As a feature request, it would be great to look at both dBFS/ETC and % scaling simultaneously. I would prefer dBFS scaled ETC in conjunction with the Impulse with % scaling, the ETC trace is a lot cleaner and provides roughly the same information. :)

Thanks John.

There may be some information in IEC 60268-21, but I don't have a copy of it, rather pricey document to purchase. The references I am looking at are from Klippel. Page 16-19 of this presentation, with calculations from IEC 60268-21 shown on page 25...

Just one more thing to note. REW 5.31 is generating an out of bounds exception when I run stepped measurement for THD vs frequency. The measurement continues despite the error. REW V5.31 running Azul Systems, Inc. JRE 1.8.0_402 64-bit on Windows 10 Locale: language en, keyboard CA...

Ok, follow up question / feature ask. In the RTA Stepped Measurement, there is THD vs Frequency, THD vs level, IMD vs level, but not IMD vs frequency. The idea would be to run subsequent RTA in a similar manner to THD vs frequency, so a relative IMD level could be determined per set of...

I think you know that I had not :) Amazing stuff John, thanks! You've opened a whole new can of worms in my loudspeaker evaluations.

Hello, More of a general inquiry / feature request. I am wondering if there is any plan to add a multitone distortion plot, similar to what Klippel shows here: https://www.klippel.de/know-how/measurements/nonlinear-distortion/multi-tone-distortion.html Most of the functionality already exists...

I must have, oops, my bad, I thought I had unchecked those boxes. I was using the limits earlier to divide two measurements with different frequency spans, so limited to only frequencies common between both responses.

Hi John, I have created an exception in REW, attempting some trace division of two RTA captures " A / B" or " |A| / |B| ". A copy of error is below, and file attached so you can attempt to reproduce it. REW V5.31 running Azul Systems, Inc. JRE 1.8.0_402 64-bit on Windows 10 Locale: language en...

Thanks! I'm mostly looking to create screenshots using the same settings, and get a consistent image of the same dimensions that isn't dependent on the REW window size at the time of pushing the capture button. Defining the aspect ratio is probably the best method, alternatively, allow manual...

Hello, I was sure that in previous REW releases I could select the aspect ratio for capturing screenshots on the Distortion tab, but currently I am looking at a greyed out selection with "as plotted" as the only option. What am I missing?

That must me it, I am viewing this information using the AMD64 Linux build. The vertical line is better for frequency determination, but still can be difficult to determine amplitude for a slice in the middle of the plot. I am able to export the impulse response as WAV and view in ARTA, so I...

Hello, I have been working with the REW Waterfall view recently, and have a few questions / requests. 1. Perspective. Can the perspective angle be set for more of an "isometric" or "constant perspective" type of view? I set for X=15, however perspective angle is not constant so the view angle...

Thank you.
