Unfortunately I cannot show the Noise Removal on this test node because once again the display for the VST plugin is somehow not displaying correctly.
That should be fixed in the latest 9.02 beta.
Also I am already testing if it is Wavosaur. Using 8.23 and the same 7500 fully licensed. If this goes 100% it is not Wavosaur but Stereotool 9.01, I will let you know later on.
That's not really a guarrantee, but if 8.23 is ok, the chance that it's Stereo Tool does increase. Normally, or at least that's how it should be, a program like Wavosaur should create a separate instance of Stereo Tool for each file, to get rid of any history (very loud or very soft end of the previous song could affect how the new song gets processed). If it does indeed create a separate instance every time, then EVEN if something would go completely wrong in Stereo Tool, the next track should be fine again.
If you saw the output is silence, does that really mean that the scope line is drawn in the center? Or is there no scope line visible at all?
