Sonic Visualiser is one of the programs I've been using to view/analyze my audio. It is freeware but it's a pretty decent prog imo. It does have many options to adjust your Spectrogram and a couple other options to get creative with. I mostly use it to listen to my techno tracks ;)
Another nice option this prog has is where ever you put your mouse over gives you a dialog box in terms of Time, Frequency, Pitch & Phase.
