Explorations in Convolutional Synthesis

In this work we further explore a previously proposed tech-nique, used in the context of physical modeling synthesis, whereby a waveguide structure is replaced by a low-latency convolution operation with an impulse response. By do-ing so, there is no longer the constraint that successive ar-rivals be uniformly spaced, nor need they decay exponen-tially as they must in a waveguide structure. The struc-ture of an impulse response corresponding to an acoustic tube is discussed, with possible synthesis parameters identi-fied. Suggestions are made for departing from a physically-constrained structure, looking in particular at impulse re-sponses that are mathematically-based and/or that correspond to hybrid or multi-phonic instruments by interleaving two or more impulse responses. The result is an exploration of vir-tual musical instruments that are either based on physical in-struments, completely imagined, or somewhere in between.
