How do i make sounds for my CS?

Record it with any program you wish, such as Audacity. Then you're going to have to find a program which can convert your soundfiles into .ogg format, the .snt files are basicly settings for the sound.
If you open one of the snt files with notepad there are things like volume and such which can be corrected in there.

To create a new sound in the most simple way would be to record and convert, put your new .ogg file into a folder within the amnesia directory and then copy paste a .snt file from the original sounds and then rename the .snt file to whatever your sound is called and change the settings of it in notepad accordingly.

I hope this helped to some degree.
