I received what look to by typical mono mix stems .wav files from a Protools mix session. When I go to import a single stem I end up with a stereo track that appears to be to mono stems with the same name as the original mono mix stem. It gets weirder when the tracks for say the full mix which are named the same for both channels with the difference being the suffix.
To be specific when the "Auto Detect Broadcast Wave Mono Groups" is checked on if I import "Santa Rosa ST MIX.L.wav" I end up with a stereo track where both tracks are labeled "Santa Rosa ST Mix.L.wav" If I do the same with the "Santa Rosa ST MIX.R.wav" I end up with a stereo track with both tracks also labeled "Santa Rosa ST Mix.L.wav". Turning off the feature and I get the normal mono tracks I would expect to get. I'm not sure how Avid detects these Broadcast Wave mono groups, is it based on the tracks names and why would both the right and left stems come in as stereo tracks with both tracks labeled Left.
That was the issue I first noticed then today on a different project at work I exported an audio only .mov using direct out of an standard 8 channel 5.1 LtRt mix stems. I ended up with a .mov with 8 discrete tracks that I used QT Pro 7 to change the track assignments from mono to their corresponding proper assignents of L,R,C,Lfe,Ls,Rs,Lt,Rt. Then I ran Videotoolshed's Audio Map program, which I think I called QT Map in a thread earlier this week, and that produced 8 .wav stems each with a suffix of _1 thru _8 which correspond to the individual tracks from the audio only 8 channel QT .mov. When I ama link media to any one of the individual clips I end up with an 8 channel clip. I went and made sure to uncheck the autodetect broadcast wave mono groups in the import settings but that seems to have no effect on ama linking.
As was suggested a few weeks back in order to change the time code on the wav files to match the sequence time code I downloaded the free Wave Agent program. When I changed the time code on the first "_1" file it actually changed the time code on all the individual wav files. When I bring any one of the 8 wav file into wave agent they show the correct modified time code and the Channels Column shows "8(MONO). I'm curious how these wav files are all linked. Is it based on file name or is there something in Audio Map when it strips the 8 discrete channels from the .mov to create 8 .wav files that creates metadata embedded in each of the files that links them together. I haven't had a chance to check much with the resulting files but they do import and link back into Avid with the correct starting time code I modified using Wave Agent so everything is working but I'm curious if Avid has a bug detecting Broadcast Wave Mono Groups and does it base it's imports and linking on just the file names or some other metadata present in the wav files?
When I originally stripped out the wav files using Audio Map the files all show a 10 hour something time code when brought into Wave Agent. That's where I changed the start time code to match the sequence start of 00:59:00:00 24 frame code. I have no idea where the original 10 hour something code came from as the QT 8 channel .mov that was used by Audio Map had matching time code to the sequence.
So many little metadata devils to line up. It would really be nice if Avid would just export direct to .wav with matching timecode to the sequence. It does export but all the .wavs start at zero time code in my experience. Does anybody know of a way to make Avid do what I need?
