Hi,

Since we needed this in Sound Radix, we’ve added AAX AudioSuite (CHostProcessor) support to JUCE 4 & 5.

[soundradix/juce5](https://github.com/soundradix/juce/tree/juce5) is pretty much on par with 5.x develop branch.  
[soundradix/master](https://github.com/soundradix/juce) is currently 4.3.1.

- Remember! CHostProcessor behaves different than Native AAX running with AudioSuite property (for example: input number will be your maximum supported if in multi-input mode or mono).

- It was tested on Pro Tools 10.3.10 (32-bit) and Pro Tools 2018 (64-bit).  
(it doesn’t support older Pro Tools \< 10.3.5 as this is based on AAX API).

- AudioProcessor::wrapperType got `wrapperType_AudioSuite` (to allow code branching for CHostProcessor version…).

- AudioProcessor now has `analyseBlock` to allow analysis stage prior to `processBlock`.

- AudioProcessorEditor has `getCustomLabel` to allow customized naming on AudioSuite UI.

- We have random audio access encapsulated to `juce::AudioFormatReader`.
