The JAX DYNAMICS : Compander - a combination of a compressor and expander - is a single band dynamics audio processor, has different stereo operation modi (like independent stereo, linked stereo, independent mid/side and linked mid/side processing) and has a parallel processing option (mix) too. The JAX Compander is a dynamics processor in AudioUnit (AUv3) format. The audio unit itself (an app extension) is embedded into a small demo app. This is required for app distribution on Apple platforms. Installing the app will make the audio unit available for system wide usage with audio unit hosts (music apps), which support loading 3rd party app extensions in AUv3 format.
