Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC G  H

Claim 14:
15. A tangible, non-transitory computer-readable medium comprising instructions for producing an audio output, wherein the instructions, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving a source stream of audio content having at least a left input channel signal and a right input channel signal;
generating a sum input signal based on a sum of the left and right input channel signals;
generating a difference input signal based on a difference of the left and right input channel signals;
providing the sum input signal to a first plurality of spatial filters to generate first spatial filter output signals;
providing the difference input signal to a second plurality of spatial filters to generate second spatial filter output signals, wherein the first plurality of spatial filters and the second plurality of spatial filters are separate distinct spatial filters;
combining the first spatial filter output signals and the second spatial filter output signals to produce a plurality of audio output signals such that each of the plurality of audio output signals is based on both at least one of the first spatial filter output signals and at least one of the second spatial filter output signals; and
providing the plurality of audio output signals to a plurality of audio transducers.
