Abstract

There are several modern methods to visualize sounds, from oscilloscope and spectrometer to colour organs and strobe lights. Phase space is a relatively new way to visualize sounds. Originally used to better understand the chaos of strange attractors and other non-periodic systems, it can be used to observe the regularity of periodic and pseudo-periodic signals. Besides extracting information and interesting complexity of sound signals, these phase space images are attractive and compelling to look at.
