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 16):
A multi-channel audio system comprising:\n a sound stage processor having one or more outputs configured to provide processed signals; a plurality of content channels, each of the plurality of content channels configured to convey a selected audio content signal from a source to the sound stage processor; and a plurality of echo canceling filters, each of the echo canceling filters associated with one of the plurality of content channels, and each of the echo canceling filters configured to filter the associated selected audio content signal into an estimated echo signal using a set of filter coefficients selected from among a plurality of sets of filter coefficients, the selected set of filter coefficients representing an estimated echo response of the audio system to the selected audio content signal, including an array processing configuration of a plurality of microphone signals.
