I can see how that might look a bit strange, but it does what it says and "repeats the effect" (the "effect" is to follow the amplitude envelope and then apply that as a gain curve).
If you don't want that, then (as you're aware trebor), you can use a duplicate track as the "control track".
Also, we don't really want to be retaining the envelope in RAM after the plug-in has finished as it could be quite large.

That's a good trick :)

Dynamics Processing

Dynamic Mirror
(dynamic-mirror.ny) download

Author: Steve Dalton

Is an envelope-follower : it applies the loudness-envelope of one track to the selected track(s) below it.
It can also apply the inverted version of the envelope of the control track to other track(s) below when in ducking mode, (so is a possible alternative to AutoDuck).

When only one track is selected Dynamic-Mirror will re-apply its envelope to itself, (or its inverse when in ducking mode). Applying in "mirror" mode, (i.e. envelope-follower mode), to self, causes dynamic-range-expansion. Applying to self in ducking-mode causes dynamic-range-compression.

If used on stereo-tracks, Dynamic mirror uses an average of the two track's envelopes.
So for some applications* you will need to apply it to separately to each stereo track,
(* e.g. if you want a flat envelope ).

however, applying different envelopes to a stereo track can cause a strange panning effect.
