To use this feature, you need to have at least two IAA compatible applications installed on your iOS (iPhone, iPad etc.) device, first acts as a host and receives audio stream, and second acts as a node (or instrument) and publishes an output. Also, IAA node can transform audio or MIDI signal sent by host app, and return it in a modified form.
