Conductor
Conductor targets sound-related lag in Minecraft, aiming to reduce the choppy audio and micro-stutters that lower-end CPUs and devices can hit during play.
What it does
Minecraft's audio system can stall the game while it waits for sound to play, which shows up as lag and micro-stutters. Conductor is a lightweight Fabric mod that works on that sound processing, with the stated aim of removing these issues so players on weaker hardware can run the game more smoothly. It is client-side only, so a server does not need it and players join without installing anything.
Conductor requires Fabric API and is distributed for Fabric alone, with builds covering 1.21 – 1.21.11 and 1.0.0+1.21.11 as the latest file for 1.21.11. Cloth Config API and Mod Menu are optional. The code is released under the MIT License, but the project is not open source.
Key features
Sound processing fix
Conductor reworks how sound is handled so the audio system no longer slows down the game during playback.
Lower-end device focus
The mod is built around players with lower-end CPUs and devices, where sound-related lag is most noticeable.
Lightweight design
Conductor is described as a lightweight mod that targets a long-standing sound performance problem in Minecraft.
Conflict-aware behavior
The author notes that some sound mods can conflict with it, so players using other audio mods should check for issues.

Use cases
Playing on weaker hardware
Players whose machines drop frames or stutter during sound-heavy moments can use Conductor to address that lag.
Running alongside sound mods
Players who use audio-altering mods such as Sound Physics or Sound Physics Perfected can check compatibility, since the author expects some conflicts.
Who it’s for: Players on Fabric who see stutter or choppy audio on lower-end computers, and who want a client-side fix without changing the server.
How it compares
Sound Reloader is also client-side only and published under the MIT License for 1.21.1 – 1.21.11, but it is not open source. ChatLagFix is client-side only, open source under the MIT License, and built for 1.21.11 only, so it addresses chat rather than sound. MChat Fix and Swidget's Hit Sounds are client-side only, both under All rights reserved and built for 1.21.11.
