Patent ID: 8859876

Claim:
A multi-channel signal processing system comprising: a signal interface for receiving a plurality of distinct incoming audio electrical signals, each incoming audio electrical signal produced by an associated transducer in response to vibrations of an associated vibrating element from within a plurality of vibrating elements, wherein a first associated transducer produces a first of the plurality of distinct incoming audio electrical signals produced in response to the vibrations of a first of the plurality of vibrating elements, wherein a second associated transducer produces a second of the plurality of distinct incoming audio electrical signals produced in response to the vibrations of a second of the plurality of vibrating elements, and wherein a third associated transducer produces a third of the plurality of distinct incoming audio electrical signals produced in response to the vibrations of a third of the plurality of vibrating elements; a plurality of signal processors, each signal processor comprising a respective pitch shifter, wherein each processor of said plurality of signal processors receives a respective one of said plurality of incoming audio electrical signals, wherein each processor of said plurality of signal processors is configured to: process a respective received incoming audio electrical signal to produce a respective audio output signal including, pitch-shifting said received incoming audio electrical signal by utilizing the respective pitch shifter; an output signal interface for providing said audio output signal for each of said plurality of signal processors, wherein a first signal processor of the plurality of signal processors is configured to pitch shift a first received incoming audio signal independently from a second received incoming audio signal, which is pitch shifted by a second signal processor of the plurality of signal processors, and wherein the first and second pitch shifters are configured to be individually controlled in real time by a user-operated controller, the user-operated controller that is associated with the source of the plurality of distinct audio electrical signals.
