   *  \section Sec_Description Project Description:
   *
   *  Audio demonstration application. This gives a simple reference
   *  application for implementing a USB Audio Output device using the
   *  basic USB Audio 1.0 drivers in all modern OSes (i.e. no special drivers
   *  required).
   *
   *  On start-up the system will automatically enumerate and function
   *  as a USB speaker. Outgoing audio will output in 8-bit PWM onto
   *  the timer 3 output compare channel A for AUDIO_OUT_MONO mode, on
   *  timer 3 channels A and B for AUDIO_OUT_STEREO and on PORTC as a signed
   *  mono sample for AUDIO_OUT_PORTC. Audio output will also be indicated on
   *  the board LEDs in all modes. 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.
   *
   *  \section Sec_Options Project Options
   *
   *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.

   *   <tr>
   *    <td>AUDIO_OUT_STEREO</td>
   *    <td>AppConfig.h</td>
   *    <td>When defined, this outputs the audio samples in stereo to the timer output pins of the microcontroller.</td>
   *   </tr>
   *   <tr>
   *    <td>AUDIO_OUT_MONO</td>
   *    <td>AppConfig.h</td>
   *    <td>When defined, this outputs the audio samples in mono to the timer output pin of the microcontroller.</td>

   *   <tr>
   *    <td>AUDIO_OUT_PORTC</td>
   *    <td>AppConfig.h</td>
   *    <td>When defined, this outputs the audio samples in mono to port C of the microcontroller, for connection to an
   *        external DAC.</td>
