[opus] Are the ITU's stretched-to-wideband codecs being used?
Hi, The ITU has been churning out a series of codecs which stretch older codecs to support wideband or super wideband and stereo. Does anyone know of these things being used in the real world? They push the idea of these things offering high compatibility, as the narrowband bitstream is embedded in the wideband stream. However, I'm skeptical this offers any real world advantage. Regards, Steve

I could be wrong, but I don't think these codecs are being in used very much. I also suspect most of the uses are in places we don't see, like inside a carrier's network. In any case, I never found these new extensions that interesting. Embedded coding itself has some advantages, but embedding an old codec pretty much cripples the result IMO.
