REW Beta Release REW API beta releases

[JoinUs]

From the mdat I see you are using Trim IR to windows and then exporting the trimmed IR. Trim IR to windows ensures the resulting IR length is a power of 2. If that power of 2 length went past the end of the available data zeroes were prepended to the IR. I have changed that for the next V5.40 beta build. For your exports it would make more sense to use the "Apply IR windows before export" option instead of trimming the IR.

Thank you for your quick feedback.
Yes. It's a habit for me. Letting out after burping.
So if I use Apply IR windows before export in IR exporter, is there no such problem? (
So is something changed for that trim in 5.30.9 and 5.31, right?
In versions before 5.31, I couldn't try to recreate that. )

I am not sure what I am doing wrong, but ever since I have installed the beta version, the right click on the legend panel is missing the option to copy the selections to the other overlay graphs. I only see these three options.

I bet I am missing some step. Please advise.

John,

Somewhere in this part of the script (and it's in a loop) sometimes a Java Exception is thrown. It could be other unclosed script pages running in the background causing this but I am sharing anyway:

PS There's nothing related to RT60 in the script!

 

[John Mulcahy]

I bet I am missing some step. Please advise.

Make selections using the measurements on the right, they are the same for all overlay graphs.

 

[John Mulcahy]

Somewhere in this part of the script (and it's in a loop) sometimes a Java Exception is thrown

That and the previous post are errors caused when a measurement whose RT60 data is being generated is removed. RT60 data generation can be triggered by various events, including selecting a measurement.

 

[serko70]

It's an extremely rare outcome but any suggestion I can catch or avoid that error? Or is an inhibitor for that kind of background operations possible?

 

[John Mulcahy]

If you are changing the currently selected measurement try and avoid that. If you are deleting measurements don't do it too quickly after generating them.

 

[JoinUs]

Hi John,
I don't know if this is possible, but I ask you.
Is it also possible to remove only toal harmonic distortion components from the measurements recorded as REW? (Like extracting a minimal phase or an access phase)

 

[John Mulcahy]

Not sure I follow, but the impulse response from a sweep measurement is the linear response of the system excluding any harmonic distortion components.

 

[John Mulcahy]

Builds updated today (beta 56) with these changes:

• Pro upgrade: Added calculation of speech transmission index by the indirect method per IEC 60268-16:2020
• Added a custom clarity trace with a control to set the division between early and late time in the graph controls
• Added an API endpoint /measurements/max-measurements to retrieve the maximum number of measurements allowed
• Added API RTA endpoint commands to save the graph image to file or copy it to the clipboard
• Added API RTA endpoint /rta/image-capture-settings to read and configure the options for saving or copying graph images
• Changed: Room simulator allows sources to be placed with their acoustic centres flush with room surfaces
• Changed: Delay cleanup after measurement removal if calculations are running on it
• Changed: API SPLValues rollingLeqMinutes is now a double rather than an integer
• Fixed: Graph x axis frequency presets did not work properly if the chosen end frequency was too far beyond the range of the loaded measurements
• Fixed: Trim IR to windows could prepend zero-valued data to the trimmed IR
• Fixed: POSTing to /generator/full-scale-vrms gave different results depending on the "Full scale sine rms is 0 dBFS" setting

 

[HD MOVIE SOURCE]

In beta 56 does impulse timing change? I noticed my speakers have a 3 to 4ms change in impulse timing after updating. How exactly did impulse timing change?

 

[John Mulcahy]

In beta 56 does impulse timing change?

No.

 

[ManCaveAudio]

Yes.

With REW pro, what number of USB mic connected for multi seats measurements?

 

[John Mulcahy]

With REW pro, what number of USB mic connected for multi seats measurements?

It is very unlikely that multi-input would work with multiple USB mics.

 

[linuxonly]

I apologize if it's a stupid question but do we need to uninstall 5.31.3 before installing the beta?

 

[John Mulcahy]

do we need to uninstall 5.31.3 before installing the beta?

No, no need to uninstall.

WIth IR-Windows POST API, addFDW = "false" seems to be ignored:

I have fixed that for the next build.

 

[serko70]

It is very unlikely that multi-input would work with multiple USB mics.

I have managed to run successful sweeps with two analogue + one USB mic (total of 3 mics) but didn't try 2 usb mics.

wow, you're full of tricks

 

[keantoken]

On this build and on the current stable build (Linux build and then WINE) I have an array out of bounds error whenever I try to generate minimum phase with tails and whenever I click on the Impulse tab for a measurement which I generated minimum phase data for.

(Linux build and then WINE

Just a note - do you have any specific reason why using the windows REW build under wine, instead of native linux REW build? Wine puts another layer into the audio path, and GUI programs have often issues in wine. Java runs OK in linux natively.

 

[John Mulcahy]

On this build and on the current stable build (Linux build and then WINE) I have an array out of bounds error whenever I try to generate minimum phase with tails and whenever I click on the Impulse tab for a measurement which I generated minimum phase data for.

Can you attach an example measurement that shows that behaviour?
