Signaling for immersive audio rendering

A system for enabling immersive audio rendering, comprising:

• a memory;
• and
• a processor configured to execute instructions stored in the memory to:
• receive input audio generated in a recording environment;
• generate one or more bitstreams based on the input audio, the one or more bitstreams including i) audio content generated by a content creation tool for input to a type of audio renderer, selected from a plurality of types of audio renderers, ii) a selected sub-type of the type of audio renderer, and iii) a version of the selected sub-type of audio renderer, wherein the one or more bitstreams indicate a start channel index and an end channel index in which the selected type, sub-type, and version are effective;
• and
• transmit the one or more bitstreams to enable a player to utilize an audio renderer, for playback of the audio content in a playback environment, of the selected sub-type and the version signaled in the one or more bitstreams.
