Thanks, I've fixed it for the next build.@John Mulcahy there seems to be a minor visual bug in the RT60 graphing:
It's present on both the Mac and Win ea36 builds.

At the moment probably only if the DAC is fed externally using REW's signal stored to a file.Would it be possible to add the ability to set a separate sample rate for the DAC and ADC, ideally using EXCL? I'd like to measure the DAC's response close to Nyquist, without the ADC's own Reconstruction filter affecting the results.
If I could set the DAC to play at 44.1kHz and the ADC to record at 96kHz or higher, then that would be super.
I know and I share the pain in case of stepped tests... This time I dream of client-server architecture added to the REW, to let control another REW instance.Feeding the DAC externally is what I'm doing at the moment.
For some frequency response measurments though, I like to use the stepped sine method instead of the usual sweep or noise.
And for that, REW must control both DAC and ADC.
Hi John,For those folk that like to stick to IEC263 aspect ratios for graphs:
- Added: The SPL & Phase, All SPL, Overlay SPL and Overlay Predicted SPL graphs have an IEC263 aspect ratio control to force them to a preferred ratio. If a ratio is selected the margins around the graph will be adjusted to achieve the specified dB/decade. At very narrow frequency spans the margins will be prevented from growing too large and the aspect ratio can no longer be maintained, the actual aspect ratio can be shown on the graph by selecting that option in the View preferences.
The measurement file dialog already allows multiple selection. You need to click on the files display to use selection shortcuts.Also really nice would be the ability to load multiple measurements in the CTRL+O and CTRL+I dialogues:
Meaning have the shortcuts operate as they did previously, changing the SPL range to fit the aspect ratio? Changing the SPL range generated quite a bit of push-back from folk that want to stick to an IEC 263 ratio, hence the more comprehensive solution in the latest build.Can the "as-plotted" view mode remain when selecting 25db/dec options for the preset view buttons?
I simply mean to treat aspect ratio and IEC263 display as two separate selections, so selecting 25dB/div in the view preferences doesn't automatically change the view mode to IEC263 constraints.For myself, making the most use of the screen space would be a priority, which would mean for 20-20kHz dispaly at 25dB/div aspect, horizontal width is maximized and vertical scale range is dynamic based on window size. Selecting +/- buttons on vertical scale breaks the aspect ratio, as does right click zoom, so one option that allows for maximum use of screen space would be to simply disable manual vertical scale adjustment for locked aspect ratio, change +/- button selection here to aspect ratio selection instead is a possibility.Meaning have the shortcuts operate as they did previously, changing the SPL range to fit the aspect ratio? Changing the SPL range generated quite a bit of push-back from folk that want to stick to an IEC 263 ratio, hence the more comprehensive solution in the latest build.
Hi,John,where's the latest build version for download?Builds updated today with the changes below. Note the preferences bug fix, the Java runtimes default system preferences implementation could ignore REW's attempts to use file-based preferences, that has now been addressed.
- Added: Multiple selection is now possible in the file dialogs for import frequency response and import impulse responses, though drag and drop may be easier.
- Added: The span and aspect ratio of the Impulse graph magnitude view can now be configured in the graph controls
- Changed: A frequency span preset aspect ratio will only change the graph aspect ratio selection if the selection is not "As plotted"
- Changed: Apply a minimum span for fit to data
- Fixed: The IEC 263 aspect ratio preference key was not unique for the All SPL graph so the chosen ratio could be forgotten
- Fixed: The Java runtime default preferences store could override the file-based preferences
