A method of formatting media during a group communication session, comprising: receiving, during the group communication session, one dimensional, 1D, audio media from a first set of access terminals that belong to a communication group, wherein the received audio media corresponds to content for presentation to a second set of access terminals that belong to the communication group; determining relative physical or geographical location information associated with at least two access terminals comprising an access terminal from the first set of access terminals and an access terminal from the second set of access terminals; selectively formatting the received media for presentation to the second set of access terminals by converting the 1D audio media into three- dimensional, 3D, audio media based on the determined relative physical or geographical location information; wherein the selectively formatting step includes: selecting, for a given access terminal among the second set of access terminals, a virtual origination point or direction for at least one access terminal among the first set of access terminals, the selected direction and the direction of the selected virtual origination point differing from the direction of the actual physical location of said access terminal among the first set of access terminals, but being used to convey relative physical or geographical information for said access terminal among the first set of access terminals; and configuring, for the given access terminal among the second set of access terminals, at least one three-dimensional audio output frame to include the audio media of the at least one access terminal among the first set of access terminals as being positioned at the selected virtual origination point or direction. receiving, during the group communication session, one dimensional, 1D, audio media from a first set of access terminals that belong to a communication group, wherein the received audio media corresponds to content for presentation to a second set of access terminals that belong to the communication group; determining relative physical or geographical location information associated with at least two access terminals comprising an access terminal from the first set of access terminals and an access terminal from the second set of access terminals; selectively formatting the received media for presentation to the second set of access terminals by converting the 1D audio media into three- dimensional, 3D, audio media based on the determined relative physical or geographical location information; wherein the selectively formatting step includes: selecting, for a given access terminal among the second set of access terminals, a virtual origination point or direction for at least one access terminal among the first set of access terminals, the selected direction and the direction of the selected virtual origination point differing from the direction of the actual physical location of said access terminal among the first set of access terminals, but being used to convey relative physical or geographical information for said access terminal among the first set of access terminals; and configuring, for the given access terminal among the second set of access terminals, at least one three-dimensional audio output frame to include the audio media of the at least one access terminal among the first set of access terminals as being positioned at the selected virtual origination point or direction. selecting, for a given access terminal among the second set of access terminals, a virtual origination point or direction for at least one access terminal among the first set of access terminals, the selected direction and the direction of the selected virtual origination point differing from the direction of the actual physical location of said access terminal among the first set of access terminals, but being used to convey relative physical or geographical information for said access terminal among the first set of access terminals; and configuring, for the given access terminal among the second set of access terminals, at least one three-dimensional audio output frame to include the audio media of the at least one access terminal among the first set of access terminals as being positioned at the selected virtual origination point or direction.
