Harman International Industries Assigned Patent for Multiband Ducker
ALEXANDRIA, Va., Nov. 11 -- Harman International Industries, Stamford, Connecticut, has been assigned a patent (9,813,039) developed by James M. Kirsch, Salt Lake City, for a multiband ducker. The abstract states: "A multiband ducker is configured to duck a specific range of frequencies within a music signal in proportion to a corresponding range of frequencies within a speech signal, and then combine the ducked music signal with the speech signal for output to a user. In doing so, the multiband ducker separates the music signal into different frequency ranges, which may include low, middle, and high-range frequencies. The multiband ducker then reduces the amplitude of the specific range of frequencies found in the speech signal, typically the mid-range frequencies. When the ducked music signal and the speech signal are combined, the resultant signal includes important frequencies of the original music signal, including low-range and high-range, thereby allowing perception of the music signal to continue in relatively uninterrupted fashion. Additionally, the combined signal also includes the speech signal, allowing for the perception of intelligible speech concordant with the perception of music."
The patent application was filed on Sept. 15, 2014 (14/486,451). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=9,813,039.PN.&OS=PN/9,813,039&RS=PN/9,813,039
