  • Extraction of channels from multichannel signals utilizing stimulus
    Patent number: 9241230
    Abstract: An approach and device for optimizing a sound system by extracting a two-channel stereo source out of a set of multiple channels with unknown frequency responses, crosstalk, time delays and sample rate by employing a digital test sequence that utilizes maximum-length-sequences (MLS) that is fed into the sound system and results in a reconstructed stereo source that may be further used as an input to a signal processor that performs improved speaker and room equalization.
    Type: Grant
    Filed: June 4, 2013
    Date of Patent: January 19, 2016
    Assignee: Harman International Industries, Incorporated
    Inventors: Ulrich Horbach, Kirk Bushen, Adam Strauss, Andy Wehmeyer
