How to upload filter curve file from REW (Room EQ Wizard)

I would like to upload the set of filters I developed using REW (Room EQ Wizard). I suppose the AU NBand Equalizer is the best option among the effects. Are there any instructions available? As a fallback I can re-enter all the filters manually, but how to translate Q to Width? Any other tips are very welcome!


Hello MediumRare - I had the same question as you … until I read a few replies on this forum. I have opted for a different approach: export the filters from REW as a WAV file, and then import this WAV file into a convolver plugin in Audirvana (I have installed LA Convolver, free for MAC).

Is anybody else doing room correction via Audirvana/MacOS?

Yep I am, MediumRare. I also have REW. Probably the easiest way to transfer the REW settings to the AUNBand plugin is to enter them manually. Here’s a calculator to convert Q to width and width to Q :

It works a treat!

Recent 5.20 beta versions of REW support AU N-Band EQ directly, no need to convert any values anymore. They can be entered as saved to the text file.

Hi Dan - how do you get LA Convolver to work in Audirvana? I also have it installed but it doesn’t show up as a plugin in Audirvana (or AU Lab for that matter).

hi Frank, it may be a case of restarting Av so it takes the plugin into account. Have you tried this ? else, the process is just to unzip the plugin in the appropriate folder, which i suppose you have done already?

Yep done all that. Neither Audirvana, AU Lab or Audacity are recognising it, though. Also tried restarting my Mac. Ah well, didn’t cost me anything so I can’t complain!
