If the Chairs have still no strong opinion about this, I would request to leave this somewhat editorial issue still open.

It makes more sense that all the relevant information for audio and especially the relevant codecs with their different status be clearly listed in the same "webrtc audio" specification. Especially because we want to address the same interoperability issue.
This will be more consistent and readable.

Then, if more informative text on additional codecs is needed, a separate document can be considered to avoid overloading this webrtc audio document with purely informative text.

Hi,

We chairs was considering inclusion in draft-ietf-webrtc-audio, but we didn't have any strong opinions on this. Based on that several WG participants thinks this should be an independent document, I thus decided that we will start out with an independent document. If the WG feels differently later we can always fold the text into the audio codec and processing requirements document.

I would recommend that the individuals interested in contributing a codec writes an independent submission with focus on the codec considerations around the codec(s) they are interested in. Then we can merge this into a common WG document.

Cheers

Magnus
