This is the abstract base class for an audio device.
With an audio device we refer to any kind of (multichannel) audio input/output/fullduplex. AudioDevices are usually created by the AudioManager. The interface for the user however, are the AudioIn and AudioOut classes.
Each AudioIn and AudioOut created is registered with the AudioManager. When the AudioManager is started, it will create the appropiate AudioDevice or AudioDevices, based on the number of inputs, outputs, operating system and AudioIOConfig of the AudioIn and AudioOut objects.
