Audacity is pretty darn easy to use (and also free) - just rip a file from CD, open in Audacity, and there you go - you'll get a graph like the ones above. You can zoom in, etc, for different views (to actually see the clipped waveforms on the Dixie Chicks, for example).

(It's also easy to make a file of test tones using Audacity, your choice of frequency and duration.)
