Abstract
A personalized HRTF is generated from a generic HRTF by having a person don headphones, then select a generic HRTF model from a list. Test signals emulating sounds from a source at a specific virtual speaker location are played on the headphones, and the person indicates where he thinks the emulated sounds are coming from. Any difference between the virtual speaker location and the “heard” location is used to adjust the parameters (amplitude, phase, and frequency response) of the generic HRTF to render a HRTF personalized to the listening person.
Claims17
An apparatus comprising:
- at least one processor configured with instructions to:
- receive indication of a perceived origin of sound played on a headphone;
- identify a virtual location from whence the sound is emulated to originate;
- and
- based on the perceived origin and the virtual location, alter a first head related transfer function (HRTF) selected from plural HRTFs to establish a personalized HRTF for a person making the indication, the plural HRTFs being associated with respective speaker setups.
An apparatus comprising:
- at least one processor configured with instructions to:
- receive indication of a perceived origin of sound played on a headphone;
- identify a virtual location from whence the sound is emulated to originate;
- based on the perceived origin and the virtual location, alter a first head related transfer function (HRTF) to establish a personalized HRTF for a person making the indication;
- and
- present on a display at least one user interface (UI) configured to allow selection of the first HRTF from among plural HRTFs.
A method comprising:
- identifying a first head related transfer function (HRTF) based on user selection of the first HRTF;
- identifying an emulated origination of sound played on headphones;
- identifying a perceived origination of the sound played on the headphones;
- and
- based at least in part on a difference between the emulated origination and perceived origination, modifying the first HRTF.
A consumer electronics (CE) device comprising:
- at least one display;
- at least one processor configured with instructions to:
- receive user selection of a first head related transfer function (HRTF);
- play sound on headphones emulated to be from a virtual origination;
- receive at least one user indication of an origination of sound;
- present on the display a first selector selectable to adjust the first HRTF to alter the first HRTF according to the user indication of the origination of sound relative to the virtual origination;
- alter the first HRTF based at least in part on a difference between the virtual origination and the origination of sound indicated by the user to render a personalized HRTF;
- and
- generate audio using the personalized HRTF.
