Ok, Jesse, let see the screenshot unlimited.gif -- this is track
exported from Ardour, so level decreased by some value already.
If I process track (with decreased by panner level) in Audacity with
Hard Limiter(-7) i got screenshot audacity_-7dB.gif
If I export track (with decreased by panner level) from Ardour with
Hard Limiter(-7) activated i got screenshot ardour_-7dB.gif
audacity_-7dB.gif MUST BE equal to ardour_-7dB.gif, 'cause all
processing was done AFTER panner, but it isn't.
Am I wrong?
