RE: I will check further into DRC

Posted by Daverz on April 5, 2021 at 16:06:57:
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.
