EQ 8 and Phase Issues

Post by LithiuMind » Tue Sep 11, 2012 6:32 pm

I have noticed that in certain cases, EQ 8 introduces delay to the track it is used on. (About .045 ms for me)

Specifically I noticed this when HI-Q mode is engaged. You can test this easily by aligning two duplicate tracks, phase inverting one of them with the Utility device, and then inserting a Hi-Q EQ 8 on one of the channels.

Interestingly, at 96khz project sample rate this behaviour disappears.

Can anyone comment on this? Is this due to the delay created by a linear phase EQ?

Are there any other devices which would create this kind of delay?

It is said that oversampling creates delay.
