Random sounds, question

[Fyrion]

Hi,

my name is Fyrion and I am a developer and story-teller from the custom story BlackNight which will be released soon.

I have a simple question, that I wanted to ask. You all know the original Amnesia (first level for example) where actually are background noises (wall scrambling, distant roars) which are playing all over the level.

My question is: how do I do this loops, while playing in a level (in the original way the original development team does) to add this gloomy atmosphere to my levels? Like a wall scrambling in the first attempt and some distant roar on the second, while hearing some bats flying away, which affiliates to the next sounds. (always remember, I want the original ones, but I can't find any solutions in the original Amnesia game files hps).

It's a bit annoying for myself, that I can't solve it by myself, because everything in the past I got by myself. But I'm really thankful for every single helpful step that you could give me.

Dismal regards from Black Night
Fyrion
