Audio class-specific Streaming Audio Interface Descriptor (USB-IF naming conventions). More...

#include <AudioClassCommon.h>

Data Fields

uint8_t bDelay
uint8_t bDescriptorSubtype
uint8_t bDescriptorType
uint8_t bLength
uint8_t bTerminalLink
uint16_t wFormatTag

Detailed Description

Type define for an Audio class-specific streaming interface descriptor. This indicates to the host how audio streams within the device are formatted. See the USB Audio specification for more details.

See also
USB_Audio_Descriptor_Interface_AS_t for the version of this type with non-standard LUFA specific element names.
Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

uint8_t USB_Audio_StdDescriptor_Interface_AS_t::bDelay

Delay in frames resulting from the complete sample processing from input to output.

uint8_t USB_Audio_StdDescriptor_Interface_AS_t::bDescriptorSubtype

Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSInterface_AS_SubTypes_t enum.

uint8_t USB_Audio_StdDescriptor_Interface_AS_t::bDescriptorType

Type of the descriptor, either a value in USB_DescriptorTypes_t or a value given by the specific class.

uint8_t USB_Audio_StdDescriptor_Interface_AS_t::bLength

Size of the descriptor, in bytes.

uint8_t USB_Audio_StdDescriptor_Interface_AS_t::bTerminalLink

ID value of the output terminal this descriptor is describing.

uint16_t USB_Audio_StdDescriptor_Interface_AS_t::wFormatTag

Format of the audio stream, see Audio Device Formats specification.
