Setting up the audio propagation in the Thief level editor is super tedious but it’s hard to argue with the results. You draw “Room brushes” (basically boxes) to encompass space and sound will propagate across where they intersect with each other. An Environmental audio setting is applied to a room brush and will be applied to all the audio heard by the player when inside the room brush.
