Abstract:
1. A communication device, comprising: communication elements configured to receive audio signals from a far end communication device during a call; a memory device storing a plurality of different sets of echo cancellation training parameters for an adaptive filter that performs echo subtraction for an echo canceller, each set of echo cancellation training parameters corresponding to a different audio mode for the communication device; and a processor operably coupled with the communication elements and the memory device, the processor configured to execute the echo canceller by switching between loading a first set of echo cancellation training parameters responsive to a first audio mode being selected, and a second set of echo cancellation training parameters responsive to a second audio mode being selected, wherein the echo canceller is configured to: store the different values as updated echo cancellation training parameters for the corresponding set of echo cancellation training parameters of the selected audio mode responsive to exiting the selected audio mode.
