- All audio/data transport goes "through" this platform-generic
-class. The AudioDevice implementations copies recorded data
-to this buffer and then signals that a AudioTransport callback
-shall be performed. Also - in the other direction - the AudioDevices
-informs this class when they needs more data to be played out, a
-callback is performed and data stored in the AudioDeviceBuffer.
-The AudioDevice implementations can then copy the stored data
-and play it out.

-mixer.
-
-
-
-

- The data flow is driven by the sound card (thread(s)) using
