2012A singing-practice app I first built in 2012-13, before browsers could do the audio work it needed, and rebuilt in 2026 on AI models, offline and real-time signal processing, and algorithms of my own: upload a recording and it becomes a track you can sing, with the vocal removed, key and tempo moving independently, and phrase-by-phrase call-and-response practice.
