Overview
A free, open-source soundboard and voice changer for Windows and Linux, fully vibe coded with AI. Its Rust audio engine mixes your mic with sound clips into a virtual microphone that Discord, OBS and games can pick.

What I built
- Fully vibe coded: I directed AI coding tools through the whole project, from the Rust audio engine to the interface.
- A real-time audio engine in Rust decodes clips, mixes them with the mic and feeds the virtual mic, with no allocations or locks on the audio threads.
- On Linux, Kavox creates its own Kavox Mic through PulseAudio or PipeWire and removes it on exit. On Windows it plays into the free VB-CABLE driver.
- Mic passthrough with clock-drift correction: a PI controller holds the mic buffer at 20 ms, tested against ±1000 ppm drift with no underruns.
- A live voice changer: a granular pitch shifter with presets like Chipmunk, Giant and Wobbly, a pitch dial and a hotkey per voice.
- Pads with drag-to-reorder, multiple boards, global hotkeys, a setup wizard, a tray menu and a kavoxctl CLI.

The problem
My friends and I wanted a soundboard to use on calls and in games, but the good ones are paid. I decided to make my own and release it fully open source, so we could all use it for free.
Outcome
It's free for anyone to use, and my friends and I use it. It's been really helpful.
