You can generate periodic noise over custom bandwidths and look at the output on the RTA.

Using the room curve for that isn't a good approach with the response you have. If there was tons of excess low end response that might...

If you attach the mdat file I'll take a look at it, but performance on my test measurements is unchanged from earlier versions.

Builds updated today to fix lag/interface issues: Fixed: Some actions could trigger repeated smoothing causing interface problems and lags

If the behaviour is repeatable I can send you a debug build to try and work out hat is happening.

If there is some repeated calculation running you may see activity in the bottom right corner of the main window.

Anything more than 7 days old in the temp folder is deleted automatically on shutdown. There's really nothing for me to work with to...

No, nothing deleted. Works for me on every graph.

Input volume is the same for both and the SPL offset (derived from input volume and the cal file sensitivity) is the same for both, so...

REW only uses as many filters as it needs. It won't correct anything below the lowest frequency where the response drops below the...

If I can see a couple of measurement files that show the normal and reduced levels that will provide more info.

Builds updated (ea62): Fixed: Array index out of bounds when using trace arithmetic operations with an upper frequency limit

I have been able to reproduce that now and fixed it for the next build.

Can you attach a screen shot of the trace arithmetic settings you are using when you get the error on that measurement? Please also use...

No. Can you attach some example measurement mdat files showing the difference?
