Granular synthesis has been used for a number of years as a sound synthesis technique. Efficient methods of producing and combining these grains are currently especially interesting, because the recent development of special-purpose digital signal processing (DSP) microprocessors has made real-time granular synthesispossible at a reasonable hardware cost. This paper discusses the computational aspects of granular synthesis. Methods of extracting grains from natural signals and recombining them with phase alignment are described. Fast methods for digital generation of synthetic signals with linear frequency modulation (FM) are also presented.
