Frequency-domain differences track perceived distortion better than time-domain ones
Evidence
Spectral distance measures. These measures are based on the notion that the magnitude spectrum and spectral differences reflect better the perceptual attributes of sound than signals or signal differences in the time domain. The difference between smoothed time–frequency presentations of a signal and the communicated signal often produces usable information about the distortion in the system. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2390
