Dynamic Convolution Modeling, a Hybrid Synthesis Strategy


This article outlines a hybrid approach to the synthesis of percussion sounds. The synthesis method described here combines techniques and concepts from physical modeling and convolution to produce audio synthesis of percussive instruments. This synthesis method not only achieves a high degree of realism in comparison with audio samples but also retains some of the flexibility associated with waveguide physical models. When the results are analyzed, the method exhibits some interesting detailed spectral features that have some aspects in common with the behavior of acoustic percussion instruments. In addition to outlining the synthesis process, the article discusses some of the more creative possibilities inherent in this approach, e.g., the use and free combination of excitation and resonance sources from beyond the realms of the purely percussive examples given.
