I'm currently doing this in TCL/TK. I started using the snack audio library which (anong other things) makes spectrograms. I give it consecutive chunks of audio and have it redraw to the canvas every n milliseconds. I think it's having trouble keepingup, and it only knows how to do 2d plots. I'm considering doing the processing beforehand (ie, on load) and storing the entire time-domain fft into a matrix, then using a graphics library (plot3d) to graph it in real time... unless I can figure outhow to multithread the program to allow one function to read ahead while the other graphs it. Anyway, I've never programed tcl/tk before, but I'm trying to get this done before january. -tewner > On Sun, 3 Oct 2004, Dave Phillips wrote: > >> HiAndres: >> >> At last, someone's going to try it ! :) >> >> I'm hoping that you're thinking of a realtime display, in which the >> peaks roll off to create a true waterfall effect. >> >> Stanko Juzbasic has tried to port Alan Peever's Spectrogram from SGI >> machines to Linux, but I've not been able to get his sources built >> on my >> systems. >> >> Please keep me informed about your progress, I've wanted such a >> program for many years. >> >> Best regards, >> >> dp >> >> >> >> Andres Cabrera wrote: >> >>> Hi all, >>> I am planning to develop a 3d fft display (sometimes called cascade >>> display), since I haven't found an application that does that in >>> linux. >>> Does anyone know if such an application exists or is in the works? >>> >>> Cheers, >>> Andr?s >>> >>> >> >> >> >
