Hi Bob,
I suspect you are talking about licensing HE AAC codec (also known as
aacPlus or SBR) from Coding Technologies?

I haven't licensed any source from CT, but I have some good experience with
their HE AAC source available as part of 3GPP (their commercial codec
shouldn't be much different). I was very satisfied with it, very
professionaly done, and, what was the most important for me, their encoder
gave excelent audio quality. I think it's by far the best HE codec developed
so far (this isn't a surprise since CT invented this technology). I don't
see why one would need any significant development.

Also, I have some info that their source is pretty cheap (cheaper than
expected), as their interest is to spread the technology and make money on
patents (Dolby-like). This is just an assumption.

Try www.hydrogenaudio.org forum for more info, many codec developers hang
out there.
