So I came across a website that does custom art printing based on Spectral transforms of your favorite music. That got the wheels turning.
I really like this, its more subtle than a lot of cliche musical oriented pics I've seen (my opinion). So I tried to look for a program that could do the transform for me. I'd like to play around colors and then create a jpeg of the appropriate size. Then I could order an art panel, so its a win-win on decor and acoustics.
Does anyone know a good program for making such a spectral transform? I have ARTA but haven't played with it. I could use matlab at work, but it's graphics manipulation aren't so hot but it can do the transforms pretty easily.
So basically, programs like Spek can make the "map" for you easily, but I haven't figured out how to export a picture or be able to manipulate the colors. The transform is fairly basic math by today's standards. Its a FFT of the input signal (in this case an MP3 or whatever) where frequency is the Y axis, X is time and Z is the intensity in dbs (i.e. heatmap). In theory I could do this with something like ggplot2 in R, but I'm hoping to have something a little less "Y" in the DIY.
