EchoVQ: AI-Powered Vocal Training Platform EchoVQ is an AI-powered vocal training platform built for music educators and schools. Upload any song and EchoVQ separates it into individual stems (vocals, drums, bass, instruments), detects chords and key signature, generates lead sheets, and creates note-by-note pitch visualisations. Teachers manage students, assign exercises, build practice plans, and track progress. Students record themselves singing over any stem mix, then share or export their performances. AI coaching provides personalised feedback on pitch, timing, and technique. Currently used by 20+ schools across Australia with site licensing, teacher dashboards, and classroom analytics.
