Euphonium
With Euphonium installed, the ambient sound of a player's surroundings changes with the biome, structures and environment the player stands in.
What it does
Euphonium plays ambient sounds that follow the biome, nearby structures and environment around the player, adding to vanilla soundscapes. It descends from a rewrite of the Charmonium project, carried forward with new build scripts and a TOML configuration instead of the original API.
Euphonium runs on the client only, so servers do not need it and players can join without installing it. It requires Fabric API, and it works with Fabric, Forge, NeoForge and Quilt. Builds cover 1.18.2 – 1.21.1 across eight release versions, and the code is released under the GNU Lesser General Public License v3.0 or later, so it is open source. Connector and FFAPI are needed on Forge and NeoForge, and McQoy is optional.
Key features
Biome and structure ambience
Ambient sounds are tied to the biome, structures and environment the player is in, so the sound changes as the surroundings do.
Ambience volume slider
A volume multiplier for world ambience is adjusted through the Ambient Sounds slider to set the overall mix.
Per-type ambience toggles
Each type of ambience can be switched on or off separately, so a player can keep only the sounds they want.
Cave darkness tweaks
Ambience in caves and dark areas has its own adjustments, changing how underground sound feels.

Use cases
Immersive vanilla play
Players who want more atmosphere in vanilla worlds can use the mod to add biome-based sound without changing any gameplay.
Modpack foley
Modpack authors can pair Euphonium with a footstep sound mod to add more footstep detail to an atmospheric pack.
Who it’s for: Players who want biome and structure-based ambient sound in vanilla-style worlds, and modpack authors building atmospheric packs on Fabric, Forge, NeoForge or Quilt.
How it compares
Charmonium has its own biome and structure ambience with Fabric and Quilt files for 1.17 – 1.21 and an MIT License, so it is open source. Effective covers the same loaders as Charmonium for 1.18 – 1.21.1, but it is client-side only under All rights reserved and is not open source. MAmbience is a Fabric mod for 1.19.3 – 1.21.1 that can run on a client or a server, and it is open source under the Apache License 2.0.

What the author says
Requires Connector and FFAPI on (neo)forge. Charmonium (and therefore Euphonium) adds biome, structure, and environment-specific ambient sound to the game.
