I agree there's been discussion about existing codecs, and most of it has been helpful and constructive.
But until the detailed requirements have been determined, I don't think it is very fruitful to continue it.
IMHO we'll need those details to be more precisely stated (and agreed to) in order to take this to the next level. It'd be most efficient to do the formal assessment only once.

and surely before. We have plenty of representatives from other SDOs
present in the group, so my question is, if such codecs exist, then surely
they should be put up, if not as contenders, then as baseline measures of
best practice in some matter or another. Why hasn't that happened?
With the exception of a few "G.711 should be enough for anyone" jokes,
I haven't seen anyone present a "this can already do what you want" codec
that the group hasn't responded with "we can (already) do better than that".
If there are other codecs that we should have to measure up against, then
indeed I'd warmly welcome other SDOs to make their best suggestions soon,
for consideration during the next stage of work. Anything you think puts
one of the existing candidates to shame in some aspect or another, would
certainly be a valuable and practical measuring stick we can use.
I'm pretty sure a lot of people have already done many of these measurements
for themselves. We just need to whittle that down to the ones that give us
useful bars to raise. Which ones are we missing still?
Cheers,
Ron
