信息技术 - 独立于编码的代码点第3部分:音频

[中文适用范围]： 本文件定义了各种代码点和字段，这些代码点和字段独立于压缩编解码器和比特率，建立了音频流的属性。这些属性可以描述解码后的音频数据的适当解释，或者可以类似地描述信号在被适合压缩该输入信号的编码器压缩之前的特点。 [外文原描述]： ISO/IEC 23091-3:2018 defines various code points and fields that establish properties of an audio stream that are independent of the compression encoding and bit rate. These properties could describe the appropriate interpretation of decoded audio data or could, similarly, describe the characteristics of such signals before the signal is compressed by an encoder that is suitable for compressing such an input signal.
