Optimization of audio graphs by resampling
Interactive music systems are dynamic real-time systems which combine control and signal processing based on an audio graph. They are often used on platforms where there are no reliable and precise real-time guarantees. Here, we present a method of optimizing audio graphs and finding a compromise between audio quality and gain in execution time by downsampling parts of the graph. We present models of quality and execution time and we evaluate the models and our optimization algorithm experimentally.
