it seem the db average is not correct.

When you did the dB average you probably left the RMS average selected so it got included in the average.

ah yes,i do again, db average show correct sorry for post.

Hi, I would like to ask if there is an option to add an offset to measurement data in dBV, dBFS and dBr axis modes. Thanks in advance.

 

[John Mulcahy]

You can edit the voltage scaling on the Info window for the measurement:

dBFS levels can be changed by scaling the IR data using the option in the right click menu on the Impulse graph.

dBr is a relative axis setting and not affected by scalings or offsets.

Hi
I notice this new ESX EQ allow 31 band and low shelf for bass boost. before i did not find such a EQ in REW. It is the only i find with so many bands and low shelfs. but when i create a impulse response from the filters, i notice there is no LF filter add and is see in filter display. the LF is add in filter+target .
but how can i create a impulse response of filter+target ? . i test also the bass limit speaker as targettype in REW. this have same problem

normaly i use a peak filter manualy for the bass boost. because REW do bass boost only with LF shelf. a low shelf boost can cause earlier clipping and more distortion when all low frequency are boost.

I have no idea what you are talking about.

I have no idea what you are talking about.

the filters that are create from REW have no LF cutoff add at 40 hz 24 db. Edit: see also when press REW button "generate measurement from filters"

 

[John Mulcahy]

Why would they? EQ doesn't use low pass or high pass filters, they are parametric filters ( optionally with shelf filters) to bring the measurement onto the target. If you want a high pass add it manually.

@John Mulcahy Hi John, I installed the latest BETA 124 on a brand new Dell laptop running Windows 11 Home. I selected 4GB as the RAM during installation. After installation and restarting my laptop followed by opening REW, I saw the following crash reported. When the REW started after a reboot, I got 2 dialog boxes. One to load the UMIK-1 calibration file and another message saying I should right click on the graph for additional options. I could not close this right click message because the application wanted me to load the calibration file first. As soon as I selected the calibration file and then clicked OK to close the message about additional graph options, I was presented with this crash message.

Whatever happened there was inside the Java runtime rather than in REW. There might be more info in the diagnostic file you can generate from the help menu, if you attach that file or email it to the feedback address I'll take a look at it.

and for what is then this setting usefull ?

 

[John Mulcahy]

To set the target shape. The function of the EQ is to generate filters that bring the measurement to the target.
