Sound Culling

Sound Culling

Sound Culling is a client-side Minecraft mod that reduces repetitive sounds in
busy areas such as farms, spawner rooms and machinery. It can lower a sound's
volume or prevent it from starting when nearby sound activity exceeds the
configured limits.

The mod tracks recent sound events by location and source. Each decision can
consider repetition, regional activity, sound category, distance, direction and
the current event rate. A single noisy source has a limited contribution to the
shared regional count, while repeated sounds from that source are still detected.

Sound Culling only changes client audio. It does not alter entities, blocks,
gameplay or server behaviour, and it does not need to be installed on the server.

Features

• Rejects excessive sounds before they start an audio channel.
• Dampens sounds when full rejection is unnecessary.
• Adjusts limits as the overall sound event rate rises.
• Tracks nearby cells to avoid sharp changes at region boundaries.
• Limits the influence of one source on the regional sound budget.
• Re-evaluates looping and tickable sounds with gradual volume changes.
• Gives player feedback sounds additional protection during ordinary culling.
• Supports exact sound IDs, wildcard patterns and full mod namespaces.
• Shows recent sounds, event counts and session statistics in-game.
• Includes Balanced, Performance, Aggressive and Custom presets.
• Allows playback to continue when sound evaluation encounters a compatible
  runtime error.

Music and relative sounds, including interface audio, are excluded. Sounds that
Minecraft already considers outside their audible range are not added to the
tracker.

Configuration

Install Mod Menu to open the four-page settings screen:

• Overview contains the main toggle, presets and session statistics.
• Performance contains adaptive thresholds and category limits.
• Live Sounds lists recent sound IDs and provides rule actions.
• Advanced contains spatial tracking, priority and logging options.

The screen does not pause a single-player world, so sound statistics continue to
update while it is open. Use Save & Close to apply changes. Cancel
discards pending settings edits.

Settings are stored in:

config/soundculling.json

Older configuration files are migrated where possible. Invalid numeric values
are restricted to supported ranges. If the file cannot be loaded, the mod uses
and saves its default settings.

Presets

Preset	Purpose
Balanced	A starting point for ordinary play.
Performance	Lower limits and earlier adaptive pressure for busy areas.
Aggressive	Tighter limits for sustained sound spam.
Custom	Used after individual limits are changed.

Presets adjust category limits, the regional limit and adaptive thresholds.
They do not remove custom sound rules.

Sound rules

Rules can protect a sound, raise or lower its priority, or prevent it from
starting. Select a sound on the Live Sounds page to create a rule without editing
the JSON file. Protect Mod creates a namespace-wide protection rule.

Available rule actions:

Action	Effect
NEVER_CULL	Excludes the matching sound from Sound Culling decisions.
CRITICAL	Applies the highest priority multiplier.
HIGH	Raises priority under load.
NORMAL	Uses the normal priority calculation.
AGGRESSIVE	Lowers priority.
ALWAYS_CULL	Rejects new starts and fades tracked loops toward zero.

Patterns are case-insensitive and support * as a wildcard:

minecraft:block.piston.*
bettercombat:*
presencefootsteps:*

When several rules match, the last matching rule takes precedence. Exact IDs in
the legacy whitelistedSounds list take precedence over rules, including
ALWAYS_CULL.

Commands

Sound Culling provides client-side commands that do not require server operator
permissions:

/soundculling
/soundculling toggle
/soundculling preset balanced
/soundculling preset performance
/soundculling preset aggressive
/soundculling limit <1-50>
/soundculling total <1-100>
/soundculling reset

The base command shows the current preset, event rate, adaptive pressure and
session counts. Setting commands apply and save immediately. The reset command
clears session statistics and recent sound history; it does not clear rolling
activity used by current culling decisions.

Installation

1. Install Fabric Loader and Fabric API for your Minecraft version.
2. Download the Sound Culling file listed for that Minecraft version.
3. Place the JAR in the instance's mods folder.
4. Install Mod Menu if you want access to the settings screen from the Mods menu.

Minecraft version groups use separate builds, even when their JAR names are
similar. Check the supported version shown on the individual download file.

Sound Culling 2.0 is available for Fabric. Older files for Fabric, Forge and
NeoForge may use the earlier engine and may not include the Live Sounds page,
adaptive pressure, wildcard rules or persistent loop management.

Modpacks

Sound Culling may be included in modpacks. It is client-side and distributed
under the MIT License. A pack can use presets and rules to tune behaviour for its
sound-producing mods. If a mod uses an unusual playback path, test its one-shot
and looping sounds before publishing the pack configuration.

Reporting problems

Report issues at GitHub and
include:

• Minecraft, loader, Fabric API and Sound Culling versions.
• The downloaded file name.
• Steps to reproduce the problem.
• Other mods that change sound playback.
• logs/latest.log and the crash report, if one exists.

For missing audio, also include the sound ID if known, any matching rules and
whether the sound is a one-shot or a persistent loop.
