IEC 62680-1-7 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.

IEC 62680-1-7 详细描述了音频设备类支持的所有音频数据格式。 本文档被认为是音频设备类规范的组成部分，尽管本文档的后续修订版独立于主要 USB 音频规范的修订版演变。 这是为了轻松容纳新音频数据格式的添加，而不妨碍核心 USB 音频规范。
