REW Beta Release REW API beta releases

[HD MOVIE SOURCE]

I haven't encountered that and can't reproduce it. I can try adding something in the next build, but without a way to see the same behaviour it will be just guesswork.

Note that if you want to rename a measurement for the individual graph selectors (i.e. the ones you see for SPL & Phase etc) right click on the name.

I'll see if I video capture it at some point.

Can you attach the measurements you had loaded?

 

[John Mulcahy]

Builds updated today (beta 74) with these changes:

• Added: The EQ window filter adjust graph has an action to copy filters from another measurement
• Added: The RTA peak finder includes a musical note column
• Fixed: Impedance measurement level check sent the test signal to the ref output instead of the measurement output
• Fixed: Room simulator could exhibit odd behaviour after setting a reference trace
• Fixed: Loading an mdat file via the API when not using a GUI caused a null pointer exception
• Fixed: Inverting the IR when an octave band filter was applied did not retain the inversion when the filter was removed

Added: The EQ window filter adjust graph has an action to copy filters from another measurement

Thanks.

Thank you for the feature. I would like to report a bug regarding the Copy EQ Window Filter.
Of course, it appears to be applied in both Predicted and Filters, and even when I export it by clicking "Generate Measurement from Predicted," the graph still reflects the applied changes.

However, the EQ filter window does not display the EQ values. (Although the thumbnail of the very first peaking filter has changed.)
To resolve this, I need to activate any other measurement first and then switch back to the original measurement's EQ tab to see the applied changes.

And I record screen. You can check

 

[John Mulcahy]

I would like to report a bug regarding the Copy EQ Window Filter.

I have fixed it for the next build.

Builds updated today (beta 75) with this change:

• Fixed: Copying filters from another measurement did not update the filters panel

 

[keantoken]

I cannot import audio sweeps, WAV gives a false samplerate error and FLAC causes an error.

 

[keantoken]

My mistake, I think the WAV file is actually the wrong format, but the FLAC file still triggers an error log.

 

[John Mulcahy]

The WAV file has an incorrect riff chunk ID (875972178). The FLAC file imports fine for me, what error are you getting? You can generate a diagnostic file from the REW help menu to capture all error info and attach that.

 

[keantoken]

When I drag and drop the FLAC file as the stimulus file, I get this error.

When I drag and drop the FLAC file as the stimulus file, I get this error.

The stimulus only supports WAV files, the file has embedded content to identify the sweep settings.

 

[John Mulcahy]

When I drag and drop the FLAC file as the stimulus file, I get this error.

I have fixed FLAC support for sweep recordings for the next build, but to preserve the sweep config data the stimulus FLAC file should be generated from a 24-bit PCM WAV sweep file.

 

[decompositions]

Is there any way to control the RTA graph appearance and/or graph image save dialog via the API? I've gotten to the point of being able to save the graph by posting the below to /rta/command, but when trying to figure it out myself parameters doesn't appear to support named parameters as an object and just expects an array where only the filename seems to do anything, and the graph appearance options don't seem to be present on any of the other rta configuration endpoints. The use case here is that I'm trying to script a series of rta measurements and I'd like to be able to change the axis of the graph depending on what I'm trying to measure. I'd also like to be able to set the "image width" parameter, but that's more of a nice to have. I couldn't find anything hinting at this on the api documentation page or with search, so sorry if this is a repeat question.

{
    "command": "Save graph image",
    "parameters": [
        "C:/code/rew/test-out/graph.png"
    ]
}

 

[John Mulcahy]

The Swagger UI web page at localhost:4735 is the easiest way to browse or search endpoints. /rta/image-capture-settings controls the image capture dialog. There are no endpoints to change the graph axes, however.

 

[John Mulcahy]

Builds updated today (beta 76) with these changes:

• Added: /rta/y-axis API endpoint to get and set the graph Y axis
• Added: /rta/graph-limits API endpoint to get and set the graph left, right, top and bottom limits
• Added: /rta/cursor-x API endpoint to get and set the graph cursor X position
• Fixed: Serial number detection was not working for EARS cal files
• Fixed: Sweep stimulus import will accept FLAC files, but they should be generated from 24-bit WAV files to preserve the sweep config data

 

[AmigoHD]

Builds updated today (beta 59) with these changes:

• Changed: StormAudio equaliser limits and filter types updated

Glad to see more filter variants than just Bell have been added for StormAudio. Meanwhile with the latest betas (I did not try beta 59) exported shelf filters can't be imported into StormAudio PEQ because the .txt is missing the Q values. I first need to edit the .txt and add Q + value manually to it. But it's unclear which Q value REW has calculated.

 

[John Mulcahy]

Meanwhile with the latest betas (I did not try beta 59) exported shelf filters can't be imported into StormAudio PEQ because the .txt is missing the Q values.

Meaning the StormAudio shelf filters have adjustable Q? They didn't mention that (or I missed it), but I can change it in the next build.

 

[AmigoHD]

yes they do. to be precise there needs to be a value otherwise the filter can't be imported. same Q values are available as for bell filters. thx for looking into it

 

[Nvexx]

Hi there and sorry for asking. But is there any chance you missed something in the release notes after "V5.40 beta 72 2nd March 2025"? (so v73 and up) I'm asking this due to some issues I'm having with my script yet I can't find anything related to the issue in any of the release notes.

 

[Nvexx]

To give some more context:
Set a new default curve (house curve)
and Find the default 75dB flatcurve in REW (just a flat line curve @75dB)
Make a new response copy

if (name.endsWith(" @ ")) {
                        await postSafe(`http://localhost:4735/eq/house-curve`, targetCurvePathSPK, "House curve set");
                        await new Promise((resolve) => setTimeout(resolve, speedDelay));
                        await postSafe(`http://localhost:4735/measurements/${q}/command`, { command: "Response copy" }, "Completed");
                        await new Promise((resolve) => setTimeout(resolve, speedDelay));
 }

Generate target measurement from the copy by searching REW for the measurement title that ends with -copy

        measurements = await fetch_mREW();
        mCount = Object.keys(measurements).length;
        for (let q = 1; q <= mCount; q++) {
          const name = measurements[q].title;
          if (name.endsWith("-copy")) {
            await postNext("Generate target measurement", q);
            await new Promise((resolve) => setTimeout(resolve, speedDelay * 2));
          }
        }

Delete the -copy

        for (let q = 1; q <= mCount; q++) {
          const name = measurements[q].title;
          if (name.endsWith("-copy")) {
            await postDelete(q);
            await new Promise((resolve) => setTimeout(resolve, speedDelay * 2));
          }
        }

Find the new target measurement and rename it

        measurements = await fetch_mREW();
        for (let q = 1; q <= mCount; q++) {
          const name = measurements[q].title;
          const newname = "DEF SPKs Curve @" + Number(nvexx_ReferenceLevel_SPK).toFixed(1) + "dB";
          if (name.startsWith("Target")) {
            const requestOptions = {
              method: "PUT",
              headers: { "Content-Type": "application/json" },
              body: JSON.stringify({ title: newname }),
            };
            fetch(`http://localhost:4735/measurements/${q}`, requestOptions);
          }

Never had problems with this since my implementation and this allowed me to have "multiple" curves show inside REW. How ever since Beta 73 and up All the curves are off by around 3dB all of the sudden,

Beta 72

Beta 76

As you can see from 73 onward the curves are off all of the sudden by about 3dB ?

I don't see anything relevant in the commit history. The copy action was extended to allow multiple copies to be made at once, but I don't see why that should have affected your script. You could check the Info panel for the copies to see if they have different SPL offsets to their source measurements, and check nothing else has changed in the Target settings.

Yes, the Linux builds support the API. You can check the rew_output.txt and roomeq_wizardx.log.txt files for any errors logged (their location is shown in the About REW dialog), or use the Help menu option to generate a diagnostic file and attach that.
