BandConvert

BandConvert is a powerful web application that transcribes polyphonic audio files and YouTube videos into detailed multi-instrument sheet music, MIDI, and MusicXML. Designed for composers, arrangers, teachers, and ensemble musicians, BandConvert uses a custom AI engine specialized in recognizing layered instruments (piano, guitar, bass, drums, wind, strings...). It detects pitch, rhythm, tempo, time signature, clefs, and articulations, and separates instrument tracks with high accuracy. No software to install — just upload your audio or paste a video link and get professional-quality, editable scores in seconds.
