Sound Physics is a mod that overhauls Minecraft's sound engine to simulate reverberation, sound occlusion/absorption, and physically based sound attenuation. The sound simulation provides interesting aural cues; you'll be able to tell whether a mob can be directly seen and whether it's just around the corner or in a closed-off area with your eyes closed. Exploring caves is much more immersive, and reverberation provides a sense of scale to grand structures or large underground ravines.
Shame cause I have resource packs that replace C418's beloved records with music playlists, album covers and all. But hey, a mono conversion would be worth it. Not many think of things like this. Keep up the good work Cody!
is there any way to get this mod without forge that doesn't also preclude using optifine? i need optifine but forge breaks my world by making chests not openable under half slabs. but i use optifine because the built in shader support is way better than anything else. any ideas? anyone know of a mod that makes chests ignore blocks on top?
