Command line interface for Winamp AAC encoder

I would like to run the Winamp 5.52 AACplus encoder from the command line.

I found a command line executable that works with Winamp 5.3 (mentioned in this earlier thread). I tried it with the enc_aacplus.dll from Winamp 5.52 and it seems to work, but I'd like to be more confident that this is OK and that all of the parameters are getting passed properly. Unfortunately, I can't figure out who compiled the executable or how it was put together. Does anyone know where I can find more information about it?

Also, does anyone know of any other command line executables for the Winamp AACplus encoder, perhaps ones that are more recent or better documented?

I suppose I could try to write a command line exectuable myself, but I wasn't able to find an API for the Winamp AACplus encoder. Does anyone know if it's out there? I see that MediaCoder manages to call the Winamp DLL, but it seems like a lot of work to reverse-engineer MediaCoder's source code to figure out the API.

Thanks!

I guess it would be easier to just use Nero AAC encoder? AACplus is just a trademark - It's tech term is HE-AACv2 which at least Nero also supports.
Can't wait for a HD-AAC encoder :P

I have found three implementations of HE-AACv2 (a.k.a EAAC+ a.k.a AACplus v2):
From what I can tell, they are not identical, and I am interested in comparing them.

Does anyone know of any other implementations out there?
