Broadcast WAV file metadata


#1

I trust someone here knows something about this. EBU's broadcast wave format is used in radio station automation aswell as in other applications. The file extension is *.wav.

How does one read, add, edit or delete audio metadata in the sense that we know it in other file format such as mp3 and flac? Apparently mp3tag cannot be used for this purpose. How is this done and what tools are available to convert, say, a flac file or a 'standard' wav file to a broadcast wave file and then to include the kind of audio metadata one might hope to include: album, title, artist, composer, albumartist, genre, performer, comments, ISRC, date, record label, etc., etc., etc.?

Any pointers in the right direction would be greatly appreciated and you will be rewarded with good karma and luck in the future.

Thanks...

I am sure you know these informations ...

To transfer metadata from MP3 or FLAC files to WAV files you need a ready made utility to do so, or you have to develop your own workflow using several existing utilities.
At least you need an application, which can write a user-defined BWAV resp. BEXT chunk to the WAV file, following the EBU standard.
Search the internet for "EBU chunk writer" or so.
Have a look at Adobe Audition, Wavelab, Awave and other applications too.
You can use Mp3tag to export metadata to text output as usual.

Good luck!
Please report what you have find out.

Hi...

I have been all over your first two reference sites and found nothing actually useful that will help me create or import the desired tags to create a BWF file from a standard WAV or FLAC file. The third reference looks more interesting, because its a tool that I need to add, edit and read the audio tag results.

I'm surprised mp3tag doesn't have this capability. Here in the USA at least, and perhaps everywhere, BWF files are used almost exclusively by commercial radio stations for automation, but then what do I know? Our radio station is non-commercial, non-profit and most of our programmers use CDs directly to air.

I'll also continue to 'google' for the required utilities that can do this. I'll report on what I find, if anything.

Thanks.
