It happened before my time, but I rather suspect that the answer is that 3GPP specifications have a set of required and recommended audio codecs (AMR, AMR wideband, AAC, AMR WB+) and that there was neither need nor desire to add to the terminal load a new codec. Someone would need to come to 3GPP and convince the membership it's in their commercial interests to require (and thus implement) a new audio codec over and above the current required and recommended set, and I doubt that anyone even tried. -- David Singer Apple Computer/QuickTime
