The level.snd_static file in Shadow of Chernobyl controls which sound sources play in certain parts of levels. They can only play one sound, but it can be of any length. They are used to play sounds like a desk fan or electrical sparks. Even a radio on a table.
Download the sse.exe utility here: http://stalkerin.gameru.net/downloads/stutils/sse_01.zip.
Then run this command to decompile the level.snd_static file.
>sse -d level.snd_static |
Then make your edits. This example adds a radio in one of the houses in the Stalker village.
[6] name=scripts\magnitofon\magnitofon_2 position=-192.59, -19.12, -137.581 volume=0.5 freq=1 active_time=0, 0 play_time=0, 0 pause_time=0, 0 |
Then use this command to recompile a new file.
>sse -c level.snd_static.ltx |
This works very well and does not require Activeperl, as the Perl script does not seem to work anymore. This is a great way to add more sounds to a map.
