AcousticKey

Every keystroke, now with a thock.

A client-side Fabric mod that plays mechanical keyboard and mouse sounds as you type and click. No server install, no background app — just drop it in mods/ and your membrane keyboard starts sounding like a custom build.

Why AcousticKey?

Most "keyboard sound" setups mean running a separate desktop app that fights Minecraft for your audio device. AcousticKey lives inside the game instead: it hooks key and mouse input directly and plays sounds through the game's own audio engine. That gives it three properties a background app can't match:

	AcousticKey	External app
Setup	One jar in mods/	Install + configure + autostart
Latency	Plays on the input event itself	OS-level hook, then audio routing
Per-game control	Mute key, volumes, pack picker in-game	Alt-tab out to change anything

---

Controls

Both hotkeys are standard Minecraft keybinds — rebind them like anything else under Options → Controls → AcousticKey.

Action	Default	Notes
Open settings	K	Works from title, world, or inventory
Toggle mute	M	Instant, no menu needed

The settings screen footer always shows your current binds (e.g. J = GUI │ N = Mute), so it never lies after a rebind.

Settings screen

Press K (or your bind) anywhere:

• Pack lists — click to switch, applies on the next keypress. Scrollable.
• Volume — separate sliders for keyboard and mouse, 0–100.
• Mute — hard mute without touching your volumes.
• Key-Up — extra sound on key release. Off by default; it gets chatty.
• Mouse — kill click sounds without affecting keys.
• Random — slight pitch variation so repeated keys don't sound robotic.
• Refresh — rescan the soundpacks folder after adding a pack.
• Open Folder — opens the soundpacks folder in your file manager.

Everything saves to .minecraft/config/acoustickey.json automatically:

{
  "keyboardPackId": "cherrymx-blue-pbt",
  "mousePackId": "default-mouse",
  "keyboardVolume": 80,
  "mouseVolume": 80,
  "muted": false,
  "keyUpEnabled": false,
  "mouseSoundsEnabled": true,
  "randomSoundsEnabled": false
}

Soundpacks

Included

This mod ships with 4 packs from Mechvibes:

• Cherry MX Blue — clicky (cherrymx-blue-pbt)
• Cherry MX Brown — tactile (cherrymx-brown-pbt)
• Cherry MX Red — linear (cherrymx-red-pbt)
• EG Oreo — creamy (eg-oreo)

Plus default-keyboard / default-mouse built-in configs. If no pack is selected or a pack's files are missing, nothing plays — never an error sound.

Add your own

1. Press K → Open Folder (or open .minecraft/config/acoustickey/soundpacks/)
2. Drop in a folder with a MechVibes++-style config.json plus its audio files
3. Hit Refresh — it appears in the list

Format matters: only ogg and wav play. m4a/mp3 files are skipped silently. Convert with Audacity (Export → Ogg) or ffmpeg:

ffmpeg -i sound.m4a -c:a libvorbis sound.ogg

then rename the extension in the pack's config.json to match.

<details> <summary>Where packs live</summary>

Two folders — keyboard packs and mouse packs are kept separate:

.minecraft/
└─ config/
   ├─ acoustickey.json
   └─ acoustickey/
      ├─ soundpacks/      <- keyboard packs
      │  ├─ cherrymx-blue-pbt/
      │  ├─ eg-oreo/
      │  └─ my-pack/
      └─ mousepacks/       <- mouse packs
         ├─ logi-g502/
         └─ my-mouse/

Installation

Requires: Fabric Loader ≥ 0.19.3 · Java 21 · Fabric API

1. Install Fabric Loader for your version.
2. Put fabric-api-*.jar in mods/ (skip if present).
3. Put the right acoustickey-*.jar in mods/:

File	Minecraft
acoustickey-*-mc1.21-1.21.8.jar	1.21 – 1.21.8
acoustickey-*-mc1.21.9-1.21.11.jar	1.21.9 – 1.21.11

1. Launch → Options → Controls → AcousticKey → set your keys → press K.

Singleplayer and servers both fine — the server never needs the mod.

FAQ

<details> <summary>Can I change K / M?</summary>

Yes — Esc → Options → Controls → AcousticKey, click the entry, press the new key. The settings footer updates immediately, no restart.

</details>

<details> <summary>No sound at all?</summary>

Check M (mute) and both volume sliders first. Then check the pack: open its folder and confirm the audio files are ogg/wav — m4a/mp3 are skipped. Try a bundled pack (cherrymx-blue-pbt) to isolate it.

</details>

<details> <summary>Mouse clicks silent but keys work?</summary>

Two causes: Mouse: OFF in the panel, or the selected mouse pack's files are missing/unsupported. Enable Mouse: ON, or switch to default-mouse.
