/** \mainpage Audio Output Device Demo
 *  
 *  Audio demonstration application. This gives a simple reference
 *  application for implementing a USB Audio Output device using the
 *  basic USB Audio drivers in all modern OSes (i.e. no special drivers
 *  required).
 *  
 *  On startup the system will automatically enumerate and function
 *  as a USB speaker. Incomming audio will output in 8-bit PWM onto
 *  the timer output (timer 3 for the AT90USBXXX6/7 USB AVRs, timer 1 for
 *  the AT90USBXXX2 controller AVRs) compare channel A for AUDIO_OUT_MONO
 *  mode, on channels A and B for AUDIO_OUT_STEREO and on the board LEDs
 *  for AUDIO_OUT_LEDS mode. Decouple audio outputs with a capacitor and
 *  attach to a speaker to hear the audio.
 *  
 *  Under Windows, if a driver request dialogue pops up, select the option
 *  to automatically install the appropriate drivers.
