Broadcast Wave file question
We’re being asked for Breakcast Wave files of a 5.1 mix. I have everything as aiff now, and am assuming from what I can gather on the web that a broadcast wave file is simple a linear PCM, 16 or 24 bit, 48khz .wav file. Yes/no?

sounds right to me.

You didn’t mention the reason you were being asked for files, so, just in case, are you sure you know what they want?
Do they want the six stems that make up the 5.1 channels or are they after a Stereo mixdown?
Other than that, your original assumption is correct. -
A broadcast wav looks to many systems just like a wav file. However in some audio systems the embedded timecode stamp can be read and used to sync the file to a specific timecode reference.
If you need the timestamp then Sebsky tools can convert broadcast wav files to QT files so that FCP can read the timecode.

FCP, as of 5.1.2, will read BWF natively.

This is what they’re asking for: Dolby is striking a Dolby Digital track for print:
I found tools that convert the TC stamp for FCP, but I need to go in the reverse direction – aiff to BWF
