posted on 2023-07-04, 14:11 authored by Chris KieferChris KieferThere are many metrics available for observing the dynamical complexity of a signal, with multiple applications incomputer music. Previous work demonstrated that the Effort To Compress metric could be used to modulate the behaviour of a feedback instrument, however the algorithm is challenging to run in realtime. This research explores the many metrics available, and evaluates a selection of them in their suitability for realtime signal processing in musical instruments. A new metric is proposed and evaluated: Random Projection Complexity (RPC). The results show that RPC has comparable performance to other complexity metrics, and is suited to realtime applications. The results also demonstrate viability of further complexity metrics for interactive computer music systems.
