Methods Of Using Head Related Transfer Function (Hrtf) Enhancement For Improved Vertical- Polar Localization In Spatial Audio Systems

View page
US Patent:
20130202117, Aug 8, 2013
Filed:
Mar 15, 2013
Appl. No.:
13/832831
Inventors:
Government of the United States as Represented by the Secretary of the Air Force - Wright-Patterson AFB OH, US
Griffin D. Romigh - Beloit OH, US
Assignee:
Government of the United States as Represented by the Secretary of the Air Force - Wright-Patterson AFB OH
International Classification:
H04R 5/04
US Classification:
381 17
Abstract:
A method of enhancing vertical polar localization of a head related transfer function (HRTF). The method includes splitting an audio signal and generating left and right output signal by enhancing a left lateral magnitude of the respective signal by determining a log lateral component of the respective frequency-dependent audio gain that is equal to a median log frequency-dependent audio gain for all audio signals of that channel having an desired one of the plurality of perceived source locations. A vertical magnitude of the respective audio signal is enhanced by determining a log vertical component of the respective frequency-dependent audio gain that is equal to a product of a first enhancement factor and a difference between the respective frequency-dependent audio gain at the desired one of the plurality of perceived source locations and the lateral magnitude of respective audio signal. The output signals are time delayed according to an interaural time and delivered to left and right ears of a listener.

Head Related Transfer Function (Hrtf) Enhancement For Improved Vertical-Polar Localization In Spatial Audio Systems

US Patent:
8428269, Apr 23, 2013
Filed:
May 20, 2010
Appl. No.:
12/783589
Inventors:
Douglas S. Brungart - Rockville MD, US
Griffin D. Romigh - Pittsburgh PA, US
Assignee:
The United States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:
H04S 5/00
H04R 5/02
US Classification:
381 17, 381 18, 381 19, 381 61, 381 74, 381310, 381309, 340974, 340975, 340976, 340963, 704250, 704246, 7042001, 7045001
Abstract:
A spatial audio system for implementing a head-related transfer function (HRTF). A first stage implements a lateral HRTF that reproduces the median frequency response for a sound source located at a particular lateral distance from a listener, and second stage implements a vertical HRTF that reproduces the spectral changes when the vertical distance of a sound source changes relative to the listener. The system improves the vertical localization accuracy provided by an arbitrary measured HRTF by introducing an enhancement factor into the second processing stage. The enhancement factor increases the spectral differentiation between simulated sound sources located at different positions within the same “cone of confusion. ”.

Collaborative Personalization Of Head-Related Transfer Function

US Patent:
20180310115, Oct 25, 2018
Filed:
Apr 19, 2018
Appl. No.:
15/957876
Inventors:
- Wright-Patterson AFB OH, US
Griffin D. Romigh - Dayton OH, US
Assignee:
Government of the United States, as represented by the Secretary of the Air Force - Wright-Patterson AFB OH
International Classification:
H04S 7/00
H04S 3/00
Abstract:
An improved methodology for binaural rendering of audio signals that are perceived by a user to originate from a real-world spatial location is disclosed. Embodiments enable personalized HRTF selection from among a data store containing a plurality of candidate HRTFs using an evaluation-based personalization strategy. One or more relational models personalize the selection. These relational models can relate candidate HRTFs to each other and a particular user to other users so that only a subset of the candidate HRTFs require evaluation. Candidate HRTFs can be evaluated according to one or more selection policies, and relational models can be updated based on actual responses from a user to virtual audio signals that are rendered by a candidate HRTF.

US Patent:
20170164085, Jun 8, 2017
Filed:
Feb 16, 2017
Appl. No.:
15/434818
Inventors:
- Wright-Patterson AFB OH, US
Griffin D. Romigh - Beavercreek OH, US
Assignee:
Government of the United States as Represented by the Secretary of the Air Force - Wright-Patterson AFB OH
International Classification:
H04R 5/00
Abstract:
A Head-Related Transfer Function. The Head-Related Transfer Function includes listener-specific and general components. The listener-specific component includes listener-specific, vertical variations in the Head-Related Transfer Function. The general component includes non-listener-specific, lateral variations in the Head-Related Transfer Function.

US Patent:
20150156599, Jun 4, 2015
Filed:
Dec 4, 2014
Appl. No.:
14/560792
Inventors:
- Wright-Patterson AF OH, US
Griffin D. Romigh - Beavercreek OH, US
Assignee:
Government of the United States as Represented by the Secretary of the Air Force - Wright-Patterson AFB OH
International Classification:
H04S 5/00
Abstract:
A method generating a virtual audio signal for a listener. The method includes estimating spherical harmonic coefficients based on an individual character of the listener. The estimated spherical harmonic coefficients are compared to a distribution of known spherical harmonic coefficients. The estimated spherical harmonic coefficients are iteratively updated and compared to the distribution of known spherical harmonic coefficients until convergence. The individual character and the converged spherical harmonic coefficients are then applied to a mono-channel sound.
