+ *\r
+ * \section Sec_Compat Demo Compatibility:\r
+ *\r
+ * The following list indicates what microcontrollers are compatible with this demo.\r
+ *\r
+ * - Series 7 USB AVRs (AT90USBxxx7)\r
+ *\r
+ * \section Sec_Info USB Information:\r
+ *\r
+ * The following table gives a rundown of the USB utilization of this demo.\r

+ * \section Sec_Description Project Description:\r
+ *\r
+ * Audio Output host demonstration application. This gives a simple reference\r
+ * application for implementing a USB Audio host, for USB Audio devices using\r
+ * the USB Audio 1.0 class profile.\r
+ *\r
+ * By default, the demo will produce a square wave test tone when the board\r
+ * button is pressed. If USE_TEST_TONE is not defined in the project makefile,\r
+ * incoming audio from the ADC channel 1 will be sampled and sent to the attached\r
+ * USB audio device instead.\r
+ *\r
+ * \section Sec_Options Project Options\r
+ *\r
+ * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.\r
+ *\r
+ * <table>\r
+ * <tr>\r
+ * <td><b>Define Name:</b></td>\r
+ * <td><b>Location:</b></td>\r
+ * <td><b>Description:</b></td>\r
+ * </tr>\r
+ * <tr>\r
+ * <td>USE_TEST_TONE</td>\r
+ * <td>Makefile LUFA_OPTS</td>\r
+ * <td>When defined, this alters the demo to produce a square wave test tone when the first board button is pressed\r
+ * instead of sampling the board microphone.</td>\r
+ * </tr>\r
+ * <tr>\r
+ * <td>MICROPHONE_BIASED_TO_HALF_RAIL</td>\r
+ * <td>Makefile LUFA_OPTS</td>\r
+ * <td>When defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.</td>\r
+ * </tr>\r
