Hi Mike,

thank you for suggestions, but only what I am searching for is to measure
delay in ms for impulse from two sources.
Most close what I've found is Fon's Jack_Delay which measure sound card
latency for set of tones.

(scroll down the page)

Only difference is I don't want link input and output of sound card, but
play to speaker and capture sound in mic.
And I would probably should just one tone instead of set.

best regards

mira
