[maxmsp] Re: (off-topic) Sonogram visualisers

Let me conclude:
There are lots of sonogram visualisers:
- Frequency
- Amadeus II
- AudioXplorer 1.2 (real-time) http://www.arizona-software.ch/audioxplorer/
- http://www.sonicvisualiser.org/
- http://www.klingbeil.com/spear/
- http://www.birds.cornell.edu/brp/raven/Raven.html
- scilab
- Sonogram Visible Speech
- Pratt analyser, 
- Mixviews
 and I can add praat (if pratt is a different program)

That's far too much software to get to know and to use...
I would like to use a sonogram which can be scrolled over a time distance of more than a few seconds. And it would be wonderful, if pitch can be seen easily. Audio sculpt should do all this. Is there cheaper freeware with the same features?
