Hi Damien, To be honest I don't put to much stock in sound encryption schemes. For one reason it adds allot of overhead to your game project to secure the sounds from hackers, which it will do some, but usually since sound encryption schemes are based on similar principles a skilled hacker can crack them pretty easy. One reason I am currently not using encryption is for the fact in a game like Monty where sounds are constantly unloaded and reloaded based on the players placement in the temple it would add considerable overhead and CPU power to decrypt, load, play, and unload encrypted sounds. Most of the game engines out there use a proprietary sound pack file such as pak1, pack2, pack3, Goo, Gob, Meg, etc and all of them have been cracked. Dragon Unpacker can crack a huge number of sound packing schemes, and unless you are better than the pro companies I doubt you can come up with a packing scheme which is totally unhackable. However, if your goal is not to secure sounds from theft, but secure your game from alterations that is a different story. You can do things to supply specific file lengths, formats, etc which allow you to control which files are loaded and reject alterations that are undesired, and encryption is one way of doing this. Cheers.
