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

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

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

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

Size of the descriptor, in bytes.

ID value of the output terminal this descriptor is describing.

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