Technote 29: Computing Group Delay from Phase Data Using APWIN. Group delay is a property of a device or a system: a plot of the change in phase of the response as a function of frequency; it is the negative derivative (slope) of the phase-vs-frequency characteristic of a device. Constant group delay across the frequency band means that all ...

sample delay effect being used in this tutorial, the group delay is constant over frequency, and is equal to the overall time delay measured previously. If the phase response of the system is not linear, the group delay at frequency f indicates the amount of time delay experienced by a small group of frequencies, which are centered about f. 1.
SUBWOOFER GROUP DELAY - Audio Design Guide
http://www.audiodesignguide.com/Sub/SIGroupDelay.pdf
SUBWOOFER GROUP DELAY Group delay has been found to be a major predictor of the "tightness" or transient accuracy of a subwoofer system. Group delay, in it's mathematical form, is the negative derivative of acoustic phase with respect to♪ requency. That is, group delay is a measure of how fast the acoustic phase of the system changes.
