Hi,

We would like to propose updating the Opus codec (RFC 6716) to take 
advantage of recent advances in speech and audio coding, including uses 
of deep learning. The intent is to remain fully compatible (forward and 
backward) with the original specifications. More specifically, we would 
like to propose the following goals:

1) Improved packet loss robustness through ultra low bitrate in-band 
redundancy
2) Improved low-bitrate speech (SILK) quality with and without side 
information
3) Improved low-bitrate music (CELT) quality with and without side 
information

The compatibility-preserving extension mechanism we are proposing is 
detailed in this draft: 
https://datatracker.ietf.org/doc/draft-valin-opus-extension/

We also have an initial proposal for goal 1) above in this draft: 
https://datatracker.ietf.org/doc/draft-valin-opus-dred/

We would like to request a slot on the agenda to present these drafts, 
seek feedback, and discuss the best ways of moving this work forward.

Cheers,

     Jean-Marc
