Download the InguzTools package, and unzip into any convenient directory.
Install DRC. Make sure drc.exe, various .drc files, and your target files (flat.txt, ecm8000.txt, bk-3-spline.txt, etc) are all in the same folder as ImpulsePrep.
Linux users: build DRC from source. Instructions here. Also be sure Mono is installed (per the DSP instructions).
Edit .drc files for microphone (e.g. MCPointsFile=ecm8000.txt) and target curve (e.g. PSPointsFile=bk-3-spline.txt).
Open a command prompt, and type
ImpulsePrep /L left.wav /R right.wav >prep.log
For each .drc file, you should have a new .wav file (so for “normal.drc”, you should find “normal.wav”) which is the correction filter. If this .wav file wasn’t created, you should read the file “prep.log” to determine whether DRC failed.
Also, a slight variant of the same filter is created, (”normal_direct.wav”) with overall target frequency response compensated for a flat direct sound. Depending on your loudspeakers and listening environment, you may find that this sounds more “live” than the standard filter.
Copy these correction WAV files, and NoCorrection.wav to the InguzEQ/Impulses folder where they can be selected as room-correction filters.
Finally, some test files are created (”normal_TestConvolution.wav” and “normal_direct_TestConvolution.wav”). These are the result of processing the measured impulse response with the room correction filters — for those inclined to analyze their uncorrected and corrected impulse responses.
