Claim 5:
6. An audio system for enhanced listener localization of played-back sound comprising:
an audio recording comprising four channels comprising a left main audio recorded channel, a right main audio recorded channel, a left side localization audio recorded channel and a right side localization audio recorded channel;
an audio source adapted to play back the audio recording comprising four channels;
a right main loudspeaker connected to the audio source and adapted to transduce sound corresponding to the right main audio recorded channel;
a left main loudspeaker connected to the audio source and adapted to transduce sound corresponding to the left main audio recorded channel;
a right side localization loudspeaker connected to the audio source and adapted to transduce sound corresponding to the right side localization audio recorded channel; and
a left side localization loudspeaker connected to the audio source and adapted to transduce sound corresponding to the left side localization audio recorded channel;
wherein the sound transduced by the right side localization loudspeaker and the left side localization loudspeaker is low-pass filtered to enhance localization by a listener, and
wherein a low-pass filtering of the sound transduced by the right side localization loudspeaker and the left side localization loudspeaker is previously applied to the audio recording and stored in the left side localization audio recorded channel and the right side localization audio recorded channel.
