* \section SSec_Description Project Description:
*
* 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.
*
* Under Windows, if a driver request dialogue pops up, select the option
* to automatically install the appropriate drivers.
*
* \section SSec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td><b>Define Name:</b></td>
* <td><b>Location:</b></td>
* <td><b>Description:</b></td>
* </tr>
* <tr>
* <td>MICROPHONE_BIASED_TO_HALF_RAIL</td>
* <td>Makefile LUFA_OPTS</td>
* <td>When defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.</td>
* </tr>
* <tr>
* <td>AUDIO_SAMPLE_FREQUENCY</td>
* <td>Descriptors.h</td>
* <td>Gives the audio sample rate per channel for the audio stream, in Hz.</td>
* </tr>
