Cave Ambiance Sounds Needed

- Reverb when walking, breaking blocks, receiving xp, or any other action underground. The decay, reflections, diffusion of the reverb could vary; decreasing and increasing depending on the size of the cavern the player is in.

- Quiet and low rumble fading in when the player gets close to the bottom of the world. This could reinforce the idea that the void is near (even if it can't be accessed)

- Filter on sounds behind walls: It often happens that I locate caves through mobs screams' when stripmining. A filter for a muffling effect to those behind walls noises could make it more realistic.
