This is a revision of the ‘Guideline for Federal Agency Use of Broadcast Wave Files’, initially published in September 2009.
It defines levels of metadata to be embedded in digital audio files and recommends actions cocerning data elements in the BEXT chunk established as part of the Broadcat WAVE (BFW) file specification by the European Broadcast Union.
The background documents providing the context and further explanations to the guidelines may be found here.
