About Instrufilt
Instrufilt is an open-source, browser-based audio isolation tool released under Betania.io. It isolates lead vocals, mutes backing instruments on browser audio, and displays synchronized chord lead sheets. Designed for real-time play-along practice across web platforms like YouTube, Spotify Web, and SoundCloud, it offers multiple isolation modes including vocal with rhythm, vocal only, and lead line. All processing occurs locally in real time through a WebAssembly AudioWorklet without uploading audio to remote servers.
