Virtual strings filter design revisited
Julius O. Smith · The Journal of the Acoustical Society of America · 2021
Digital filters have been used for decades to simulate losses and dispersion in real-time vibrating-string models for musical sound synthesis. String-loop filters in digital-waveguide models have generally been very low-order due to CPU limitations on typical available devices. In recent years, CPU speeds have increased so dramatically that very realistic string models can easily run in real time. This presentation revisits filter design for real-time musical string modeling.
