The purpose of IEC 62680-1-6:2019 is to create a higher level of interoperability among Hosts and Audio Devices. By establishing a set of essential audio features, users can expect a consistent experience, Device manufacturers have a solid template to follow, and Host drivers may be simplified. The USB Audio Device Class Definition for Basic Audio Functions applies to all USB Audio Functions that are based on the Universal Serial Bus Device Class Definition for Audio Devices Release 3.0. It defines baseline audio functionality for all ADC 3.0 compliant Hosts and Devices.
