Abstract
A technique for producing a sound of a plurality of a selected instrument from a digitized audio sample of the selected instrument. The digitized audio sample of the single selected instrument is stored in a memory. Next, copies of the digitized audio sample are micromanipulated in parallel in a plurality of digital processors corresponding in number to the plurality of the selected instrument. Each of the digital processors processes the digital audio sample in a slightly different time variant manner to produce the effect of a plurality of instruments. The processed digital audio samples are summed into a single digital sample. The summed digital audio sample is converted to an analog signal which is sent to a speaker to produce the sound of the plurality of the selected instrument.
