Approximate audio processing in an audio graph for interactive music systems

Abstract : Interactive music systems are highly dynamic systems that combine audio processing and control in real-time, and they often have to work on soft real-time platforms, where no stringent real-time guarantees can be upheld. We present here an overhead-aware online degradation algorithm that find a tradeoff between quality and lateness for the processing nodes of a dynamic audio graph. We show that we can scale to thousands of nodes.
