Sketches and Plots

Infinitewave sweep plotted by the MATLAB toolbox. That is:

x = wavread('infinitewave-sweep.wav');
xcqt = cqt(x,50,48000,24,96000);
contour(abs(xcqt.spCQT));

Same sweep, first Yeti version. Time alignment between octaves is not yet correct, and there is visible aliasing from decimation.
