'shareware' and 'professional' are not usually compatible terms, but
you could try the program "Armadillo" which we have developed here at
the University of Illinois at Urbana-Champaign. It doesn't yet allow
a choice of analysis windows (it uses Hamming), but it has a variety of
diplay possibilities (1D, 2D, 3D, waterfall), does real time as well as
non-real time analysis, and you can print the images. Input is microphone
or CD-ROM (real time) or sound file (non-real time).

You can download this program for free from anonymous@cmp-nxt1.music.uiuc.edu,
directory pub/armadillo. The package includes a sample sound file and
extensive documentation.
