1 应用范围 本文详细介绍了用于双信道串行传输数据的推荐接口标准AES3,可定期取样并线性显示数字音频数据。 这种用于传输音频数据的格式可适用于任何被认可的取样频率,即AES5推荐方法中为专业数字音频应用,使用脉冲编码调制(PCM)而选用的取样频率。需注意的是这种接口规格并不要求设备都采用这些取样码率,并且使用其它的码率并不意味着设备只支持这些码率,所以设备规格应该定义所支持的取样频率。
1 Applications This document details the recommended AES3 interface standard for dual channel serial transmission of data that samples and linearizes digital audio data on a regular basis. This format for transmitting audio data is applicable to any approved sampling frequency, which is the sampling frequency chosen for professional digital audio applications using Pulse Code Modulation (PCM) in the AES5 recommended method. Note that this interface specification does not require the devices to use these sample rates, and using other rates does not imply that the device supports only those rates, so device specifications should define the sampling frequencies supported.
