'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(at), directory pub/armadillo. The package includes a sample sound file and extensive documentation. James W.
