EchoVision

Hear the world. See its echoes.

EchoVision is a client-side Fabric mod that turns Minecraft into an acoustic world.

Activate it, and the familiar terrain falls into darkness. Sounds produce expanding, pixelated GLSL waves that briefly illuminate the edges of blocks, surfaces, and nearby entities.

Instead of ordinary vision, you navigate by listening.

Features

• Sound-driven vision — each detected sound produces an expanding wave that reveals nearby geometry.
• Procedural pixelated shaders — crisp voxel-style illumination with short afterimages and no full-screen noise overlay.
• Enhanced hearing — supported Minecraft sounds receive local amplification.
• Fully client-side — no server installation, custom items or operator permissions required.

Commands

/echovision on — Enable acoustic vision.

/echovision off — Return to normal Minecraft vision.

The effect is disabled by default and resets automatically when disconnecting.

Requirements

• Minecraft Java 1.21.1
• Fabric Loader
• Fabric API

Install the mod in your client's mods folder. No server installation is necessary.

Limitations

EchoVision can only use sounds, blocks and entities already available to the Minecraft client. Some complex entity models use simplified outlines. Compatibility with other rendering mods has not been extensively tested.
