Odd Wafeform behavior in 7.4

[EarHole]

So, I printed a mix yesterday and the waveform just looks weird to me. I did a search and saw a few threads pertaining to incorrect
waveform drawings, but couldn't tell if this was what everyone was referring to.

Hi,
as far as I can tell you from here, it's not looking like an incorrectly drawn waveform, but it looks like you have a DC offset in your audio, and some sections are clipped (maybe partially resulting from the offset).

[EarHole]

It looks clipped but sounds fine. There's barely any compression on it at all. It's just dialog.

Does it correct itself if you 'recalculate waveform overviews'?

[EarHole]

Nope. It doesn't, nor does it do anything if I apply the DC Offset removal.

I"ve had this happen, too. And also, I haven't found any significant answers.

In my cases, it seems to be related to the plug-ins. Particularly the Drawmer plugs. It's not DC offset, the original files are clean.

Since I stopped using certain plugs, I've not seen this in a while.

FWIW

I disabled all plug-ins and no change other than lower levels.
I also did a bounce to disc and then imported it and it's the same thing.

I've seen similar things too, but I'm certain in my cases it was not a Pro Tools problem. Sometimes production dialog comes in that way (battery troubles) and I've even seen a VO guy whose voice looked like that every time! What's interesting about yours is that it is obviously not DC offset. Is the different waveform also a different recording? I'm guessing yes.

If it sounds good, so it is.

What is it doing in your scope??? When i have seen this happen it usually has to do with excessive information <10Hz. When viewed on a phase scope, the mono information will still be vertical, but the whole image will drift/pull pretty hard off center. The easiest way to check/fix this is to run an audiosuite high pass filter on it set to 16-20 Hz. (I use a Q2). that usually makes it go away.

Yes, the waveform changes when the pick ups come in. I think they were shot on a different day.

I initially had a high pass set at 40 Hz on it.
