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 6):
A compressor architecture for enhancing the low frequency response of a loudspeaker, the architecture comprising:\n an equalizer configured to shape the input audio frequency response for the desired amount of bass boost or cut; a crossover network to divide the low band into two bands, the first band being the upper low band and the second band being the lower low band; a compressor for processing the first band configured to produce output signals responsive to the energy level of the low frequency portion of the input audio signal; a compressor for processing the second band configured to produce output signals responsive to the energy level of the lower low frequency portion of the input audio signal; a high pass filter configured to remove frequencies that cannot be reproduced by the loudspeaker; a summer to recombine first and second bands with the middle and high band portion of the audio signal; and a soft clipper to limit brief signal excursions into the distortion region of the loudspeaker.
