A universal four-channel multimedia computer speaker system is connectable to
audio
sub-system control circuits (e.g., "sound cards") of both the four-channel type
and the conventional two-channel (stereo) type. With the audio sub-system control
circuit being of a four-channel type, the universal four-channel audio system functions
as a conventional multimedia computer four-channel surround sound audio system.
With a four audio channel multimedia computer work and the audio sub-system control
circuit being of a conventional two-channel (stereo) type, the universal four-channel
audio system is configured to provide one pair of wide-band speakers (e.g., the
front) with distinct audio playback according to respective right-front and left-front
audio channels in a four or two audio channel multimedia computer work such as
a game, music, etc. The universal four-channel audio system is configured to provide
at the rear speakers distinct audio playback that are generated from the right-front
and left-front audio channels in the four or two audio channel multimedia computer
work. With respect to the rear speakers, the universal four-channel audio system
includes a proxy audio signal component that provides respective right and left
rear proxy audio signals to proximate the typical sound of actual right and left
rear audio signals carried on a four audio channel multimedia computer work or
simulated surround signals generated from conventional two channel multimedia work.
