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 4):
The method of  claim 1  further comprising loading the selected set of filter coefficients to an adaptive filter, adapting the adaptive filter coefficients, and copying the adaptive filter coefficients to an active audio filter that performs the filtering.
