Melody Scanner vs MuScriptor

Melody Scanner automatically turns songs into sheet music. Users can record an instrument, import MIDI, MusicXML or MP3 files, or generate scores from YouTube videos. Scores can be edited in classical notation, piano roll or guitar tabs views, with PDF export available. Listed modes include piano, guitar, flute, violin, saxophone, bass, singing and chords. The maker says piano mode supports polyphony, velocity and hand separation, with accuracy up to 86%; smart editing can help transpose scores and label chords. The app runs in a browser without installation and is also listed for iOS and Android. The free plan allows recordings up to one minute and sheets limited to 40 bars or about two minutes. Monthly access is $9.99 a month; the yearly subscription is $49.99 a year, billed annually. Paid plans list recording up to five minutes, full sheets and MIDI/MusicXML export. The product currently supports solo instruments, not bands or orchestras.

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.
