Just to satisfy my curiousity can anyone on here recommend me a (preferrably free/shareware) program that will calculate average/peak volumes, perform spectral analysis, etc.. from common audio formats. Thanks in advance.

This one works fine; you need VST bridge plugin (if you don't have one)

Try Adobe Audition.
