Hi Fishman,
long time no see, good to hear from you after a long time...
After a stroke last year I am no longer the smart person I used to be, but I try to find my way back step by step. And your request for the Fraunhofer AAC encoder for dmMediaConverter sounds pamiliar to me. This AAC codec is way better than the standard AAC encoder, it just cannot be included in standard distributions due to the incompatible Fraunhofer license.
The latest version with complete documentation is here:

And Reino´s FFmpeg versions are here:

Good luck and cheers
