A backfork of Charmonium.
Requires Connector and FFAPI on (neo)forge.
Features
Charmonium (and therefore Euphonium) adds biome, structure, and environment-specific ambient sound to the game.
By default, volume can be tweaked through the "Ambient Sounds" slider.
Configuration
Euphonium can be configured via config/euphonium.toml, including:
- Sound channel
- Volume multiplier for world ambience
- Toggles for each type of ambience
- Tweaks for cave darkness ambience
Design
This is a fork and backport of Charmonium 6.0 - an excellent rewrite of the mod by svenhjol!
Charmonium 6.0 can't be reliably built from source. It's API, Charmony, is also not source-visible.
To remedy this, Euphonium has all new buildscripts and forgoes Charmony, using Kaleido for a toml config.
We recommend combining this with Presence Footsteps for further foley depth.
Afterword
All mods are built on the work of many others.
