Final question... high pass filter in Pro Q 3

Sorry about this... there's something fundamental I'm having a problem understanding. I'd like to cut everything below 20hz (for vinyl), so am setting a high-pass filter which ends at 20hz (in high res mode). However, I'm still seeing activity below 20hz in the post-eq analyzer. Should I adjust the curve until the analyzer shows a complete cut at 20hz. ...or am I overthinking this?

It has to do with the inherent limitation of analysers. They're simply not as detailed at lower frequencies.

Hi Bram

Thanks very much - this has clarified things for me... I thought I was losing the plot.

All the best
