Immersive communication sessions

Abstract

An Immersive Voice Audio Services (IVAS) encoder (for eg. Metadata Assisted Spatial Audio, MASA, using Real Time Transport Protocol frames, RTP) determines an audio processing mode that is supported by an apparatus, transmits a list (via eg. a Session Description Protocol) comprising the audio processing mode, receives a response indicating a preferred audio processing mode based on the transmitted list, and uses the preferred audio processing immersive audio communication session. Possible audio modes include noise or ambient suppression, speech enhancement, compression, amplification or equalization), and the preferred audio mode may be determined based on negotiated bitrate, offered bitrate, ambient noise, capture device or output device.
