Brute Force was tried and failed. The actual encryption algorithm was found to be weak so figuring out encryption key was easy. A singular .exe program was compiled for the specific discs of audio as each set probably has their own separate encryption key so it's a 1 shot deal.

The lucky part ..... the encryption didn't change throughout the soundtrack, other wise I'd only have a piece of the puzzle.

At this point, I now have PCM audio from the encrypted .aue files. This has been a cool journey but it's not over. We obviously are going to do other testing to see what can be done, if anything, to create something more universal for this subject matter.

Thanks to my partner Maxim in this. He was nothing but cordial, understanding, helpful, and 100% gracious.

The cool thing about this .exe program is that I can use it to convert the .aud files straight to 5 channel PCM so I'm going through the discs I do have and redoing the reels. They will still have to go through some processing but I'd think this is a better way to go to keep the quality.

Interesting stuff! I read somewhere that the encryption would let you play the first 2 minutes or so with the in_aptx plugin (as you would an AUD) and then you would get garbled noise afterwards. You say the encryption has been cracked with a custom executable, so was achieved without the use of the 6D and ripped straight to PCM? Are these PCM files in the format of a single 5-channel PCM file for each reel? If so, are the channels in the correct places?

Sorry for all the questions, but this is all very impressive and exciting! Very well done to you and your partner!
