Description

The Audio Test Bench provides a graphical interface through which you can develop, debug, test, and tune your audio plugins in real time. You can interact with properties of your audio plugins using associated parameter UI controls. See audioPluginParameter for more information.

Using the Audio Test Bench, you can:

  • Debug your audio plugins.

  • Simulate your audio plugins as generated in a digital audio workstation (DAW).

  • Visualize your processing with time-domain and frequency-domain scopes.

  • Interactively synchronize MIDI controls to plugin properties.

  • Run validation checks and generate audio plugin binaries.
