"Listening to these pulse signals, with six selectable spectrum shapes, is very revealing of loudspeaker time smear (driver "hangover," crossover misalignment, cabinet diffraction, and so on), frequency response colorations (particularly from resonances), and room effects such as discrete echos, standing-wave bass modes, and acoustic colorations in general. You can hear quickly, and with detailed clarity, the speaker's degree of image focus, transient precision, and tonal neutrality."
