for my project I needed to view the Audio Spectrum CHOP in TOP as an image. But when you do this with Chopto TOP, you don't get the Audio Spectrum CHOP graph (amplitude against frequency). When you do this with OP Viewer TOP, you get a spectrum graph as TOP but the max amplitude keeps shifting up and down and the graph lines are still present. I needed to get rid of these problems and get a pure spectrum graph with fixed max amplitude.
So I wrote a short python script which achieves this. I'm not expecting anything, but I though I could make this available in case someone needed a similar thing. You can of course change stuff. I included a description of the code inside the Text DAT which might help you understanding and changing the script.
I hope this helps someone!
