About BBX Audio

We are an indie plugin company focused on developing the next generation of vocal production tools for modern beatbox artists, vocalists, and sound designers.

As vocal-driven creators ourselves, we’ve seen how far the voice can go; from raw performance to fully produced sound. And yet, until now, the tools available haven’t truly reflected that potential. While DAWs and generic vocal processors offer some solutions, they often fall short when it comes to the unique needs of beatboxers: real-time responsiveness, percussive detail, sub-frequency shaping, and intuitive vocal routing.

With BBX Audio, we’re developing a dedicated suite of plugins designed to bring beatbox and vocal performance into the world of modern music production. Our tools are zero-latency, stage-ready, and built to give vocalists the same level of creative and technical control producers have always had with instruments. Whether you’re sculpting snares, tuning subs, or building full vocal drum kits; our goal is to put that power directly in your hands.
