ASR Studio is an audio toolkit designed to complement the Audio Shoulder Rest (ASR) — a smart, audio-enabled shoulder rest for string instruments, created by Matter Squared. Used by professionals, amateurs, educators and students alike, ASR Studio helps transform practice sessions into interactive learning experiences. Whether you're tuning up, syncing bow strokes to the metronome, or practicing intonation, the app empowers string players to listen more deeply and practice with purpose. While designed for integration with the ASR hardware, the app also works independently.
