  *  Audio demonstration application. This gives a simple reference
  *  application for implementing a USB Audio Input 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 microphone. Incoming audio from the ADC channel 1 will
- *  be sampled and sent to the host computer.
- *  
- *  To use, connect a microphone to the ADC channel 1.

+ *
+ *  On start-up the system will automatically enumerate and function as a 
+ *  USB microphone. By default, the demo will produce a square wave test tone
+ *  when the board button is pressed. If USE_TEST_TONE is not defined in the
+ *  project makefile, incoming audio from the ADC channel 1 will be sampled
+ *  and sent to the host computer instead.
+ *
+ *  When in microphone mode, connect a microphone to the ADC channel 2.

  *  Under Windows, if a driver request dialogue pops up, select the option
  *  to automatically install the appropriate drivers.
