Latency compensation

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

Re: Latency compensation

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.
