Thanks to Julien and Rui Capela.  Being a musician and engineer, this seems to be a great place to land in and learn new stuff in this world of Linux audio.  Currently, I am still not able to find document that I need to solve 2 existing problems:

Question on using JDelay:

I have only one web source that has some details about using this tool:

http://www.kokkinizita.net/linuxaudio/   and this reads:  "It uses a phase measurements on a set of tones to measure the delay from the output to the input".

How do I use these phase measurements and how do I pass in these tones?  Are they special tones?  What kind of oscillator do I need to use to generate these special tones?  How do I pass in an audio tick or click?  How do I do other settings?  

$ jack_delay -h --help does not show me the help menu
