Does anyone know of a quick and easy way of converting 5.1 AAC to 5.1 AC3 without destroying the channel structure? I already know of several ways of doing this but all of them involve a lengthy process using multiple apps or somehow degradates the channel information.

If anyone still wants to know, VLC can do that

I wanted to update this.

I found a guide over at the doom9 forum that worked for me in regards to 5.1 AAC to 5.1 AC-3

Here is a direct link: CLICK HERE

I used the GraphEdit method described in that post but I didn't realize that if you simply scroll up one post that there is yet another method using a program called aacDecDrop along with the oldie but goodie program BeSweet. This method makes more sense to me but I haven't tried it yet. However I can confirm that the GraphEdit method did work for me although to date I've only had one occasion to try this type of audio conversion.

Cheers !!!

P.S.
The AAC audio file was in a MKV file and when I demuxed it and tried to load it into GraphEdit I was getting an error however when I opened the MKV file into GraphEdit it worked. Might have been the way I demuxed the AAC (seems like a sound guess to me) but I didn't try exploring other demuxing options since I got it to work by loading the MKV file. I just wanted to point out this "pitfall" for others that might be trying the same method at some point.
