FMOD API

Audio mods that use FMOD normally each start their own engine, which can clash when several are installed. This library provides a single centralized FMOD instance that other mods can share, so multiple audio mods can work together without conflicts and without wasting memory on duplicate engines. Its cleanup routines release resources when they are no longer needed, which guards against memory leaks and resource exhaustion.

The library tracks the player's position and feeds it to the spatial audio system, so sounds placed in the world are heard from the correct direction and distance. Volume follows Minecraft's own audio settings, and FMOD audio pauses while the pause or options menus are open. Because the library is client-side only, only the client needs it, and a server can run without it. Files are published for NeoForge 1.21.1, and the license is a custom one that is not open source.

Installation is simpler when FMOD Engine is in a standard location, since the library finds it automatically. Where FMOD is installed somewhere else, a custom path can be set in the FMOD API configuration, and the mod scans folders recursively to locate the required DLLs.
