Ball Jam is a volumetric audio composition created by Zack Settel, combining motion tracking, realtime audio processing, and physical modelling in a virtual environment.
Commissioned and performed by the Quasar Saxophone Quartet (quasar4.com), the piece allows players to capture samples from their instruments and apply effects based on their location on stage.
