Information technology — Coding-independent code points — Part 3: Audio — Amendment 1: Headphone support

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.
