Sound Physics Mod FAQ

Walk into a cave or a large enclosed room and listen for reverb and echo that vanilla Minecraft doesn't have. If sounds fade naturally around corners and get muffled through walls, the mod is active. If everything sounds flat and identical to vanilla, check that your audio output isn't set to mono-downmix or that another sound mod isn't overriding it.

Those sounds are stereo files, and Sound Physics Mod can only spatialize mono audio. Stereo sounds bypass the mod's attenuation and panning entirely, so they always play at full volume. Convert the offending sound files to mono in an audio editor to fix it.

Export every custom sound as a mono file, not stereo. Open the file in a free editor like Audacity, split the stereo track to mono, and re-export. Once it's mono, the mod will apply occlusion, reverb, and distance attenuation correctly.

The sound simulation does real-time raycasting for occlusion and reverb, which is CPU-heavy. Lower the reverb quality, reduce the number of simulated sound sources, or disable occlusion in the config if performance drops. Testing in a busy area with many mobs will show the worst-case impact.

It can conflict with mods that also rewrite the sound engine, like Dynamic Surroundings or certain audio overhaul mods. If sounds behave strangely, disable the overlapping features in one of the mods or test them separately. Mods that only add new sound files usually coexist fine as long as those files are mono.

Listen for the direction and muffling of the sound: a mob around a corner will sound slightly occluded and off to one side, while one in the same open room will be clear and centered. Reverb tells you if it's in a large cavern versus a tight tunnel. Combine panning, volume falloff, and reverb tail to triangulate.

Reverb scales with the size and enclosure of the space, so a large open room will always echo more than a small one. Tune the reverb strength and decay in the config to match your preference. If it's overwhelming, lower the reverb amount rather than disabling it entirely.

Yes, the simulation runs in any dimension, but the acoustics depend on the geometry around you. Open areas like the Nether's lava lakes will have little reverb, while enclosed fortresses or End cities will echo. The mod doesn't add dimension-specific reverb presets by default.

Occlusion is working as intended: walls absorb and muffle sound based on their material and thickness. If it feels too aggressive, reduce the occlusion strength in the config. Some blocks absorb more than others, so a dirt wall will muffle less than stone.

Check that your game's audio output is set to stereo or surround, not mono, and that no other mod is forcing mono downmix. Then visit a cave or large structure to confirm reverb and occlusion are active. Adjust reverb and occlusion strength in the config only if the defaults feel wrong for your setup.

Reverb is generated automatically from the geometry around you, so you just need to be in an enclosed space with hard surfaces like stone. Digging out or standing in a large open cavern or ravine gives the strongest sense of scale.

Listen for the muffling and absorption: a mob behind solid blocks sounds duller and quieter than one with a clear line of sight. Sounds coming from around a corner arrive slightly attenuated and without the direct high-frequency clarity of a visible source.

No, this mod is built for the Java Edition sound engine and relies on Java-specific audio hooks. Bedrock and Pocket Edition have a different audio system, so there is no equivalent version of this mod for them.

Occlusion and absorption are reducing volume for sounds that pass through blocks, which is intended behavior. If it feels excessive, tune the mod's occlusion and attenuation settings rather than turning your master volume up.

Export every custom sound as a mono file, since stereo files bypass the spatial simulation entirely. Check each file in an audio editor and downmix to a single channel before packing it into your resource pack.

The simulation runs on the audio thread and adds some CPU cost from raycasting for occlusion, which is usually minor but can be noticeable in huge builds or with many simultaneous sounds. Lowering the mod's quality or update settings reduces the load if you see stutter.

It generally coexists with shaders and most audio mods, but other mods that replace the sound engine or add their own reverb can conflict or double up effects. If audio sounds wrong, disable the other sound-altering mod and test again.

Adjust the reverb and occlusion settings so large halls feel expansive without drowning out nearby sounds, and test by walking from a small room into a large one. Matching the reverb strength to the actual size of your build keeps the sense of scale believable.
