Bit cruncher
by Ghouldubs
Bit cruncher reduces the bit depth and sample rate of Minecraft's in-game audio, giving sounds a gritty retro character when the mod is installed on a client.
What it does
Every sound that passes through the mod is run through a bitcrusher, which lowers the resolution of the waveform. Sound effects from mobs, blocks, ambience, the interface and music all receive the effect, so the whole game takes on a lo-fi tone. Players can choose a Game Boy preset, a chunky 4-bit handheld style, an NES sample channel character or a raw 8-bit 11 kHz sound card style.
Bit depth, sample rate, aliasing, drive, and low and high cut can be set by the player to shape the result. Quiet sounds keep their fading tails crunchy rather than dissolving into hiss, and the mod can be set to follow the sound style of each source. The effect is client-side only, so players install it alone and servers do not need it. Bit cruncher is released under the MIT License, but it is not open source. Files exist for 1.21.1, 26.1.2 and 26.2, and the latest Fabric file is 2.0 for 26.2, published 2026-10-12.
