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 ).
