/// \dir
///
/// !!!Purpose
///
/// This directory provides definitions, structs and functions for a USB Audio
/// Class device - USB audio-looprec demo, to implement an USB desktop speaker
/// which echos audio stream back to host.
///
/// !!!Contents
/// There are two things for the implement of the audio-speaker device driver:
/// - Implement the audio-looprec driver structs and functions for the device,
/// to initialize, to handle audio class specific requests and dispach
/// standard requests in USBD callbacks, to read/write through assigned USB
/// endpoints,
/// - Create the audio-speaker device's descriptors that should be passed to
/// the USBDDriver instance on initialization, so that the host can
/// recognize the device as a USB audio "desktop speaker" device.
///
/// This project is simply addon to the audio speaker demo. For more
/// information, please refer to "USB Audio Speaker Device".
