So I work on a multiplayer game that is set in space. There are essentially two environments for players to be in: inside a sealed space station (where there is air and thus sounds) and outside the station in the vacuum of space (where there is no air and no sound to hear).
For a while now, we've had it so that you cannot hear any of our game's sound effects while floating in a space with no air, and while that might be realistic, it's not very fun when the game is completely silent sans background music.
I'd much rather find some way to dynamically distort the sounds on the fly before they are played so that they seem to be muffled or dampened. I have no sort of background in making sounds or doing much of anything with them and all my searches have amounted to nothing; mostly finding things about sound editing programs.
The project is made in a C based language for game programming that is really obscure called Dream Maker or Byond. I can't seem to find any built-in features that are able to solve this problem for me. Any help would be much appreciated.
