IEC 62942:2019 

File format for professional transfer and exchange of digital audio data


Do you need a multi-user copy?




IEC 62942:2019 specifies a file format for interchanging audio data between compliant equipment. It is primarily intended for audio applications in professional recording, production, post-production, and archiving.
It is derived from the AES31-2 [2] but is also compatible with variant specifications including EBU Tech 3285 [3] to [10], ITU-R BR.1352-3-2007 [11] to [14], and the Japan Post Production Association's BWF-J [15].
This document contains the specification of the broadcast audio extension chunk and its use with PCM-coded audio data. Basic information on the RIFF format and how it can be extended to other types of audio data is given in Annex E. Details of the PCM WAVE format are also given in Annex A.
An optional extended format, BWF-E, supports 64-bit addressing to permit file sizes greater than 4 GB.
