this is the first Mod in my life, use at own risk. After install I could use my save-files, but not the quicksave-slot. So save your saves.
What does the mod do ?
It replaces the sound in landing areas and inside stations. I am playing with headphones, and I serously got slightly mad when staying to long in a station because of that humming sound. Looking at the original sound.xml of the game, that bloody sound came out of the lights, shild generators and ventingmachines, sometimes you hear it 3-4 times at once, depending on where you are...
So here is a more decent replacement, and it sounds much more better.
And btw , I changed that crappy Trance barsound into a other. feel free to mod the mod with your favorite loop - just put it in the /sfx/ambient/platform and rename it to interior_bar_music_03.wav - use 16-Bit PCM WAV MONO - I tried leghth up to 1 min, but it propably works with longer loops.
Installation
