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.
