Alan,
Audacity - it's free. It does both audiograms and power spectra and is
worth putting up with a few fiddly wrinkles.

Sorry to be picky over the terminology but "peak frequency" can be
taken to mean the highest frequency or the frequency at the highest
level which is really the peak power frequency which can be anywhere
in the call.
If I have a variable pitch call I would select the peak frequency
(highest frequency) and plot the power at that frequency on the power
spectrum. If I want the peak power frequency (over the lenght of a
call) the power spectrum plotted over the whole call provides this.
