Where's this phantom noise coming from??

Firstly, Happy New Year to everyone!

Now for the unpleasant bit: my EQ (both in Pro-Q and Ozone) is picking up disconcerting background noise even with no audio playing (see screenshot). At first, I thought it might be coming from my computer, on which my audio interface is standing, but when I moved it away, the noise remained.  

Does anyone have an idea what this could be?

What other plugins and instruments are on all the tracks and buses feeding that one?

Some plugins generate noise as part of their function; it may be so low you can't even hear it but still be able to see it in an analyzer view. 

 

Is input echo on for any track?  General input noise can also do that.

Agreed. Disable all the plugins in your project to see if the noise disappears. Some plugins can generate noise even though the project is not playing. Guitar amp plugins and some Waves plugins can be guilty of this. One Waves plugin that springs to mind is Waves H-Delay which has an analogue option (which you should set to ‘off’), but there are others.

Thank you all for your useful input. I was able to find the culprit - I switched off each Vst one by one in the Synth Rack and was able to pinpoint Analog V! Pity because this soft synth has several nice instruments. But, the noise is not audible, so I guess I can get away with it. Unless this could cause frequency buildups in time?

Can you pinpoint which preset of which synth in Analog V is causing the noise?  If possible, maybe you can edit the preset to eliminate just the noise component of that preset.  However, you will need the full version of that specific synth the do the edit.
