After switching back and forth with the sample rate it started to work again. No idea what was wrong.

HI John, I get a strange sound from acoustics timing reference, Im not 100% sure if it started with last update of REW. Check link to listen to the strange sound. Any idea what is wrong? Check file, Timing ref REW.m4a...

Thanks, I got it to work again. Changed the chosen sample rate in sound card setting from 48 to 44.1 and now it works. Many thanks.

HI John, Thanks for helping out. My external sound card is a Behringer UMC22. Everything was working 2 month ago when I last did some measurements. Did some troubleshooting below. Maybe you can understand what is wrong from that. Or if you want me to test something else? Test 1: start PC...

Not getting Java performance working any more. I start up pc with my external sound usb connected. If I start YouTube I get sound to the receiver. If I now start REW and use Java as always have done the sound is redirected to pc speakers. But if I change to ASIO the sound goes to receiver. So...

This was very interesting but a bit hard to understand. So I must add a few follow up question just so I know I understand it correctly. So what we measure here is the combined sound during all 500 ms, okey. Is our hearing also working in same way, that we sum the direct and up to 500 ms late...

Hi, sorry for late reply. I had problem to find time from family to take the measurements. Attached are mdat with and without EQ. I included both output L and R since there are some differences. Why, I have no idea of?? I have connected my external soundcard to the CD rcas and running stereo...

The GD a XO is quite good, I think. But at around 35 hz the GD gets increased due to EQ. is this normal? Yellow: SUbs and L with EQ Blue: SUbs and L no EQ Purple: Only subs no EQ Red: Main L no EQ EQ:

When adding EQ to the subs, should there be an increase in group delay? And what is acceptable GD below 100Hz?

I used the "Align phase at cursor" ad the new line match you blue quite good. Maybe this is all wrong, but I was playing around at tried this feature. Anyway, I´m quite sure the 80-a are vary sensitive to mic location since its no more then +-1cm from when I took the original measurements...

Evan if its for sub only? Should I take measurements in all seats first for L and then for R speaker. And create average for input to EQ or how to best to this?

I have done verification measurement on your input. I guess you would like to see the results of your good work. - The XO60 verification looks good for both suggestions. - The first recommendation (SWs delayed by an additional 5.5 ms) (called _a_ in file) for XO80 did not align with the...

When measuring for EQ purpose should I run L or R or L+R from REW Tone generator?

Thanks for you input. I will now test the 4 different setting and check seat-to-seat and sound quality. I might add 1-2 EQ filterns to reduce the strong 43hz peak to get better understanding of the sound quality.

Also, how are you analysing to not recommend 90 or 100hz XO from my data?
