REW Beta Release REW API beta releases

[HD MOVIE SOURCE]

I guess you are using snap layouts. If you double-click a measurement to select it rather than using the EQ right click action that won't happen. I'll fix the behaviour of the EQ action in the next build.

Perfect, thank you.

what is wrong？I though it is reasonable frequency range，from 0 to 1.2k Hz

 

[dcibel]

What's wrong is the speaker clearly has a filter installed. Impedance is falling >1kHz. T/S parameters should be of raw driver only, and measurement from 0 to nyquist freq, or at least 20kHz.i would also be somewhat concerned of a 1 ohm load at high frequencies.

I wish to have phase shift simulation function in Alignment tool, same function with time alignment @John Mulcahy

 

[John Mulcahy]

How would that differ from what the delay slider does?

Phase shift is different from time delay. Here is the configuration in Audiotec Fischer, Helix, Brax or Match DSP

 

[John Mulcahy]

That doesn't tell me anything, sorry. If you are looking for an all-pass option then it would add extra settings (centre frequency, order) for little benefit (no benefit for most people). If you want something different please explain exactly what.

Sure, the API is just another feature that will be included in releases from 5.40 onwards. This initial beta doesn't have anything else that isn't in 5.30.2, however.

Stupid question here: Is API REW version means that we don't need a hdmi cable between the laptop and the avr?

 

[John Mulcahy]

The API is a way of controlling REW through another program, it doesn't change how REW connects to a system.

First time user. Trying to optimize my calibration with REW and A1 Evo, but I keep getting an error message that "target curve not found." I've uploaded the .txt target curve file to the EQ > House Curve menu as instructed.

Any tips?

For context, I'm using Google Chrome on Mac. I realized my Chrome wasn't the latest version, so I just updated Chrome and restarted the process, and got the same error message. My MacOS is also not updated, so I'm installing the latest OS update now and will retry this process in the morning.

That's an A1 Evo issue, not an REW issue. You might try asking over in the A1 EVO Acoustix discussion on AVS.

It's because that's an older version of OCA's code, which is no longer up to date with the API. The AcoustiX version is current.

wow thank you! I must've clicked the wrong Youtube video which took me to that outdated A1 Evo version.

Got everything to work with AcoustiX－game changer! Thank you all again.

When making a SPL offset (dB) to a graph and it is applied to data, is it possible to read afterwards the actual applied offset in the Info tab? For those (like me..) who forget to write it down.

I'm afraid not, the value is added to the data offset. You could compare the data offset to another measurement made with the same SPL calibration.

Hi John, "undo t=0 changes" shifts raw REW measurements (not aligned by any means - as measured) to bring their first peak to t=0. Is this intended?

 

[John Mulcahy]

No, it doesn't do that. It has the same effect as the "Zero cumulative IR shift" button. The example measurement you attached has a small shift.

 

[serko70]

No, it doesn't do that. It has the same effect as the "Zero cumulative IR shift" button. The example measurement you attached has a small shift.

But that's the problem. The second measurement in the mdat was only just taken, untouched and it still comes with some cumulative IR shift in it which undo t=0 changes will remove.

 

[John Mulcahy]

True, it tracks some adjustments made during fractional sample interpolation, mostly for my benefit. I'll fix it in the next build.

Minor UI bug - there doesn't seem to be a vertical scroll slider for the SPL view. I need to right click and drag it around. There used to be a slider here:

I can also confirm that when taking measurements with an acoustic timing reference, sometimes the cumulative IR shift is non-zero, even though the measurement has not been touched. It's usually in the scale of ~0.3ms in my case.

I have windows 10, I have a slider. REW v5.40 beta 112.

You have turned the scrollbars off.

Oh wow, I scoured through the preferences section to make sure I wasn’t posting something dumb. Well here we are.
