AudioEnginePlus

The mod reuses existing sound instances rather than allocating new native memory for each sound, which limits the Java garbage collection spikes that sound playback can cause. Identical sounds that start together in the same spot are merged, so fewer voices compete for the CPU in busy areas. Audio decoding runs on a separate thread, and decoded data is cached so that many sounds starting at once do not stutter.

Sound quality and processing frequency are scaled according to the player's distance from each source. Nearby sounds keep full fidelity, while distant ones are processed less often. Heavy audio calculations are moved away from the main game thread. The mod is client-side only, so only the player's client needs it and servers run without it. A configuration screen built on ModMenu and Cloth Config exposes the engine's settings. Built-in compatibility is included for Sound Physics Remastered, so both can run together.

The code is released under the GNU Lesser General Public License v3.0 or later. Files are published for Fabric only, for 1.21 – 1.21.11, with 4.0.0-alpha for 1.21.11 as the latest build.
