Latency Measurement of your Audio Interface


How to measure the latency of your audio interface?

If found my way to measure what I wanted to measure.

I wanted to measure the delay my DAW needs to get a external signal and output it again. Actually it is possible to do it with one computer, but I wanted to separate the measuring system (my laptop) and the measured system (DAW).

The idea is to generate a white noise signal with a duration of 100 ms, repeated every 1 second and to send this signal from another computer to the DAW. I also connected the return signal from my DAW to the first channel of my laptop (measuring computer). Beside this, to eliminate the unknown latency of the measuring computer, I connect the other second output channel of the computer to the second input channel of the computer.





First of all you need the test file I generated using Octave. You can download the test file or generate it by yourself using the script.






Final latency: 8.62 ms
