7. The method of claim 1 further comprising:

receiving, at the electronic device of the second user and from the electronic device of the first user, azimuth and elevation coordinates that indicate the first location selected by the first user where the binaural sound will externally localize to the second user; and

expediting playing of the binaural sound to the second user by processing, with a digital signal processor (DSP) and before the second user activates the emoji to hear the binaural sound, the binaural sound with a pair of head-related transfer functions (HRTFs) that have coordinates equal to the azimuth and elevation coordinates received from the electronic device of the first user.

8. A non-transitory computer-readable storage medium storing instructions that one or more electronic devices execute in a computer system in which a first person with a first portable electronic device (PED) communicates with a second person with a second PED, the method comprising:

receiving, at the second PED and from the first PED, a first location where binaural sound will externally localize to the second person upon activation of an emoji;

displaying, with the second PED, the emoji that shows the first location where the binaural sound will externally localize to the second person upon activation of the emoji;

receiving, at the second PED and from the second person, an instruction that changes the first location to a second location where the binaural sound will externally localize to the second person upon activation of the emoji; and

playing, with the second PED and upon activation of the emoji, the binaural sound that originates to the second person at a sound localization point (SLP) at the second location.

9. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

displaying, with the second PED, the emoji that shows the second location where the binaural sound will externally localize to the second person upon activation of the emoji.

10. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

determining azimuth and elevation coordinates for where the second location is located on a display of the second PED;

obtaining a pair of head related transfer functions (HRTFs) that have azimuth and elevation coordinates equal to the azimuth and elevation coordinates for where the second location is located on the display of the second PED; and

processing, with a digital signal processor and upon activation of the emoji, sound with the HRTFs to generate the binaural sound that originates to the second person at the SLP.

11. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

displaying, on the second PED, an image that represents the second person; and

displaying, on the second PED, the emoji at a location with respect to the image to display where the binaural sound will externally localize relative to the second person upon activation of the emoji.

12. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

receiving, at the second PED and from the first PED, azimuth and elevation coordinate locations that provide the first location where the binaural sound will externally localize to the second person upon activation of the emoji, wherein the second PED displays the emoji at the azimuth and elevation coordinate locations to display where the binaural sound will externally localize with respect to a head of the second person.

13. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

expediting playing of the binaural sound to the first location by convolving, before the second person activates the emoji to hear the binaural sound, sound of the emoji into the binaural sound with a pair of head-related transfer functions (HRTFs) with azimuth and elevation coordinates equal to azimuth and elevation coordinates of the first location.

14. The non-transitory computer-readable storage medium of claim 8 storing the instructions that execute such that the method further comprises:

displaying, with the second PED, an image that represents a head of the second person with the emoji displayed at the first location with respect to the head of the second person to provide a visual indication for the SLP.

15. A method comprising:

improving an electronic communication between a first user with a portable electronic device (PED) and a second user with a PED by:

displaying, with the PED of the second user, an emoji with a visual indication that shows a first location where binaural sound will externally localize outside a head of the second user, the first location being provided by the first user;

moving, with the PED of the second user and in response to a command from the second user, the visual indication to change the first location to a second location where the binaural sound will externally localize outside the head of the second user; and

processing, with a digital signal processor (DSP) and in response to activation of the emoji after moving the visual indication, sound of the emoji with one or more pairs of head-related transfer functions (HRTFs) to provide the sound of the emoji as the binaural sound that externally localizes outside the head of the second user to the second location.

16. The method of claim 15 further comprising:

processing, with the DSP and in response to activation of the emoji before moving the visual indication, the sound of the emoji with HRTFs to provide the sound of the emoji as the binaural sound that externally localizes outside the head of the second user to the first location, wherein the PED of the second user plays the binaural sound to the first location outside the head of the second user before moving the visual indication and plays the binaural sound to the second location outside the head of the second user after moving the visual indication.

17. The method of claim 15 further comprising:

expediting playing of the binaural sound to the second user by processing, with the DSP, the sound of the emoji with HRTFs having azimuth and elevation coordinates corresponding to the first location in anticipation of receiving a command by the second user to play the binaural sound at the first location.
