Abstract: An audio processor (202) receives a non-priority audio signal (302) and a priority audio signal (304). The priority audio signal occupies a frequency band (408). The audio processor filters (320) the non-priority audio signal by suppressing frequency content in the same frequency region occupied by the priority signal, creating a filtered non-priority signal (412). The filtered non-priority signal and the priority signal are combined (328) and played over an audio transducer (110).

Abstract: A method and a system for implementing echo cancellation. The method (300, 400) can include, on a first communication device (200), generating an acoustic signal (130) corresponding to an audio signal (110) received from a second communication device. Responsive to receiving a portion of the acoustic signal and detecting it is clipped, filter coefficient adaptation in an echo cancellation system (205) can be neutralized. For example, filter coefficients can be maintained at previous values, a control signal (230) that indicates zero error can be provided to an adaptive algorithm (235) that generates filter coefficients (225), a control signal can be provided that indicates to the adaptive algorithm to halt automatic updating of the filter coefficients that are generated, or a control signal can be provided that indicates to an adaptive filter (245) to halt automatic updating of the filter coefficients that are processed.
