Patent number: 10299040Abstract: 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.Type: GrantFiled: November 13, 2017Date of Patent: May 21, 2019Assignee: DTS, Inc.Inventors: Sarah Yang, Richard J. Oliver, Robert C. Maling, III, Aaron Warner

Patent number: 10243534Abstract: Systems and methods to provide an audio spectral correction can be implemented in a variety of applications. Such systems and methods can include an equalizer design that uses efficient filter sections tuned with a closed form algorithm to give an accurate and intuitive frequency response with low complexity and minimal processing overhead. Embodiments can enable efficient and accurate control of reverberation time vs. frequency in artificial reverberators. Embodiments can enable efficient realization of a cascade combination of multi-band equalization functions as a single multi-band equalizer function, in which such functions can be expressed as graphic equalization functions using the same set of center frequencies as the cascade combination of multi-band equalization functions. Additional apparatus, systems, and methods are disclosed.Type: GrantFiled: October 28, 2016Date of Patent: March 26, 2019Assignee: DTS, Inc.Inventors: Jean-Marc Jot, Richard J. Oliver

Patent number: 8428276Abstract: In certain embodiments, an improved audio equalization filter can be generated by frequency warping one or more digital filters having a plurality of frequency bands. Frequency warping can include, for example, transforming at least some of the frequency bands of the one or more digital filters into lower frequency bands. As a result, in various implementations the audio equalization filter may be more accurate than certain currently-available IIR equalization filters. The audio equalization filter may also be more computing-resource efficient than certain currently-available FIR equalization filters.Type: GrantFiled: June 29, 2010Date of Patent: April 23, 2013Assignee: DTS LLCInventor: Richard J.

Patent number: 8386247Abstract: An adaptive audio system can be implemented in a communication device. The adaptive audio system can enhance voice in an audio signal received by the communication device to increase intelligibility of the voice. The audio system can adapt the audio enhancement based at least in part on levels of environmental content, such as noise, that are received by the communication device. For higher levels of environmental content, for example, the audio system might apply the audio enhancement more aggressively. Additionally, the adaptive audio system can detect substantially periodic content in the environmental content. The adaptive audio system can further adapt the audio enhancement responsive to the environmental content.Type: GrantFiled: June 18, 2012Date of Patent: February 26, 2013Assignee: DTS LLCInventors: Jun Yang, Richard J.

Patent number: 7522733Abstract: Reproduction of stereophonic audio information over a single speaker requires summing multiple stereo channels. When signals having approximately equal magnitudes and approximately opposite phases at a frequency are added together, the audio information at the frequency is lost. To preserve areas of potential cancellation and potential audio information loss, the audio enhancement system adjusts the phase relationship between the stereophonic channels. To avoid the loss of the spatial content of the stereo signal, the audio enhancement system determines the difference information that exists between different stereophonic channels. The audio enhancement system enhances the difference information and mixes the enhanced difference information with the phase adjusted signals to generate an enhanced monophonic output.Type: GrantFiled: December 12, 2003Date of Patent: April 21, 2009Assignee: SRS Labs, Inc.Inventors: Alan Kraemer, Richard J.

Patent number: 6441830Abstract: A method and apparatus for storing digitized audio/video tracks. A plurality of lists are created wherein each of the plurality of lists defines a characteristic of the audio/visual data. The plurality of lists are linked according to a data structure such that performing an edit operation on a portion of the audio/visual data results in the edit operation being applied to the plurality of lists.Type: GrantFiled: September 24, 1997Date of Patent: August 27, 2002Assignees: Sony Corporation, Sony Pictures Entertainment, Inc.Inventors: Roger M.

Patent number: 6393517Abstract: A method of recording data, including audio data and control data, to a SCSI drive having both a write mode and a write-verify mode, comprises the steps of initializing the drive to a write mode, receiving recording data and organizing the recording data into SCSI request blocks (SRBs), and checking each SRB to see if it contains a write block. If the SRB includes either no write block or is audio data, then the SRB is recorded by the drive. However, if the SRB includes a write block and no audio data, then the SRB is converted from a write block to a write-verify block and recorded by the drive.Type: GrantFiled: August 31, 1999Date of Patent: May 21, 2002Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Richard J.
