Choir Singers Pilot – An online platform for choir singers practice
summary
A web app generates synchronized practice tracks from scores using Voctro singing synthesis and mixes parts in-browser with Web Audio API while applying in-browser latency compensation. User recordings undergo pitch extraction and alignment, then an intonation score is computed as the median difference per score note and displayed as colored score feedback. The project synthesizes 84 pieces, worked with 13 choirs, produced virtual-choir mixes and workshops, and is deployed as the Cantamus rehearsal product with a public catalog of CPDL-derived scores.
