Sound Physics Remastered is a client-side mod by henkelmax that adds acoustic simulation to Minecraft Java Edition. Sounds propagate realistically through the environment: voices echo inside caves, footsteps resonate in stone rooms, and audio is absorbed through thick walls. It runs on Fabric, Forge, NeoForge, and Quilt for Minecraft 1.19 through 1.21.
How Sound Physics Remastered Changes Audio
The mod replaces Minecraft's flat audio model with a physics-based simulation. Three effects are applied in real time based on the blocks around you: reverb, attenuation, and occlusion. The system runs a configurable number of raycasts per sound event to model how audio travels through and around your surroundings.
- Reverb: sounds bounce off nearby surfaces and decay based on room size. Open fields sound dry; enclosed stone rooms add a noticeable tail.
- Attenuation: sounds lose volume based on the density of blocks between you and the source. A mob heard through several layers of stone is much quieter than one in open air.
- Occlusion: block materials affect how much sound passes through them. Wood, stone, and glass each have different acoustic properties.
- Debug visualization (optional): render sound bounces and occlusion paths as colored lines in-world using a config toggle, useful for tuning settings.
Installation
Sound Physics Remastered is client-side and does not need to be installed on the server. Drop the jar into your mods folder alongside your loader. No required API or library mod is needed.
- 1.Install Fabric Loader, Forge, or NeoForge for your target Minecraft version.
- 2.Download the correct jar from the mod's Modrinth page. Fabric and Forge/NeoForge builds are separate files.
- 3.Place the jar in your .minecraft/mods folder.
- 4.Launch the game. The mod is active immediately with no additional setup.
Optional Integrations
Sound Physics Remastered works alongside Sodium, Lithium, and other Fabric performance mods without conflicts. Its changes are purely audio-side and do not touch rendering or world generation. Three optional companion mods expand what you can configure.
- Cloth Config API: enables an in-game configuration screen for adjusting reverb strength, occlusion factors, and per-block reflectivity.
- Mod Menu (Fabric): surfaces the Sound Physics Remastered config entry in the Mod Menu list.
- Simple Voice Chat: integrates proximity voice chat audio with the same reverb and attenuation pipeline, so player voices sound muffled through walls and echo in caves.
Questions about this entry.
How do I install Sound Physics Remastered?
Download the correct jar from Modrinth for your loader and Minecraft version, place it in the mods folder, and launch. No required library mods are needed. The mod works immediately with default settings, though optional Cloth Config allows fine-tuning reverb and occlusion values in-game.
Does Sound Physics Remastered work with Sodium or Iris Shaders?
Yes. Sound Physics Remastered is audio-only and does not interact with rendering systems. You can pair it with Sodium, Iris, or any shader pack without compatibility issues. It also works alongside other Fabric performance mods.
Does Sound Physics Remastered need to be installed on the server?
No. The mod runs entirely client-side. Your server does not need it installed. Other players on the same server each install it independently on their own client if they want the audio effects.
Which Minecraft versions does Sound Physics Remastered support?
Sound Physics Remastered supports Minecraft 1.19 through 1.21 across Fabric, Forge, NeoForge, and Quilt. Check the Modrinth releases page for per-loader availability on specific patch versions within that range.
Does Sound Physics Remastered affect game performance?
The mod processes audio in real time but includes substantial performance improvements over the original Sound Physics project. For most systems the overhead is minimal. If you notice audio lag, reducing the raytracing count in the Cloth Config screen can help.
