Abstract: An audio integrator monitors the outputs of a plurality of audio sources, and a controller prioritizes the audio sources. An active audio detection circuit determines when one or more of the audio sources become active. When the two or more audio sources are active simultaneously, the controller directs the highest priority audio source to one or more speakers. If a lower priority audio signal is currently playing, newly active voice communication audio, such as communications or directional information, is delayed to preserve the beginning of the message during an audio switch-over. A currently-playing, lower-priority audio signal may be decreased in volume, and a tone unique to the new audio source sounded, prior to the switching the audio to the higher-priority source. During audio input (e.g., while actuating a push-to-talk button on a microphone), all active audio sources are quieted.
