MAtmos is a sound atmosphere generator built for Minecraft 1.12 and 1.7.10. Originally created by Hurricaaane, it is now maintained by the community.

Whenever you join a multiplayer server or single-player world, MAtmos will search your surroundings and generates a soundscape of natural noises to match, filling out that perpetual silence of Minecraft.


What's new?

  • New system for detecting when the player is outdoors, indoors, or deep indoors
  • A new soundpack making use of the new features: Matmos 2020 "Zen"
  • Update checking for sound packs which support it
  • Versions are now built for Forge
  • Many bug fixes and performance improvements


Featured soundpacks
MAtmos lets you create your own soundscapes using special resource packs called soundpacks. Some of the ones that have been created are:


MAtmos 2020 "Zen"

The flagship soundpack, featuring seamless loops and indoors/outdoors variations for ambiences. It aims to add high quality sounds that enhance the atmosphere without feeling out of place. (MAtmos 34 or higher required.)

By default, MAtmos does not include any sounds. To get started, move the soundpacks you want to your resource packs folder an enable them.

Pressing F7 opens the MAtmos settings menu which can be used to adjust the volume levels of the individual expansions that make up soundpacks. You can even combine different expansions from different soundpacks! Customize your experience to exactly the way you like it.


Suggested companion mods

Dynamic Surroundings for better footstep sounds. (Yes, it's compatible.) Disable its biome sounds in the config to only get the footsteps.

Sound Filters / Sound Physics (1.7.10 build here) for reverb and muffling of sounds behind walls.



If adding MAtmos on 1.12.2 causes the game to crash upon startup, it's probably because you're using other, outdated mods that use version 0.7 of the Mixin library, while this mod uses version 0.8. This problem commonly occurs with old modpacks. There are 2 ways to resolve this:

a) Update the other mods of the modpack

b) Use the versions of MAtmos ending in -mixin0.7.jar which are provided for compatibility.
