Abstract
Aspects of the present disclosure relate to a method and system for processing an audio signal to optimize the localization of sound in a sound system using a head related transfer function HRTF). A location of a user is determined and a speaker is driven with a waveform representing a location specific cue having a desired user response. The location specific cue is associated with a defined HRTF for the determined location of the user. A user response to location specific cue is detected and compared to the location specific cue. The defined HRTF is then updated with information from the comparison of the user response to the location specific cue.
Claims18
A method for determining an optimal Head-Related Transfer Function the method comprising;
- a) determining a location of a user and a defined Head-Related Transfer Function (HRTF) for the user, wherein the user is provided images of heads associated with different HRTFs and the user is prompted to choose an image of a head that closely matches their own;
- b) driving a speaker with a waveform representing a location specific cue having a desired user response wherein the location specific cue is associated with the defined HRTF for the determined location of the user, wherein the location specific cue is a panned sound source and the desired user response is a change in orientation of the user towards a virtual location of the panned sound source;
- c) detecting a user response to location specific cue;
- d) analyzing user response in comparison to location specific cue;
- and
- e) updating the defined HRTF with information from the comparison of the user response and the location specific cue.
A non-transitory computer readable medium having embodied thereon instructions, the instructions when executed by a processor cause the processor to carry out the method for determining an optimal Head-Related Transfer Function the method comprising:
- a) determining a location of a user and a defined Head-Related Transfer Function (HRTF) for the user, wherein the user is provided images of heads associated with different HRTFs and the user is prompted to choose an image of a head that closely matches their own;
- b) play a location specific cue having a desired user response wherein the location specific cue is associated with the defined HRTF for the determined location of the user, wherein location specific cue is a panned sound source and the desired user response is a change in orientation of the user towards a virtual location of the panned sound source;
- c) detect a user response to location specific cue;
- d) analyze user response in comparison to location specific cue;
- and
- e) update the defined HRTF with information from the comparison of the user response and the location specific cue.
A system, comprising:
- a processor,
- a memory coupled to the processor, the memory having executable instructions embodied therein, the instructions being configured to cause the processor to carry out a method when executed, the method comprising;
- a) determining a location of a user and a defined Head-Related Transfer Function (HRTF) for the user, wherein the user is provided images of heads associated with different HRTFs and the user is prompted to choose an image of a head that closely matches their own;
- b) play a location specific cue having a desired user response wherein the location specific cue is associated with the defined HRTF for the determined location of the, wherein location specific cue is a panned sound source and the desired user response is a change in orientation of the user towards a virtual location of the panned sound source;
- c) detect a user response to location specific cue;
- d) analyze user response in comparison to location specific cue;
- and
- e) update the defined HRTF with information from the comparison of the user response and the location specific cue.
