Sound Physics Mod (1.21.3, 1.20.1) – Amazing Sound Shaders in Minecraft

Sound Physics Mod (1.21.3, 1.20.1) 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.

Any sound files that are stereo instead of mono will not function properly! If a sound file is stereo, the sound will always play at full volume with no spatial panning no matter where the sound is coming from or how far away it is! If you are making custom sounds, make sure that they’re mono! You can use a free audio editor like Audacity to convert stereo sound files to mono.

You should set the Environment Evaluation Rays in the Mod Options to the highest value that doesn’t produce stuttering when sounds play (which shouldn’t be an issue on moderately capable CPUs). More rays will give a more consistent and accurate sound simulation.

If your Minecraft is running at a low frame rate (below 30 fps), some sound artifacts can occur (a sound randomly having the wrong reverb settings).

Screenshots:

Ray visualisation: A piston sound raycast. All blocks that are queried by raycating have a particle on top. (used structure_void)

64 rays: Hearts = ray hits heard by player

1024 rays: New performance allows to have that

Sound redirection: White (end rod) dot is the new location, at which you hear the sound of the piston enclosed in the bedrock box

New ray visualisation: Rare moment just a bit after the dropper is triggered (in a 30³ barrier box)

Ray hell: Just after the previous one.

Requires:
