1. A method performed by a first electronic device, the method comprising:
receiving, over a communication data link and from a second electronic device, a speech signal and a sound-object sonic descriptor having metadata that describes a sound object that are associated with a communication session between both devices, wherein the speech signal and the sound-object sonic descriptor are sent based on bandwidth availability of the second electronic device;
using the metadata to produce a reproduction of the sound object comprising an audio signal and position data that indicates a position of a virtual sound source of the sound object;
spatially rendering the audio signal according to the position data to produce a plurality of binaural signals; and
mixing the speech signal with the plurality of binaural signals to produce a plurality of mixed signals to drive a plurality of speakers.
