Multirate Extensions for Model-Based Synthesis of Plucked String Instruments
Vesa Välimäki, Tero Tolonen · 1997
We describe new developments for model-based sound synthesis of plucked string instruments. The synthesis model is based on the extended Karplus–Strong algorithm. A new implementation approach where part of the excitation signal is modeled with interpolated low-frequency resonators and the decay part of the tones using a multirate string model is introduced. The resonators allow for a full parametri-zation of the lowest body modes. The computational burden and memory requirements of plucked string synthesis are decreased using the proposed techniques without degrading the sound quality. 1
