A processor-based system may control the volume level of information played by said processor-based system. The system may allow the user to set one or more preset audio volume levels and the system automatically implements those levels. In one embodiment of the present invention, a remote control unit may have a microphone which records audio volume levels produced by the system and provides information which allows the system to determine whether the audio volume is within the desired ranges. If not, the audio levels may be adjusted. As a result, the audio levels may be monitored at a location proximate to the user's position with respect to the processor-based system.
