Claim 0:
1. An audio system that is configured to more evenly distribute sound across an environment in which the audio system is located, comprising:
a loudspeaker configured to create an audio output at 360 degrees around the loudspeaker, wherein the audio output is characterized by a volume output response that varies, relative to an average loudspeaker volume response determined at 360 degrees around the loudspeaker, at different frequencies across a loudspeaker output frequency range, wherein the loudspeaker volume output response has a front volume versus frequency characteristic to the front of the loudspeaker, and a different off-axis volume versus frequency characteristic behind the loudspeaker;
a sensor configured to detect the location of a person either in front of the loudspeaker or behind the loudspeaker; and
a processor, responsive to the sensor, configured to cause the loudspeaker to vary the volume of the audio output of the loudspeaker relative to the loudspeaker volume output response for the detected location of the person, either in front of the loudspeaker or behind the loudspeaker,
wherein the volume variation of the loudspeaker is indirectly related, across the loudspeaker output frequency range, to one of either the front volume versus frequency characteristic of the loudspeaker or the off-axis volume versus frequency characteristic of the loudspeaker, depending on whether the person is in front of the loudspeaker or behind the loudspeaker, respectively.
