Hi,

I need help regarding the measure in REW.
I got equalizer Apo and managed to put a fir filter using convolution. It is actually able to correct the phase reponse wich is great.
Now my wonder is to measure the "benefits" but now I am facing a difficulty. Since the filter generates delay for the correction of the phase, I got this delay while making a measure.
When the sweep starts, the sound is delayed by about 1sec and it end before executing the whole sweep, at 5Khz.
My measure is unusable.

So I would like to know if it's possible to put some sort of compensation delay due to the sound card latency in the software settings.

Thank you

Thank you I didn't know how to do so

Try using the acoustic timing reference and the new "Wait for timing reference" option in V5.15 beta 4, there is more about that in this thread.
