Abstract:
Audio systems and methods are provided to reduce echo content in an audio signal. The systems and methods receive an audio signal and sound stage rendering parameter(s), and select a set of filter coefficients to filter the audio signal to provide an estimated echo signal. The estimated echo signal is subtracted from a microphone signal to provide an output signal with reduced echo content. The set of filter coefficients are selected based upon the sound stage rendering parameter(s) from among a plurality of stored sets of filter coefficients.

Claim (Index 8):
The method of  claim 1  further comprising changing the audio system configuration by identifying a second audio system configuration, selecting a second set of filter coefficients based upon the second audio system configuration, the second selected set of filter coefficients representing an estimated echo response of the audio system including a second array processing configuration of the plurality of microphone signals, array processing the plurality of microphone signals in accord with the second array processing configuration, and filtering the audio program content signal using the second selected set of filter coefficients to generate the estimated echo signal.
