Audio Improvements

Overview Audio Improvements is a client-side mod that enhances Minecraft's sound system without requiring server installation. So it runs on Fabric and NeoForge across Minecraft versions 1.21.11, 1.21.1, 1.20.1, 26.2, and 26.1.x. On Fabric it requires Fabric API and YetAnotherConfigLib (YACL); on NeoForge only YACL is needed. Forge is supported for 1.20.1 but not for the other listed versions. Settings open via Mod Menu on Fabric, the built-in mod list on NeoForge, or the command /audioimprovements. The project is licensed under GNU LGPL v3.0 or later. ## Mono audio and spatial controls The headline feature is per-category mono audio. When enabled for a category, sounds stop panning based on where you look but still get quieter with distance. Categories include jukeboxes, note blocks, weather, blocks, hostile mobs, neutral mobs, players, and ambience. Only jukeboxes and note blocks are mono by default. Speed of sound simulation adds a delay based on source distance. Thunder and explosions default to 100 blocks per second; all other sounds are disabled by default. Doppler effect pitches sounds up or down as the distance between you and the source changes, but it does not work on mono sounds due to engine limits. A stereo spatialization fix converts stereo files used for in-world sounds into mono so the engine can position them correctly instead of playing them directly at the listener; this is off by default. ## Volume and music behavior Logarithmic volume sliders replace the linear vanilla scale so slider position matches human loudness perception. And this is enabled by default and was inspired by the Logarithmic Volume Control mod. Music clash prevention fades out the regular game soundtrack when a jukebox or note block plays nearby. You can toggle each source separately and set custom fade-in and fade-out durations; both are on by default. Music repeat prevention stops the same track from playing twice in a row and is enabled by default. Custom music frequency replaces the vanilla music interval with a configurable random range and can optionally affect the main menu music; it's disabled by default. Music disc distance multiplier scales how far disc audio travels from 50 percent to 300 percent of the vanilla value, or uses a global 100 percent setting. ## Vanilla bug fix For versions before 1.21.9 the mod includes a fix for MC-98200, where certain sound category sliders stopped affecting volume above 25 percent - music discs would already be at full volume at the quarter mark.
