Default Asymmetrical waveform (problem?) caused by 7-Band EQ 3

Hi. Please help. I just mixed a TV documentary with predominant sound being voice-over and talking heads. Everything sounds ok but my final waveform looks like this (the parts going below the line is voice-over, and the others, usually going above the line are talking heads recorded with lavalier mics). Hardly anything is symmetrical. I realized that the 7-Band EQ 3 causes this, as when I bypass it - it everything looks symmetrical. I use High pass filter usually around 90 Hz, low pass around 13khz and other equing between that. Other than that I use Renaissance compressor, Massey de-esser and L1 on master channel, but none of these causes that. Also, when I put a really steep Q10 filtering out everything below 100hz everything looks more symmetrical, but why would I do that. I thought it is a DC problem but I tried DC removal both on clips and the sections of bounced file but everything stays asymmetrical. By the way I am still on PT 7.3.1 with DV Toolkit.


Is this a normal thing, should I worry about this asymmetrical waveform?

Tnx!

very few things at truly symmetrical

I wouldn't worry unless it sounds off

If you have a proper monitoring environment and it sounds good, why would be a reason to worry???

Tnx a lot, I will not worry as it sounds good. but does anyone know why 7-band EQ is doing this, as I understand it has something to do with low frequencies.

Looks like a dc-offset. Try lo-cut at 20Hz.
