标准摘要
[中文适用范围]: 本文件是该设备类定义的3.0版本,详细描述了支持音频设备类的音频数据格式。本文件被视为音频设备类规范的组成部分,但本文件的后续修订独立于主要USB音频规范的修订演进。这样做是为了便于添加新的音频数据格式,而不妨碍核心USB音频规范。该文档定义了USB音频3.0设备类的数据格式,包括简单音频数据格式(Type I、Type III、Type IV)和扩展音频数据格式。它涵盖了传输分隔符、服务间隔和服务间隔数据包的定义,以及各类音频格式的具体规范(如PCM、IEEE_FLOAT、AC-3、DTS等)。 [外文原描述]: IEC 62680-1-7:2019 describes in detail all the Audio Data Formats that are supported by the Audio Device Class. This document is considered an integral part of the Audio Device Class Specification, although subsequent revisions of this document are independent of the revision evolution of the main USB Audio Specification. This is to easily accommodate the addition of new Audio Data Formats without impeding the core USB Audio Specification.
