Demonstrates how to build functioning examples of two Audio Unit extensions and a simple Audio Unit host app for iOS and macOS with the version 3 Audio Unit APIs.

The Audio Unit Extensions API introduces a mechanism for developers to deliver Audio Units on both iOS and OS X using the same API and also provides a bridging mechanism for existing version 2 Audio Units and hosts allowing them to work with new version 3 Audio Units.

The targets in this sample are all prefixed by their respective platform designation, "iOS" or "OSX":

- FilterDemoApp, FilterDemoAppExtension - Effect Audio Unit - InstrumentDemoApp, InstrumentDemoAppExtension - Instrument Audio Unit - AUv3Host - Audio Unit Host
