Omnizart vs Songscription

Omnizart is a free Python library for transcribing polyphonic music into pitched instruments, vocal melody, chords, drum events, and beats. Pre-trained checkpoints allow transcription without first training a model. The project also documents dataset downloads, feature preprocessing, model training, transcription, and sonification, with MIDI, CSV, and text output formats. It lists separate applications for music, drums, vocals, vocal contours, chords, and beats, along with chord detection, MIDI export, and stem separation. Installation options include pip, Docker, and Conda, and a command-line interface is provided. Documentation links to a Colab notebook and a Replicate web demo. Omnizart supports Linux, Windows, macOS, and self-hosted setups, but is incompatible with ARM-based macOS because of underlying dependencies. The package requires Python 3.8 or later and below 3.15. Drum checkpoints can be used for transcription, though the drum model has an unresolved issue that prevents loss convergence when training from scratch. It is MIT-licensed and offers GitHub Issues for installation, compatibility, and usage problems.

Songscription is a web-based music transcription platform that converts audio recordings and video links into sheet music, MIDI, guitar tabs, and an interactive piano roll. It accepts MP3, WAV, FLAC, AAC, M4A, MP4, MOV, or WebM files, YouTube, Instagram, and TikTok links, browser recordings, and MIDI or MusicXML imports. It transcribes piano, guitar, bass, double bass, violin, flute, trumpet, saxophone, drums, and vocals, one instrument at a time. Transcriptions can be edited note by note, including pitches, timing, note deletion, and hand assignment. Piano cover mode arranges a song for piano, while chord detection attempts to identify chords in a performance. Exports include PDF, MIDI, MusicXML, and Guitar Pro. The free plan allows unlimited 30-second transcriptions. Plus costs $99.90 a year and Pro costs $299.90 a year, each billed annually before tax; both allow transcriptions up to 15 minutes. Songscription works in mobile browsers as well as desktop browsers.
