USB Audio Devices.pdf
The Audio Device Class Definition applies to all devices or functions embedded in composite devices that
are used to manipulate audio, voice, and sound-related functionality. This includes both audio data
(analog and digital) and the functionality that is used to directly control the audio environment, such as
Volume and Tone Control. The Audio Device Class does not include functionality to operate transport
mechanisms that are related to the reproduction of audio data, such as tape transport mechanisms or CDROM
drive control. Handling of MIDI data streams over the USB is directly related to audio and thus
covered in this document.
