Hello, I made a crude sonogram https://gist.github.com/2983547 with the note names instead of the frequency. But, It really angers me not to be able to have a log scale for the frequency.
Does any well known workaround exists? Is there an easy way to grosso modo do : x = time, y = frequency, z=amplitude of spectre with something like a specter of one croche at time = t according to the bpm and make an y scale logarithmic, then project the amplitude (z) with a colormap on x,y plane according to the amplitude, and and have 3D representation? Basically, I guess it boils down to know if combining those 2 is possible : http://matplotlib.sourceforge.net/examples/mplot3d/contourf3d_demo2.html + log scale for y. I guess I could improve the result by using logscale on Z and colormap (http://stackoverflow.com/questions/5748076/python-matplotlib-contour-plot-logarithmic-color-scale) Since it is only for fun, and I don't want to invest myself too much my question is really did I missed something while googling for an easy solution and if so, what are the good keywords?
