Enhanced AAC+ 3GPP reference implementation

Hi,

what do you think is the quality of 3GPP's HE-AAC +SBR/PS reference implementation? As it is completely available in source code, I consider there could be heavy restrictions considering quality of SBR and PS implementation.

Regards, GW

At least the SBR/PS part is crippled. I didn't look at the pure AAC part enough to tell.

The crippiling isn't actually so bad, though...

Willie,
As I was told by the people from Coding Technologies, 3GPP HE+PS AAC encoder (they wrote) is "optimized for quality" since it is the 3G's NORMATIVE implementation. It is very well maintained and should be bug-free (contrary to ISO code). However, it is "NOT usable for anything but 3G compliant products", so you will have to honor their rights...
