Few users reported the same issue with our mastering eq, Pulsar Modular P440 Sweet Spot.
Here is what one says:
Most people (including myself) use the Audio Montage (not Audio Editor) in Wavelab for mastering work.
So, create a new montage. Import an audio file. Insert P440 on the Clip Effect slot (that’s what I did and use most of the time anyway) with Oversampling on.
Then play back the file repeatedly and listen for the first 1 second or so. There are random clicks/pops, sometimes not noticeable, and other times pretty loud.
The same happens when rendering the file. The clicks/pops are always happening differently and in different places (but always within the first second or so of playback).
The workaround solution is adding 2sec of silence before each song we are mastering.
We don’t have this issue in any other DAWs, including Nuendo and Cubase.
