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 …

This can be calculated from group delay by dividing the group delay by the period of the frequency at each point. I call this "normalizing" the group delay by period. If you do this the frequency dependence gets out of the way of seeing the phenomenon. For example, consider the Blauert and Laws data on audibility thresholds for group delay.
Group Delay - Explanations and Applications
https://radio-labs.com/designfile/dn004.pdf
Group delay is a concept that radio engineers are encountering more frequently as higher performance digital communication systems are developed. It appears that frequency selective components have group delay which, in most cases, seems to degrade system performance. This article addresses several aspects of this topic:

The group delay is when you group other rooms tonyour theatre. The longer the delay the more stable the sound due to buffering... but it will impact the synchronization obviously. 1 More posts from the sonos community 292 Posted by 3 days ago After 6 months of saving i made the jump and joined the family. 49 comments 252 Posted by 2 days ago

It is then confirmed and proven that group delay at low frequencies is audible. This means timing - GD, phase - matter for sound in the bass range, it is not sufficient to tune towards a flat frequency response alone. I have provided sound samples so you can try and hear yourself. Last edited: Aug 20, 2019 I represent Kvålsvoll Design AS
What is the difference between phase delay and group delay?
https://dsp.stackexchange.com/questions/206/what-is-the-difference-between-phase-delay-and-group-delay
Group delay: Rate of change of the phase around this point in frequency. When to use one or the other really depends on your application. The classical application for group delay is modulated sine waves, for example AM radio. The time that it takes for the modulation signal to get through the system is given by the group delay not by the phase delay.
