CTA has recently published ANSI/CTA-6026, File format for professional transfer and exchange of digital audio data IEC 62942:2019. 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 but 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.
