Mootboard is a free, MIT-licensed open-source soundboard and real-time voice changer for Windows and macOS.
What Mootboard is
Mootboard is a free, MIT-licensed 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. Users can chain effects, drag to reorder them, adjust individual parameters, and enable or disable each effect. Named presets save and reload complete effect chains. The soundboard plays imported WAV, MP3, FLAC, or OGG clips through configurable global hotkeys and mixes them into voice output. The README states end-to-end latency of ≤ 15 ms at 48 kHz with a 256-sample buffer. First-time setup installs a virtual audio driver and requires administrator access once on Windows or macOS. Processing runs in a Rust audio engine with a React interface inside a Tauri window. Supported systems are Windows 10/11 (x64) and macOS 12+ on Apple Silicon or Intel. Linux, noise suppression, accessibility, and OBS integration are listed on the roadmap.
Good
- Eight listed real-time audio effects
- Reorderable effect chains with presets
- Imports WAV, MP3, FLAC, and OGG
- Virtual microphone for chat apps
- Low stated end-to-end latency
Watch out
- Windows and macOS only
- Administrator access required during setup
- Linux support remains on roadmap
- No published releases shown
Who it suits
It suits Discord, Zoom, and game-chat users on supported Windows or macOS systems who want adjustable voice effects and hotkey-triggered clips. Users needing Linux or roadmap features should look elsewhere.
Verdict
Mootboard offers extensive effect-chain control and a soundboard routed through a virtual microphone. Platform limits, one-time driver administration, and roadmap-only features define its current scope.
