    Distortion showing in measurements

    Apologies I was on 'play' instead of 'save to file' thank you.

    Ah that would be why I can't find it! The option isn't there for me, I'm on the latest version 5.31.3 too!

    Distortion showing in measurements

    I've just run a test with my laptop and a 1M long USB cable as well as the 5M long one. Those issues are still there. Could this be a problem with the UMIK1? I saw on the MDSP forums that a batch of them (not my batch apparently) had some issue that presented itself like this.

    I'm not able to find a way to add any sort of timing reference to the signal generator? Any suggestions? *Edit* I've just run a test with my laptop and a 1M long USB cable as well as the 5M long one. Those issues are still there. Could this be a problem with the UMIK1?

    Yeah I'll make sure to add acoustic timing reference. I thought the shield might be a good shout as I can drop the file straight to it over the network and I also have some demo material as well as a 'spatial audio' calibration kit that Technodad made, not sure if you've heard of it. It may even...

One running the sweeps from the HTPC (I could use the TV in my cinema to view that) and a separate instance of REW in my cinema on the laptop with the Mic attached to it...

    Distortion showing in measurements

    So I tested out REW on my laptop and had the same distortion at 1/2/3khz etc. And a lot more low end distortion between 100-400hz. So this tells me that the problem is likely the USB cable. My problem is that cable is routed from the AV rack where the HTPC & AVR is in the room above my...

    Distortion showing in measurements

    Thankyou for the info. Could potentially be the length of the USB cable between the mic and hub or mic and NUC. I have a 5M USB cable between the NUC and where I am measuring. Then the UMIK1 cable is 5M too but I tried a shorter one on that and it didn't make a big difference. I'm going to...

    Distortion showing in measurements

    Hi all hoping for some help. Getting back into REW after installing some room treatments. Today on the waterfall graph on all 7 bed layer speakers I noticed some odd results landing at 1/2/3/4k and so on. I decided to check distortion graph and it showed up there too. Can anyone suggest what...
