Sonnox De-Buzzer Reverb

I’m trying to use Sonnox De-Buzzer to get rid of an electronic feedback noise. I can isolate the frequency fine, but when I render the file, De-Buzzer seems to add a dose of reverb to the recording. Sounds as if the people talking are now in a large room. I have double-checked all of the settings to see what might account for this, but don’t see anything obvious. Can anyone help? :confused:

Nobody has any ideas? :question: :neutral_face:

No idea really, but are you saying it sounds fine when you listen through the De-Buzzer before the render, but then the render has the reverb? And no other plugins in the path? Also, can you try it on a different type of recording with the same settings and see if you still get it?
