Sounds: Is it possible to mod?

[OhMargott]

I know there are already modders working, but, I just wanted to know if there's any way to mod the sounds myself. Does the kegetys thing still work? I use it to change my backgrounds and stuff but can it be used to access the sound files? If anyone has knowledge about this, please reply, Thank you.

Thank you. Do you know any thread, tutorial etc about how to use this? How to extract/modify COD sounds?
