Method to expedite playing of binaural sound to a listener

1. A method, comprising:

transmitting, during an electronic communication between a first user and a second user, a voice of the first user to a server;

processing, during the electronic communication and with the server before the voice is transmitted to the second user, the voice of the first user into binaural sound with customized head-related transfer functions (HRTFs) of the second user;

receiving, during the electronic communication and at a portable electronic device (PED) with the second user, the voice of the first user in the binaural sound processed by the server with the customized HRTFs of the second user; and

playing, to the second user and during the electronic communication, the voice of the first user in the binaural sound processed by the server with the customized HRTFs such that the voice externally localizes to the second user outside a head of the second user.

2. The method of claim 1 further comprising:

storing the customized HRTFs at the server; and

controlling, through privacy settings of the PED of the second user, authorization as to who has access to the customized HRTFs of the second user stored at the server.

3. The method of claim 1 further comprising:

rejecting playing the voice of the first user in the binaural sound and instead playing the voice of the first user in stereo sound or mono sound in response to determining the first user is not authorized to play the binaural sound to the second user.

4. The method of claim 1 further comprising:

determining, in response to the first user commencing the electronic communication to the second user, whether the first user has access privilege to the customized HRTFs of the second user.

5. The method of claim 1 further comprising:

determining, in response to the first user commencing the electronic communication to the second user, whether the first user has access privilege to the customized HRTFs of the second user;

processing the voice of the first user with the customized HRTFs when the first user has the access privilege; and

denying access to the customized HRTFs when the first user does not have the access privilege.

6. The method of claim 1 further comprising:

storing the customized HRTFs of the second user at the server; and

receiving, at the PED with the second user, input from the second user that identifies who has access to the customized HRTFs of the second user stored at the server.

7. The method of claim 1 further comprising:

storing a list of people that have privilege to the customized HRTFs of the second user;

determining, from the list and in response to the first user commencing the electronic communication with the second user, whether the first user is on the list and has the privilege to the customized HRTFs of the second user; and

processing the voice of the first user with the customized HRTFs of the second user in response to determining the first user is on the list.

8. A method, comprising:

processing, with one or more servers and during an electronic communication between a first user and a second user, a voice of the first user into binaural sound with customized head-related transfer functions (HRTFs) of the second user;

transmitting, to a portable electronic device (PED) of the second user and during the electronic communication between the first user and the second user, the voice of the first user in the binaural sound that was processed by the one or more servers with the customized HRTFs of the second user; and

playing, during the electronic communication and with the PED of the second user, the voice of the first user in the binaural sound that was processed by the one or more servers with the customized HRTFs of the second user.

9. The method of claim 8 further comprising:

storing, at the one or more servers, the customized HRTFs of the second user and a list of who has access privileges to the customized HRTFs of the second user.

10. The method of claim 8 further comprising:

determining, by the one or more servers and in response to the first user commencing the electronic communication with the second user, whether the first user has authorization to have sound processed with the customized HRTFs of the second user.

11. The method of claim 8 further comprising:

displaying, with a display of the PED of the second user, privacy settings that enable the second user to control which users are authorized to have sound processed with the customized HRTFs of the second user.

12. The method of claim 8 , wherein the first user is a computer program of a virtual reality (VR) software game or an augmented reality (AR) software game, the second user is a person, and the PED of the second user is one of a head mounted display (HMD) or electronic glasses.

13. The method of claim 8 further comprising:

determining whether the second user provided authorization to the first user to access the customized HRTFs of the second user;

processing the voice of the first user with the customized HRTFs of the second user in response to determining that the second user provided the authorization to the first user to access the customized HRTFs of the second user; and

playing the voice of the first user in stereo sound or mono sound in response to determining that the second user did not provide the authorization to the first user to access the customized HRTFs of the second user.

14. The method of claim 8 , wherein a PED of the first user and the PED of the second user are one of a head mounted display and electronic glasses, the voice of the first user transmits to the one or more servers for processing into the binaural sound before being transmitted to the PED of the second user, and the one or more servers store the customized HRTFs of the second user.

15. An electronic system, comprising:

a first portable electronic device (PED) of a first user that includes a microphone that captures a voice of the first user and a transmitter that transmits the voice of the first user to one or more servers that processes the voice of the first user with customized head-related transfer functions (HRTFs) of a second user into binaural sound; and

a second PED of the second user that includes a receiver that receives the voice of the first user in the binaural sound processed with the customized HRTFs of the second user by the one or more servers and one or more speakers that play the voice of the first user in the binaural sound that externally localizes outside a head of the second user, wherein the first PED and the second PED include head mounted displays (HMDs) and electronic glasses.

16. The electronic system of claim 15 , wherein the one or more servers determine whether the first user has access privileges to the customized HRTFs of the second suer before processing the voice of the first user in the binaural sound with the customized HRTFs of the second user.

17. The electronic system of claim 15 , wherein the one or more servers store the customized HRTFs of the second user and store access privileges that include whether the first PED of the first user has rights to the customized HRTFs of the second user.

18. The electronic system of claim 15 , wherein the second PED of the second user includes a memory that stores instructions that when executed determine whether the second user authorized the voice of the first user to play in the binaural sound.

19. The electronic system of claim 15 , wherein the one or more servers change the voice of the first user from being played to the second user in the binaural sound to being played to the second user in one of mono sound and stereo sound in response to determining that the first user does not have access privilege to the customized HRTFs of the second user.

20. The electronic system of claim 15 , wherein the second PED of the second user includes a display that displays privacy settings that enable the second user to select which users other than the second user have access privileges to the customized HRTFs of the second user.
