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

#include <AudioClassCommon.h>

Data Fields

uint16_t AudioFormat
 
uint8_t FrameDelay
 
USB_Descriptor_Header_t Header
 
uint8_t Subtype
 
uint8_t TerminalLink
 

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_StdDescriptor_Interface_AS_t for the version of this type with standard element names.
Note
Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

◆ AudioFormat

uint16_t USB_Audio_Descriptor_Interface_AS_t::AudioFormat

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

◆ FrameDelay

uint8_t USB_Audio_Descriptor_Interface_AS_t::FrameDelay

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

◆ Header

USB_Descriptor_Header_t USB_Audio_Descriptor_Interface_AS_t::Header

Regular descriptor header containing the descriptor's type and length.

◆ Subtype

uint8_t USB_Audio_Descriptor_Interface_AS_t::Subtype

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

◆ TerminalLink

uint8_t USB_Audio_Descriptor_Interface_AS_t::TerminalLink

ID value of the output terminal this descriptor is describing.
