US Patent:

8509464, Aug 13, 2013

Filed:

Oct 31, 2011

Appl. No.:

13/286082

Inventors:

Hideaki Kato - Yokohama, JP
Alan Kraemer - Irvine CA, US
Sarah Yang - Irvine CA, US

Assignee:

DTS LLC - Calabasas CA

International Classification:

H04R 5/02

US Classification:

381310, 381300, 381307

Abstract:

A method for processing audio signals can include applying at least one front perspective filter to each of left and right front audio signals to yield filtered left and right front output signals, where the left and right front output signals each drive a front speaker. Moreover, the method can include applying at least one rear perspective filter to each of left and right rear audio signals to yield left and right rear output signals, where the left and right rear output signals each drive a rear speaker to simulate a rear surround sound effect when positioned in front of a listener.

Appl. No.:

12/539380

Inventors:

Sarah Yang - Irvine CA, US
Richard J. Oliver - Capistrano Beach CA, US

Assignee:

DTS LLC - Calabasas CA

International Classification:

H03G 5/00
H03G 3/00

US Classification:

381103, 381107, 381109

Abstract:

A system can be provided for increasing loudness of an audio signal to present a perceived loudness to a listener that is greater than a loudness provided natively by a loudspeaker. The system can include one or more of the following: a frequency suppressor, a loudness adjuster, an equalizer, and a distortion control module. The frequency suppressor can increase headroom in the audio signal by filtering out low and/or high frequencies. The loudness adjuster can calculate a loudness of the audio signal and apply a gain to the audio signal to increase the loudness. The equalizer can further increase headroom by attenuating portions of a passband of the loudspeaker's frequency response. The distortion control module can induce partial harmonic distortion in the audio signal to further increase loudness.

Assignee:

DTS LLC - Calabasas CA

International Classification:

H04R 5/00

US Classification:

381307

Abstract:

A method for processing audio signals can include receiving left and right front audio signals and left and right rear audio signals, where the left and right rear audio signals. In addition, the method can include applying at least one front perspective filter to each of the left and right front audio signals to yield filtered left and right front output signals, where the left and right front output signals each drive a front speaker. Moreover, the method can include applying at least one rear perspective filter to each of the left and right rear audio signals to yield left and right rear output signals, where the left and right rear output signals each drive a rear speaker to simulate a rear surround sound effect when positioned in front of a listener.

International Classification:

H04R 5/02

US Classification:

381310

Abstract:

A method for processing audio signals can include receiving left and right front audio signals, where the left and right front audio signals including information about front spatial position of sound sources relative to a listener. The method can also include receiving left and right rear audio signals, where the left and right rear audio signals include information about rear spatial position of sound sources relative to a listener. In addition, the method can include applying at least one front perspective filter to each of the left and right front audio signals to yield filtered left and right front output signals, where the left and right front output signals each drive a front speaker. Moreover, the method can include applying at least one rear perspective filter to each of the left and right rear audio signals to yield left and right rear output signals, where the left and right rear output signals each drive a rear speaker to simulate a rear surround sound effect when positioned in front of a listener.
