I put all the tracks on my album Symmetry-Breaking through spectrogram software to visualize the audio, then stacked the images together with IrfanView. They are all shown to the same scale, so the image width is proportional to the track length (the shortest tracks are 2:00 minutes and the longest are 6:00 minutes). The visualization shows the various forms of symmetry – and lack of it – in the structure of the tracks and in their arrangement within the album as a whole. Click on the image to enlarge.
Settings used for the spectrogram: Hann window, 4096 samples, 75% overlap. Scale: dBV, logarithmic frequency plot, 0-20kHz.
