Hi, when will the FIR filter processing option be available in REW?

Without RePhase
 
John has previously said that he does not intend to replicate the functionality of rePhase in REW. Maybe he's changed his mind.

John has provided some elegant maths solutions in REW m]which might get you to a FIR filter solution... However he has suggested thet REW is a measurement solution and not a FIR creation solution...

You might look at something like https://github.com/VilhoValittu/DecayCore/releases/tag/v1.0.0 or https://github.com/ObsessiveCompulsiveAudiophile/GSonic/releases... Or even https://github.com/xPoiler/XPDRC...

Cordially,

I have looked at XPDRC; unfortunately, it is not an independent measurement suite, it is a "crutch" for REW

I am familiar with the other utilities:

Gsonic lacks important settings, and the result cannot be controlled;

DecayCore looks promising, but as far as I understand, the author of this program is not an expert in the field of audio (he admitted to me that he does not understand how a spectrogram works and cannot integrate it into the application)
 
Just go use REW and rePhase. For a simple 2.1 setup, it's quite easy. Just remember that REW has no multichannel output, so if you want to test integration between your sub and speakers, you will need another piece of software (a convolver). You then need to pass REW's output through the convolver and to your speaker and sub. For 2.1 it's relatively painless (even fun) if you know what you are doing and where to look for side effects. But for 8 channels ... the tediousness multiplies very quickly. That's why some of us opt to pay for software like Acourate.
 
I have used REW and rePhase for a few years now... No big deal... DecayCore is open source... No reason you can't just write the code for that spectrogram you want so bad and stick a fork in it... :nerd:
