You have very little to do with this. The "Delay" will be from the time it hits a scanner, then is sent through the computer to the network or internet service provider, then through that network of switches back to your home computer or phone network, then your software that puts this all back together so you can hear it. All of this is dependent as far as speed on weather you have fiber or copper as the phone lines in your area, and the condition of even your home phone lines. For instance: We are in a all fiber area but the individual streets have a copper backbone. After the change to fiber in the area I noticed a big improvement in network congestion and went to the highest speed access I could get, I then ran a dedicated line from my demark on the home to the modem/router in the house and noticed a huge improvement on things that I run most noticeable was my streaming video on Netflix. I did use cat5 cable because I have access to as much as I need. Don't forget webstar22's post.
