This document defines an extension to the Opus audio codec to encapsulate coded ambisonics using the Ogg format. It also contains updates to RFC 7845 to reflect necessary changes in the description of channel mapping families.
Working Group Summary
There were no particularly controversial aspects of this draft, and consensus on all decisions was generally easy to reach.
The format has been implemented in the open-source libopus library (using an experimental mapping family identifier), with support included in the opus-tools package. Several significant vendors have indicated a plan to implement the specification, including Gooogle, Mozilla, and the open source VideoLAN and FFmpeg projects. Mark Harris performed a particularly thorough review, and motivated many of the necessary updates to RFC 7845. In addition, the updates to the "Opus Channel Mapping Families" IANA registry were reviewed by the original authors of RFC 7845 (which created that registry).
