Abstract
Phase distortion and group delay distortion are defined. Examples are given indicating quantitative amounts of phase distortion produced by loudspeakers, anti-alias filters and analog magnetic recorders. A frequency-dependent tolerance on group delay distortion is developed based on numerous perceptual studies. Three new phase sensitivity experiments are proposed to assess more fully the perceptual significance of phase distortion in music reproduction with conventional electroacoustic transducers.
