What is group delay?

[egellings]

As long as they're all showing up at the same time, should not make a difference, n'est pas?

So long as there was not a specified arrival time, then yes.

If all frequencies arrive at the same time, then that is generally considered propagation time. For audio only, that may have no significant effects. However; if combined with video then it may be profound.

Depends upon whether it was past the host's bedtime.

How profound is the delay a 3’ cable versus a 6’ cable?
It might be profound in a GPS timing, or a CERN accelerometer… but does the TT and listener really care?

Can we describe group delay in this manner:- Suppose the musical scale Do Re Mi Fa So .... is in this sequence but coz of GD we might hear them not in sequence for example... Re Do Mi Fa So, for example ?

It seems easier to imagine the family in a line, and signifying all the “Doh Ray Me” simultaneously (in a burst).

However the father (capt Von Trapp) is further away and then Christy, and the kids from tallest to shortest are closer to you.
So while the sound started simultaneously, it arrived as “Doh Ray Me…”
