Build for the shared Chaos Audio platform. Browser / FAUST: Write or generate code, then audition. Native C++ / JUCE: Build a compatible ARM .so with the toolchain. Test on hardware: Check sound and CPU before public submission. Use the current Dev-Portal guides. Desktop VST/AU files are not hardware plugins.

Start with the current documentation

Chaos Audio Dev-Portal explains the plugin contract, real-time safety, builds, hardware testing, and Tone Shop submission. Use the main branch’s current guides rather than older “9 KNOB” test-effect instructions.

Know the boundaries

  • A desktop VST, AU, or AAX file cannot simply be installed as a hardware effect. It must be developed/ported for the Chaos Audio format.
  • Native NAM playback in the products is separate from the developer NAM SDK, which the Dev-Portal still lists as planned.
  • Browser audition does not replace checking CPU load and audio behavior on hardware.

Use an existing plugin in your DAW

If you want to install available Tone Shop effects on a Mac or Windows computer rather than develop a hardware effect, see the desktop plugin installer guide for supported formats and current early-access limitations.
