IEC 62942, "File format for professional transfer and exchange of digital audio data", was published in December 2019. It is primarily intended for audio applications in professional recording, production, post-production, and archiving. Edition 1 2019-12 is based on and compatible with AES31-2-2019. It is also compatible with variant specifications including EBU Tech 3285, ITU-R BR.1352-3-2007, and the Japan Post Production Association's BWF-J.
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.
This is the result of much effort by the SC-02-08 Working Group on Audio-File Transfer and Eschange, led by chair Mark Yonge.
