  • receiving at the audio processor a priority audio signal occupying at least one frequency band;

    receiving at the audio processor at least one non-priority audio signal having a bandwidth greater than the at least one frequency band;

    stop-band filtering the at least one non-priority audio signal to provide at least one filtered non-priority audio signal, wherein the at least one frequency band is suppressed in the non-priority audio signal by the stop-band filtering and frequencies outside the at least one frequency band are not suppressed by the stop-band filtering; and

    combining the priority audio signal and the at least one filtered non-priority audio signal to provide an output signal.
