Beat Lamp
by HyIsNoob
Beat Lamp is a music visualizer mod that adds concert lighting blocks, lasers, fog and fountains which react to the beat of nearby music.
What it does
The mod adds a set of decoration and technology blocks that respond to music in real time. The Beat Lamp block, a music visualizer with nine reactive modes such as Spectrum, VU Meter, Wave and Matrix, is the core of the set. Other blocks include an ambient LED block that runs continuously without music, an RGB laser projector with up to 16 customizable beams, a Stage Light with moving-head spotlights that sync to tempo, a water stage fountain, a fog generator and a Beat Emitter that converts live beats into redstone power.
Vanilla discs, modded discs, streamed music and resource packs can all drive the lamps, since Beat Lamp does not depend on one source. Its effects are built for recording as well: the mod is compatible with Replay Mod, and offline video export mutes Minecraft audio while lamps receive sound signals during export. The client settings menu, opened with O, lets players adjust the concert options, and the interface is available in English, Vietnamese and Korean.
Beat Lamp is client and server, so the server and every player need the mod. It is released under the MIT License and is open source, and it is published for Fabric, Forge and NeoForge across five release versions, 1.20.1 – 1.21.8.

How it compares
Media Visualizer is client-side only, open source under the MIT License and published for Fabric, Forge and NeoForge across 1.20.1 – 1.21.11, so servers can run without it. Cozy Night Lamps is for Forge and NeoForge only, covers 1.20.1 – 1.21.1, is client and server, and is released under All rights reserved, which means it is not open source.
