My favorite spectrogram analyzer because is really fast and easy to use, even when it is buggy sometimes.
Used it a couple years ago. It did it's job good enough, even if it was a bit buggy. I liked it =)
Spek doesn't work on my Mac.
Audacity DOES work - R-Click the name of the loaded track,
choose spectogram,
then click "spectogram settings",
Scale>
MAximum Frequency>
Enter " 22000", which is the maximum for MOST files.
Very quick and easy to use. Does what it says on the tin. Found it very useful when comparing formats and conversion settings before re-encoding a large batch of needlessly high-quality files.
