Digital manipulation of audio samples

摘要

The sound of a plurality of a selected instrument is derived from a single digitized audio sample of the selected instrument by storing the digitized audio sample of the single selected instrument in a memory and manipulating copies of the digitized audio sample 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 which is converted to an analog signal which is sent to a speaker to produce the sound of the plurality of the selected instrument. <MATH>
