REW V5.20 beta 11 Windows 64-bit installer

Changes in V5.20 beta 11:

• Added 192 kHz to the list of Java sample rates for all platforms and made changes to improve behaviour at 192k
• Restore the previous generator signal selection after checking levels, doing a soundcard calibration or making a stepped sine measurement
• Increased the measurement name field width on wider screens

Thank you for the new version John, it's much appreciated.

REW V5.20 beta 12 Windows 64-bit installer

Changes in V5.20 beta 12:

• Replaced the RTA "DR" figure by A-weighted noise plus distortion in the current Y axis units
• Added a basic scope data export capability
• Bug fix: Predicted response was not updated correctly when loading a measurement with filters
• Bug fix: Measurement sweep could be shorter than intended for some combinations of start frequency, end frequency and total length
• Bug fix: RTA file processing would not give a result for files the same length as the...

I think import sweep recordings is broken since Beta 11. It doesn't ask me to pick between L/R channels of the stimulus anymore, and the recorded FRs look different than what I was getting in Beta 10.

I think import sweep recordings is broken since Beta 11. It doesn't ask me to pick between L/R channels of the stimulus anymore, and the recorded FRs look different than what I was getting in Beta 10.

It no longer needs to ask for a channel to be chosen for the stimulus file, it checks both for the information it needs. It should still ask which channel of a captured sweep should be processed. Make sure the sweep file being used is from the current version, there have been some small changes to the sweep generation through the V5.20 beta releases which can affect the lowest and highest frequencies if a recording from an earlier sweep version is used. I have added a version check for the next build to prevent an earlier file being used.

REW V5.20 beta 13 Windows 64-bit installer

V5.20 beta 13 changes:

• Updated sweep file version number and added check that files loaded are the current version before using them
• Changed input and output scaling controls to use "FS sine" instead of "0 dBFS" so the figure is independent of the "Full scale sine rms is 0 dBFS" setting
• Generator voltage level display now uses V, mV, uV or nV according to the value. Values change in steps of 0.1 dB when using the arrow buttons.
• Added an option to capture the graph image in...

REW V5.20 beta 14 Windows 64-bit installer

Changes in V5.20 beta 14:

• Added Analysis options to automatically correct any difference between the input and output clock rates when using an acoustic timing reference or when using a loopback as a reference
• Soundcard calibration measurements check for and correct input/output clock rate mismatch
• Added manual clock adjustment in the Impulse graph controls
• Added a headroom figure on the filters panel showing the impact of any overall gain in the filter set
• Use longer...

FYI Beta 15:
I just decided to use the relatively newer feature 'measure from file' on my REW notebook for the first time running beta 15.
It indicated the new sweep file that I just created using beta 15 was not the current version needed.

 

[John Mulcahy]

Are you certain you chose the sweep file REW had just generated? If so, please attach it.

 

[jtalden]

Sorry! Today that same file is loading and the measurement worked properly.

Hi John,

I updated to V5.20 beta 15 and I am trying to shift an impulse peak by a certain number of samples however it does not look like it's moved to where I am expecting it to in relative time. In the example on the screenshot; I was trying to shift this impulse from it original position by 634 samples which should equate to 13.208ms but it was shifted by 14.376ms instead. Are my calculations wrong?

 

[John Mulcahy]

What's the sample rate of the measurement? For that delay it should be 44.1 kHz.

 

[Breeman]

Thanks John, that was the issue. The sample rate of the impulse is 44.1 kHz. How can I get REW to calculate the delay correctly for this sample rate? Changing it to 44.1 kHz in Preferences does not seem to work.

 

[Breeman]

Hi John,

I would e great if you could consider adding an option to keep the Preference screen on top too. On my computer when the main program is maximized to full screen, it disappears as soon as I move the cursor away from it. Clicking on its icon in the taskbar does not really work as it disappears again. The only way I get it to work is by minimizing the main program which is not ideal at times.

That is the correct delay for 44.1 kHz. 634/44100 = 14.376 ms. The delay is based on the sample rate of the impulse response whose zero time you are changing.

Having Preferences always on top could be a bit problematic due to its size and some parts of it needing to launch other windows. Ctrl+shift+e also opens the Preferences window if REW has focus, or brings it to the front if it is already open.

The behaviour sounds odd though, have you enabled focus follows mouse to cause that? That can be turned off by unticking this Control Panel option: Control Panel > Ease of Access Centre > Change how your mouse works > Make It easier to manage Windows > Activate a window by hovering over it with the mouse. Note that the option is not accessible via Settings. It can also be turned on by an option in nVidia's nView program, I believe.

That was itSomething had changed my Windows settings for the mouse. Thank you so much John.

Hi John,

Just a small request. Could you please consider adding the displacement of an impulse in samples, in the graph control menu of the impulse tab? Currently when one utilizes the "Estimate IR delay" button, the Cumulative IR shift is shown in time and distance however not in samples. I am only asking because REW already has the option to offset an impulse in all three options.

 

[John Mulcahy]

Sure, I have added that for the next build.

REW V5.20 beta 16 Windows 64-bit installer

V5.20 beta 16 changes:

• Calibration files for soundcards are now linked to the output device name and the sample rate, the required file will be loaded automatically if the device or sample rate change provided it has been specified
• Calibration files for input devices (microphones, SPL meters, ...) are now linked to the input device name and the input channel, the required file will be loaded automatically if the device or channel change provided it has been specified
• All...

Hello,

I was attempting to try and route REW sweeps thru JRiver for the purposes of confirming the correction applied from my Convolution FIR files but it appears that the "INPUT" channels are Greyed out within REW when choosing JRiver as the Output.

Is this the expected behavior? If so, I'm not sure how I can tell REW which Input my MIC is connected to if by chance that Input is something other than Channel 1-2.

If I change the ASIO Deice to my Lynx Hilo ASIO the Input Channel becomes active again.

Thoughts?

Thanks

 

[John Mulcahy]

ASIO generally only supports a single device, so it looks like the JRiver Media Center device has no inputs. There are applications that create ASIO wrappers around multiple devices to circumvent that limitation, such as ASIO4All and FlexASIO.
