Hi list,
I am searching for tool that would allowed me to align sound system.
I would like send sound impulse to one speaker and get delay time (ms)
based on captured signal by measurement mic.
For top speakers impulse could be about 2.5 kHz I guess.
A bit more complicated situation could be for aligning top speaker and
subs probably impulse of crossover frequency would be necessary.
That mean 60Hz 80Hz or 100Hz depend on system XO.
Any suggestion how to achieve this? GUI CLI whatever
The human ear can hear this quite well, I understand. I have a Behringer
crossover with adjustable delay built in and I think there's a procedure to
do this in the manual.
There are also software for speaker testing and design that I've seen.
The most complete seems to be available from Parts Express. I've also seen
software packages with things like waterfall displays available for the PC.

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
