What Mootboard is

Mootboard is an open-source soundboard and real-time voice changer for Windows and macOS. It processes microphone audio and sends the result to a virtual microphone selectable in Discord, Zoom, and game chat. Listed effects include pitch shift, reverb, EQ, distortion, chorus, flanger, noise gate, and compressor. Effects can be chained, reordered, adjusted per parameter, and switched independently, with named presets for complete effect chains. The soundboard plays imported WAV, MP3, FLAC, and OGG clips through configurable global hotkeys and mixes them into voice output. The README states end-to-end latency of no more than 15 ms at 48 kHz with a 256-sample buffer. First-time setup installs a virtual audio driver and requires administrator access once. Audio processing runs in a Rust engine with a React interface in a Tauri window. Mootboard is MIT licensed; Linux support, noise suppression, accessibility, and OBS integration remain roadmap items.

Who it suits

It suits people who want configurable voice effects and soundboard clips in Discord, Zoom, or game chat. Supported systems are Windows 10/11 x64 and macOS 12 or later on Intel or Apple Silicon.

What it does well

Includes eight listed real-time effects
Chains, reorders, and independently toggles effects
Imports WAV, MP3, FLAC, and OGG
Saves named effect-chain presets
Processes audio locally in a Rust engine

What to know first

Linux is not currently supported
Driver setup requires administrator access once
No published releases were shown

Limits

Mootboard currently supports Windows and macOS; Linux is planned for a future phase. Noise suppression, accessibility features and OBS integration are also roadmap items.

Getting started

Download Mootboard for Windows 10/11 x64 or macOS 12+
Install the virtual audio driver with administrator access once
Open the app and select the Mootboard Virtual Mic in Discord or Zoom
Import WAV, MP3, FLAC or OGG clips
Configure and reorder effects or load a named preset
Assign global hotkeys to soundboard clips

Verdict

Mootboard combines a configurable effect rack with hotkey-triggered sound clips and a virtual microphone. It is free and locally processed, though platform support is limited to Windows and macOS for now.
