Patent ID: 8824709

Claim:
A system for generating left and right virtual sound sources from two or more audio inputs using a speaker array, comprising: a speaker array including a plurality of speakers; a spatial sound processor coupled to receive the audio inputs, and configured to generate the left and right virtual sound sources, including a first stage configured to generate left and right sound source positioning signals associated with the left and right virtual sound sources, the first stage including for each audio input, left and right pre-filters configured to filter the audio input based on a predetermined spatial cueing function, and provide respective left and right spatial cueing signals; and left and right first stage mixers configured to mix respective left and right spatial cueing signals from the left and right pre-filters, and generate the left and right sound source positioning signals; and a second stage coupled to receive the left and right sound source positioning signals, and configured to generate for each speaker a corresponding speaker driver signal associated with the left and right virtual sound sources, the second stage including, for each speaker, left and right array filters configured to respectively filter the left and right sound source positioning signals, and provide left and right beamforming signals associated with the left and right virtual sound sources, and a second stage mixer configured to mix the left and right beamforming signals to generate the speaker driver signal for the associated speaker; wherein the speaker array is responsive to the speaker driver signal for each speaker of the speaker array to generate the left and right virtual sound sources.
