Violin2Notes
Karlsruhe, Germany
What it is
Violin2Notes uses AI to turn recordings of violin, viola, cello and double bass into sheet music, MIDI and MusicXML. You can upload an audio file, paste a YouTube link or record in the app; supported upload formats include MP3, WAV, MP4, MIDI and FLAC. The built-in editor lets you adjust notes, timing and layout before exporting PDF sheet music, quantized or unquantized MIDI, or MusicXML. Piano Roll mode offers an interactive way to view and play along with a transcription. The tool can transcribe string parts even when other instruments are present. Free demos can be repeated and cover the first 20 seconds of audio, a video or an in-app recording, with a PDF preview. Pro allows 50 full transcriptions per month, each up to 15 minutes. It costs $14.99 a month or $6.24 a year, shown as an equivalent monthly cost with annual billing. The service is available on web, iOS and Android, and the maker says transcriptions sync between them. The maker says results work best with clear recordings focused on strings, and can be corrected in the editor.
