s supported excerpt, up to five minutes; the length limit, and for a band the price, are shown before starting. Automatic transcription and sheet-music reading can contain pitch, rhythm or notation errors, so listening and human review are needed.
