An apparatus and method for remotely and automatically adjusting the volume of
a remotely controlled audio device. In one embodiment, the apparatus comprises
a sensor circuit for continuously detecting audio signals generated by the audio
device, a difference circuit for determining the difference between the amplitude
of the detected audio signals and a reference audio signal amplitude and for outputting
a signal that represents this difference, a difference signal transfer circuit
having an input for receiving the difference signal and an output wherein the difference
signal is coupled to the output when the sensor circuit outputs a signal that indicates
an audio signal has been detected, and a control circuit for generating a control
signal that effects attenuation, augmentation or maintenance of the amplitude of
the audio signals generated by the audio device in accordance with the difference
signal when the sensor circuit detects an audio signal.
