Ding (Forge) plays a configurable sound when Minecraft reaches the main menu, a world finishes loading, or resources finish reloading. Its name comes from the sound of picking up an XP orb. Available for Forge and NeoForge on Minecraft 1.9–1.21.5, this mod is client-side only.
For your own rented Minecraft server, install Ding with one click from the panel, keeping in mind that its audible notifications run on the client.
