US Patent:

20130097510, Apr 18, 2013

Filed:

Aug 22, 2012

Appl. No.:

13/592182

Inventors:

James Tracey - Laguna Niguel CA, US
Daekyoung Noh - Newport Beach CA, US

Assignee:

DTS LLS - CALABASAS CA

International Classification:

G06F 3/16

US Classification:

715727

Abstract:

An audio adjustment system is provided that can output a user interface customized by the provider of the audio system instead of the electronic device manufacturer. Such an arrangement can save both field engineers and manufacturers a significant amount of time. Advantageously, in certain embodiments, such an audio adjustment system can be provided without knowledge of the electronic device's firmware. Instead, the audio adjustment system can communicate with the electronic device through an existing audio interface in the electronic device to enable a user to control audio enhancement parameters in the electronic device. For instance, the audio adjustment system can control the electronic device via an audio input jack on the electronic device.

Appl. No.:

17/269159

Inventors:

- Calabasas CA, US
Daekyoung Noh - Huntington Beach CA, US

International Classification:

H04S 7/00
H04R 3/04

Abstract:

A loudspeaker system can include a first loudspeaker driver provided in a substantially fixed spatial relationship relative to a microphone. The loudspeaker driver can be tuned, for example automatically and without user input. In an example, the tuning can include receiving transfer function reference information about the first loudspeaker driver and the microphone, and receiving information about a desired acoustic response for the loudspeaker system. The tuning can include determining a simulated response for the loudspeaker system using a first input signal and the transfer function reference information, and can include providing the first input signal to the first loudspeaker driver. In response to the first input signal, an actual response for the loudspeaker driver can be received using the microphone. A compensation filter can be determined for the loudspeaker system based on the determined simulated response and the received actual response for the loudspeaker system.

International Classification:

H04S 7/00
G06T 7/73

Abstract:

Systems and methods discussed herein can provide three-dimensional audio virtualization with sweet spot adaptation. In an example, an audio processor circuit can be used to update audio signals for sweet spot adaptation based on information from at least one depth sensor or camera about a listener position in a listening environment.

International Classification:

H04S 7/00
H04S 3/00

Abstract:

Systems and methods can provide an elevated, virtual loudspeaker source in a three-dimensional soundfield using loudspeakers in a horizontal plane. In an example, a processor circuit can receive at least one height audio signal that includes information intended for reproduction using a loudspeaker that is elevated relative to a listener, and optionally offset from the listener's facing direction by a specified azimuth angle. A first virtual height filter can be selected for use based on the specified azimuth angle. A virtualized audio signal can be generated by applying the first virtual height filter to the at least one height audio signal. When the virtualized audio signal is reproduced using one or more loudspeakers in the horizontal plane, the virtualized audio signal can be perceived by the listener as originating from an elevated loudspeaker source that corresponds to the azimuth angle.

International Classification:

H04S 7/00
H04R 5/04
H04S 3/00

Abstract:

The methods and apparatus described herein provides technical solutions to the technical problems facing crosstalk cancellation for 3D audio virtualization. One technical solution includes preconditioning audio signals based on crosstalk canceller characteristics and based on characteristics of sound sources at intended locations in 3D space. To provide these technical solutions, the systems and methods described herein include an audio virtualizer and an audio preconditioner. In particular, the audio virtualizer includes a crosstalk canceller, and the audio preconditioner preconditions audio signals based on characteristics of a crosstalk cancellation system and based on characteristics of a binaural synthesis system or intended input source location in space. This solution improves the overall accuracy of virtualization of 3D sound sources and reduces or eliminates audio artifacts such as incorrect localization, inter-channel sound level imbalance, or a sound level that is higher or lower than intended.
