Spectrum3d : software that displays the harmonics of the sound in 3D

Hello Mike


I'd like to introduce Spectrum3d, a new software that displays harmonics of the sound in 3D, with openGL.

Audio source can be the microphone or an audio file, and it is Jack compatible. Optionally, it can be run in real-time when not runing with Jack; also optionally, it can receive multitouch input (either from touchscreen, or from touchpad). 

X represents frequencies, Y represents amplitude of each frequencies and Z represents time. The perspective can be changed either by rotating or by translating the display around or along the 3 axis without limitations.

Here is a quick link to a demo video :  http://www.youtube.com/watch?v=CCVxDNbcqRE

It can be found here : http://www.presences.org/download/spectrum3d-0.2.2.tar.bz2

And here is a link to a tutorial explaining how it works : http://www.presences.org/spectrum3d_tutorial_en.html

It is free and under GPL licence. It uses the Gtk+, SDL, OpenGL, Gstreamer and uTouch-Geis free librairies. It works on Ubuntu 10.04, 10.10 and 11.04, but should work on other distributions also.  It is still beta; testers are welcome. Thank you for your attention.


             very nice victor.. is this yours? are you submitting it up to debian? 


Yes I did it myself; i didn't submit it anywhere but I would be very happy to. 
Do you think they could be interested? i thought maybe start with Ubuntu since it is the sytem I'm working on. On the other hand, I think that in Debian the Xorg implementation doesn't allow multitouch input for now ( but it can work in the testing branch AFAIK); but the 'mutitouch' is not the main feature of the software...
