Abstract
A method of performing audio synthesis has a first audio event input to an audio algorithm along with associated parameters. A synthesis algorithm accesses a soundbank to generate audio output. The soundbank has two or more levels for a first desired sound. A first level is associated with a first sample of a relatively chaotic waveform, and a second level is associated with a second sample of a relatively stable waveform. Parameter data is associated with one or more of the levels. The first sample and the second sample begin to sound at the same point in time in response to the first audio event. The audio output is based in part on the parameter data, and the second sample is continuously looped until a second audio event is detected.
