Patent ID: 8705757

Claim:
A signal processor comprising: a feedback delay network (“FDN”) having an input to receive an audio signal and an output to produce an exponentially-decaying reverberation tail signal based on the audio signal; a delay module having an input coupled to the output of the FDN to receive the exponentially-decaying reverberation tail signal and produce therefrom a plurality of variously-delayed versions of the exponentially-decaying reverberation tail signal, the plurality of variously-delayed versions of the exponentially-decaying reverberation tail signal hereinafter referred to as a plurality of reverberation tail echo signals; and a panning module having a first input coupled to receive the audio signal, a second input coupled to the FDN to receive the exponentially-decaying reverberation tail signal, and a plurality of third inputs coupled to the delay module to receive the plurality of the reverberation tail echo signals, the panning module configured to produce therefrom a plurality of signal channels, the plurality of the signal channels being subsequently combined into a single encoded signal for reproduction on a multi-channel audio system.
