That's an interesting application.

It certainly has use, but it has a cost. By moving the phases you got the minimum
dynamic variance (and so the maximum average amplitude) but you lost the attack
transient. The kick drum seems a great example. Don't these 'super normalised'
short hits sound "duller" with less "impact" than their unprocessed sources?
My best guess for application domain is short vocal phrases.
