Is anybody familiar with the DRC software?

http://drc-fir.sourceforge.net/

I installed it from the Ubuntu Repo and exported the impulse response file from my room from REW as a stereo file as explained here:

https://www.audiosciencereview.com/foru ... 2.5/page-9

Afterwards I converted it to a raw file with sox as explained also in the link from above.

with

Code: Select all

drc --BCInFile=myinput.pcm --PSOutFile=filter_210320.pcm --TCOutFile="" /usr/share/drc/config/48.0\ kHz/normal-48.0.drc

a filter file should be generated but I always getting the error that my input file can't be opened. See below for the total output.

The file myiput.pcm exists and has a size of ~1 MB.

Code: Select all

$ drc --BCInFile=myinput.pcm --PSOutFile=filter_210320.pcm --TCOutFile="" /usr/share/drc/config/48.0\ kHz/normal-48.0.drc

Got it running:

The result is comparable with Sonarworks by the way!
