Abstract:
Audio processing architectures are described for implementing a multi-band audio compression algorithm with advanced surround processing. Exemplary architectures can improve the fidelity and perceived sound field spread of inexpensive, cabinet mounted, stereo speakers such as those that might be found in televisions, wireless speaker systems and sound bars. Embodiments of the present disclosure can improve inexpensive, cabinet mounted, stereo speakers by providing, e.g., (i) an Advanced Surround algorithm that adds depth and height to the left/right/center sound field images, (ii) a Soft Clip algorithm to minimize the perceived artifacts caused by compressor overshoot, (iii) configurable crossover filter order adjustment to allow better isolation between bands, (iv) a compressor maximum gain adjustment to reduce overshoot and minimize noise boost, and/or (v) a center gain adjustment to emphasize the perception of the center image (dialog) in high ambient noise situations.

Claim (Index 4):
A system for generating perceived additional width, depth and height to a stereo audio signal comprising:\n a difference channel width adjustment; a difference channel feedback delay loop with output adjusted by a difference delay gain adjustment; a summer to sum the output of the width adjustment and the difference delay gain adjustment, the summer output is summed with one stereo channel and summed, phase reversed (180 degree phase shift) with the other stereo channel; and a sum channel feedback delay loop with output first adjusted by a sum delay gain adjustment and then combined with the left and right channels.
