Volume reversed in audio visualizer?

I was playing around with the audio visualizers and noticed that in the Rgbarz, Bars, and Wavescope visualizers, the elements meant to be controlled by volume are inverse, such that the volume is pushing the various meter elements down rather than up as the volume increases. Is this the intended behavior? Are others seeing it as well? I can’t seem to find a way to reverse it, as much as I’d like to.

Yes, I believe on all effects you have elements that reacts on both directions with the sound.
