Lets say I have a program like Skype and I call to my friend. I want to create a test to figure out what is the average delay from the audio, from my mic to his speakers.
I want to measure:
- delay in one instance of time
- delay over longer period (60 s)
Assumptions that i can make:
- at least 8000 samples per second.
- devices are in the same room and network propagation delay is negligible.
- external mic and photo-detector/camera should be used.
