Exporting from REW to Equalizer APO?

[flexy123]

I am a big fan of Equalizer APO/Peace which I use for a long time. Only a few days ago I started with REW as well.

I can play with REW, and for example use the "Audyssey One Evo" script (for Audyssey calibration on my AVR), and among many things that the EVO script does, it enables me loading an Audyssey .ady file into REW (since it extracts the measurements), and later on again exporting a newly optimized .ady file that I can load into the AVR.

Now, my goal would be to export everything from REW to Equalizer APO. Basically, that the final Audyssey calibration is running on PC on E.APO, rather than in the AVR.

What do I need to export? I understand there is not only filter settings, but possibly also IR and other stuff? I am not sure whether simply exporting filters (and then loading them into Equalizer APO) is all I need to do? Anyone an idea?

When I created DSP files that included phase correction and were created through REW and rePhase I had to export the filters as convolver .wav files. (One for each sample rate I could potentially use and in my case for each channel as well.) However, while I created the general EQ portion of the file through REW, I created to finalized .wav file with phase correction through rePhase. I'm not sure if it is possible to create them from REW. I use those files with ROON as my DSP program.

I followed the instructions here:

A Guide to Advanced Room Correction with REW and RePhase using Convolution filters

I am getting some complaints that this tutorial is too long so I am adding a 10-step quick guide for those of you who want to use Roon convolution filters for Dirac level speaker & room correction in both frequency and the time domain: With FDW ticked in preferences in REW, take two...

That's my personal experience. Sorry if this doesn't answer your question exactly. I'm sure others can add information and recommendations.

But if we are talking the general EQ, all you need to do from REW is export your filter by clicking "Export filter settings as text" near the bottom of this menu. I highly recommend the PEACE GUI for Equalizer APO as it makes it easy to switch between different EQ settings and different outputs.

I've read that it is possible to load convolver files onto Equalizer APO (though I myself have not tried) but perhaps you need to use rePhase if you want to include phase correction. In the meantime see what happens if you try "File - Export - Export filters impulse response as WAV."

If you aren't worried about correcting phase you can just export the filters as .txt and load them directly in EQAPO. I would actually recommend doing the filters as text and then only do phase correction via WAV, since frequency resolution is limited in low frequencies using FIR.

You can import your REW EQ into Equalizer APO as PEQ, variable band GEQ (1000+ points if necessary), or as .WAV convolution file.

.ADY won't work.

I'm working with the REW and I want to EQ with either WiiM or APO-EQ.
- The WiiM streamers offer: peak, low-shelf, high-shelf
- The APO EQ is a lot more flexible, offering peak, low-shelf, high-shelf, low-pass, high-pass, etc.
Probably a stupid question - at least at first sight:
--> Which of the equalizers that REW offers to export to should I use?

Currently I use the "Generic, Configurable PEQ", which works nice, but it restricts me to peaking filters. If I could at least use high-shelf and low-shelf (even just manually without Auto-EQ capability) it would be helpful.

And yes, the speakers I'm currently EQ-ing are flawed - the developer quite obviously did not know about the baffle-step ...

A workaround would be to measure with WiiM / APO-EQ shelf- filters in place and optimized, then evaluate the other EQs with REW and add these to the existing APO-EQ config.
But this sounds like a nasty procedure that eventually even ends up with iterations. I would rather measure the speakers as they are and do the equalization in a completely separate step.
Sure, a final "verify" measurement is mandatory.

My next question is hidden in the configuration of the "Generic, Configurable PEQ": Which definition of "Q" conformes with the peaking filter of the APO-EQ?

For the WiiM the correct Q definition is "RBJ Q (half gain) the WiiM support answered.
--> What's the definition to choose for the Equalizer-APO?
