any kind of software that can make 3d plots like this or similar:

geological survey

karwendel

from freq, amplitude, etc..

(just pics will be nice too).

Edit:

windows only, guys..

I remember Wavelab had (has?) something like that.

Mathematica?

Mathematica is nice, but it is for developers

wavelab, wavosaur - both too far...

What do you need? Realtime? Static data set? VST? Standalone? Mac? PC?

Static, windows.

Thinking gnuplot can handle the 3D plot. Then the question is getting the data... you need something that can take an audio file and spit out a spectrogram/FFT as a text format time series that can be used for the graphing... Was thinking SoX could do it, but while it does have the ability to both convert an audio file to text, and also has a "spectrogram" function for spitting out a 3D spectrogram as a PNG file, it doesn't look like you can spit out a spectrogram as a text file. Boo!

How 'bout this hack... use this guy's flash hack to generate the text file: http://spectrogram.org ... take the resulting text file and plot in gnuplot. Complicated, free, and hacktastic! Only 256 bands though...

The must be a command line tool out there to generate a text spectrogram from a WAV file... such a common process...

Or, of course, you could simply use the SoX spectrogram function to generate a PNG file, then simply use the PNG file as a "height map" for your 3D terrain... common thing done in game programming, 3D work, etc....

http://www.wavosaur.com has this built in. It's free.

yeah gnuplot can do the trick...

Python, mathlab, mathematica, superCollider can do the trick too...
And all not user friendly, of course.

wav to mp3 / mp3 to txt / txt to png

Praat can export wave data as text and Spear as text frames, text partials.

3D plots from frequency, amplitude
