The USB Audio Class Driver is a part of the Jungo USBware framework and is fully compliant with the USB-IF Audio Class Specification. It enables an embedded system to recognize an audio device and provide real time streaming audio. Using the Audio Class Driver, users can communicate with their USB audio device, streaming audio to or from the USB device.

The Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as storage devices, keyboards, joysticks, printers, scanners, modems, and digital cameras.

A USB Class Driver is a Logical Device Driver (LDD), which controls USB devices that provide common functionality and are implemented in compliance with a specific device class.

A USB Function Driver is a driver implemented within a device in order to handle the device-specific functionality of a standard or custom USB device function. This driver provides the counterpart of the USB Class Driver.

Jungo's USB Audio Class Driver is part of the Jungo USBware USB Host Stack, which enables software and device manufacturers to incorporate standard USB connectivity into their embedded devices.

The USBware Audio Class Driver streams the audio data through a dedicated isochronous pipe, thus utilizing the full potential of the USB bandwidth while guaranteeing required throughput and minimizing protocol overhead.
