1. A method of signaling audio mixing gain in a teleconference using a Session Description Protocol (SDP), the method comprising:
receiving an input audio stream, from a 360-degree stream, including an audio mixing gain;
signaling the audio mixing gain in an SDP offer;
wherein the SDP offer comprises a first audio gain, an audio identifier associated with a first audio in the input audio stream, a second audio gain, and an overlay id associated with an overlay audio in the input audio stream; and
based on a receiver accepting the SDP offer and based on a change in the audio mixing gain, signaling only an updated audio gain instead of signaling an entire media line.
