<div>Hi list,<br>
<br>
</div>
I am searching for tool that would allowed me to
align sound system.<br>
</div>
I would like send sound impulse to one speaker and
get delay time (ms) based on captured signal by
measurement mic.<br>
</div>
For top speakers impulse could be about 2.5 kHz I
guess.<br>
</div>
A bit more complicated situation could be for aligning
top speaker and subs probably impulse of crossover
frequency would be necessary.<br>
</div>
That mean 60Hz 80Hz or 100Hz depend on system XO.<br>
<br>
</div>
Any suggestion how to achieve this? GUI CLI whatever

waterfall displays available for the PC.</p>
