- *
- *  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
