Claim:
1. A method for producing multi-dimensional sound from a speaker array, comprising: receiving a plurality of audio signals from a plurality of sources; filtering each audio signal through each of a left Head-Related Transfer Function (HRTF) and a right HRTF to generate HRTF-filtered left and HTRF-filtered right audio signals, wherein the left HRTF is calculated based on an angle at which the plurality of audio signals will be transmitted to a left ear of a user, and wherein the right HRTF is calculated based on an angle at which the plurality of audio signals will be transmitted to a right ear of a user; filtering each of the HRTF-filtered left and HRTF-filtered right audio signals with a Psychoacoustic Bandwidth Extension Processor (PBEP); merging the PBEP HRTF-filtered left audio signals into a left total binaural signal; merging the PBEP HRTF-filtered right audio signals into a right total binaural signal; filtering the left total binaural signal through a set of left spatialization filters, wherein a separate left spatialization filter is provided for each speaker in the speaker array; filtering the right total binaural signal through a set of right spatialization filters, wherein a separate right spatialization filter is provided for each speaker in the speaker array; summing the filtered left total binaural signal and filtered right total binaural signal for each respective speaker into a speaker signal; feeding the speaker signal to the respective speaker in the speaker array; and transmitting the speaker signal through the respective speaker to the user.
