Y.9 Recommended audio mixing gains
26.1143GPPIP Multimedia Subsystem (IMS)Media handling and interactionMultimedia telephonyRelease 18TS
An ITT4RT-Tx client may specify recommended gains for mixing of its transmitted audio streams and update these recommended gains during a session. An ITT4RT-Rx client may or may not use such recommended mixing gains to scale the audio streams prior to mixing.
An ITT4RT-Tx client may for example send the recommended mixing gains r0, r1, .., rN for the audio sources a0 (360 video) and a1, a2, .., aN (overlay videos) of that sender to recommend a mix at the receivers to be r0*a0+r1*a1+……+rN*aN.
If an ITT4RT-Rx client negotiated to receive recommended audio mixing gains and the ITT4RT-Tx client chooses to send these mixing gains, the ITT4RT-Tx client shall indicate each audio mixing gain value to the ITT4RT-Rx client using RTP header-extensions (see clause Y.9.1).
Y.9.1 RTP header extension for audio mixing gain
The format for sending a recommended audio mixing gain using the RTP header extension shall be as follows:
0 1
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| ID | len=0 |audio-mixing-gain|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Audio mixing gain using One-Byte Header Format
The 4-bit ID is the local identifier of this element. The 4-bit length is the number, minus one, of data bytes of this header extension element following the one-byte header. The URI for declaring the audio mixing gain header extension in a Session Description Protocol (SDP) extmap attribute [95] and mapping it to a local identifier is:
urn:3gpp:audio-mixing-gain
The audio mixing gain is expressed in dB as a signed integer in the range "-127" to "0" (hence the numerical values directly represent the gain in dB). A value of “-128” indicates muting the channel. The meaning of positive values other than 0 is undefined and shall be ignored if received.
An ITT4RT-Tx client may repeat the header extension over multiple RTP packets to improve the likelihood of successful transmission as described in [RFC 8285]. The number of header extension transmissions (for the same recommended mixing gain) should therefore depend on the probability of delivery.
