Abstract
A method processes binaural sound to externally localize to a first user at a first location. This location is shared such that an electronic device processes the binaural sound to externally localize to a second user at a second location. The first and second locations occur at a same or similar location such that the first and second users hear the binaural sound as originating from the same or similar location.

21. A method executed by one or more electronic devices, the method comprising:
-
convolving, with a first digital signal processor (DSP) in first headphones worn by a first user, sound with first head-related transfer functions (HRTFs) having first coordinates that define a location with respect to the first user; transmitting, from the first headphones worn by the first user to second headphones worn by a second user, the first coordinates; determining, from the first coordinates that define the location with respect to the first user, second coordinates that define the location with respect to the second user; and convolving, with a second DSP in the second headphones worn by the second user, the sound with second HRTFs having the second coordinates that define the location with respect to the second user, wherein the sound externally localizes to both the first and second users at a same location. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A non-transitory computer-readable storage medium storing instructions that one or more electronic devices execute to share locations where sound externally localizes to listeners, the method comprising:
-
processing, with a first wearable electronic device worn by a first listener and with first head-related transfer functions (HRTFs), sound that externally localizes as binaural sound to a location at least one meter away from a head of the first listener; sharing, with a second wearable electronic device worn by a second listener, a first coordinate location that defines the location with respect to the head of the first listener; calculating, from the first coordinate location, a second coordinate location that defines the location with respect to a head of the second listener; and processing, with the second wearable electronic device worn by the second listener and with second HRTFs, the sound that externally localizes as the binaural sound to the location at least one meter away from the head of the second listener such that the first and second listeners hear the binaural sound originating from a same location. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A method comprising:
-
improving playing of binaural sound to a first user wearing a first wearable electronic device (WED) and second user wearing a second WED who are both situated in a room by; processing, with a first digital signal processor (DSP) and with first head-related transfer functions (HRTFs) having first coordinates, sound that externally localizes in the room as the binaural sound to a location that is a first sound localization point (SLP) having the first coordinates with respect to a head of the first user; sharing the first SLP with at least one of the second WED and a computer in communication with the first and second WEDs; determining, from the coordinates of the first SLP, a second SLP having second coordinates with respect to a head of the second user; determining, from the second SLP, second HRTFs having the second coordinates; and processing, with a second DSP and with the second HRTFs having the second coordinates, the sound that externally localizes in the room as the binaural sound to the location such that the first and second users hear the binaural sound originating from a same location in the room. - View Dependent Claims (36, 37, 38, 39, 40)
