The Broadcast Wave File format has been an essential part of the professional audio world for a good few years now. Like everything else the format must evolve to continue meeting the requirements demanded of it by contemporary audio production and processing needs.

Scope

The group has been created to work on three tasks related to BWF and RF64:

1) to add loudness metadata to the format;

2) to clarify the specification of the calculation of the FileSecurityCode;

3) to consider ways in which multi-channel audio formats that have no specific loudspeaker positions associated with them, for example Ambisonic B format, should use dwChannelMask.
