MuScriptor vs Piano2Notes

MuScriptor turns audio recordings into MIDI and sheet music, with downloadable MIDI files, sheet-music PDFs, and guitar-tab PDFs from its hosted service. The web demo accepts MP3, WAV, FLAC, OGG, M4A, AIFF, and Opus files. It can transcribe voice, piano, guitars, bass, strings, brass, woodwinds, drums, and other instruments, and users can specify which instruments they expect to improve transcription accuracy. Guitar and bass parts can include tablature alongside standard notation, but the system does not produce chord symbols. MusicXML output can be edited in MuseScore, Sibelius, or Guitar Pro. Users can self-host the web interface, and transcription is also available through a CLI and Python API. Local use requires Hugging Face authentication and acceptance of the model's CC BY-NC 4.0 license. Hosted audio is processed on the server and not retained afterwards; local use keeps audio on the user's machine. The service says it performs better on acoustic and guitar music than electronic music, and that results are not perfect. The hosted demo is free; the code is MIT-licensed, while model weights carry the non-commercial license.

Piano2Notes uses AI to turn piano audio into sheet music, MIDI, or MusicXML. Users can record in the app, upload an audio file, or supply a YouTube link. It is designed to transcribe melodies and chords, including piano parts in recordings with other instruments. A built-in editor lets users adjust notes, timing, and layout, while Piano Roll mode provides a view for playing along. Exports include PDF sheet music, quantized or unquantized MIDI, and MusicXML, which the maker says can be used with notation software and DAWs. The free demo covers only the first 20 seconds of each recording, file, or video. Piano2Notes Pro costs $14.99 a month and includes 50 full transcriptions monthly, each up to 15 minutes. The maker says results work best with well-recorded, piano-focused music and offers an editor for correcting small errors. Piano2Notes is available on Android, iOS, and web, and work syncs between desktop and mobile platforms.
