Hello.

This is the first time I use REW. Big thanks for the REW team.
I use the V5 beta.

I have a PC with windows xp pro 32bits and an EMU 1820m. I would like to use REW to perform some measurements in my room before and after audyssey multiEQ XT. I own an audyssey calibration kit and I'm going to use it with REW (but I can not use the calibration file coming from audyssey).

This my soundcard calibration curve, I think it is well but I would like a confirmation before to go to the step 5.

Thanks & best regards

I'm not sure why there is a ripple there, but given the amplitude is on the order of 0.1dB, I figured it didn't matter. It did not look big enough to me to suggest any sort of feedback problem.

You may find the ripple behavior changes slightly when you use a different sampling rate. I believe the general advice, if you play with the sampling rate, is to use whichever one gives the smoother calibration curve.

Hi Bill and thanks.

I will try with the sampling rate at 48, my soundcard can handle it.

Regards

EDIT : this is the curve with sample at 48. I'm going to use this configuration.
