I'll have to bone up on the technical knowledge however.

The basic technical know-how required is

- How to use REW to make a measurement and export it as a WAV file in float32 format (I always export left and right as a stereo file, assuming a stereo setup). There are lots of tutorials on how to use REW for measurements. (I would ignore the scripts that come with drc-fir for measurement.)

- How to use sox to convert to the raw binaries that DRC-FIR uses. If you have a stereo float32 WAV file exported from REW called impulse.wav

sox impulse.wav -c 1 -t f32 impulse-l.pcm remix 1
sox impulse.wav -c 1 -t f32 impulse-r.pcm remix 2

Will create raw left and right impulse files. How to use these files to generate correction files is described on the drc-fir website.

- How to get the drc-fir correction files into a format appropriate for your convolution software and configure that software.

  SOX doesn't sound best to me.

    I suppose that's a joke, but this is the Asylum...
    
    Sox is just used here to split a file into left and right channel parts and save as a different format. It's the same exact PCM data, though).

      In fact I did look into it briefly and decided to postpone further action due to the fact I don't understand how to install and use DRC or sox. But yes, I might get around to it.

    ...he asked for a specific solution.
    As usual, you rarely ever respond with a solution, but always your knee jerk opinion. That's easy but not what was asked for.

      At least I don't waste resources by just posting pretty pictures.
      
      You have your opinions, I have mine.

        My posted pictures don't "waste resources" on the Asylum, they reside with my internet domain registrar and web hosting service..... not on the Asylum. I have explained this before but you can't seem to grasp the concept.

  SOX2 doesn't sound best to me.

    The software I was recommending was DRC-FIR, which creates digital room correction filters and has nothing to do with sox.
