Urs Posted January 29, 2021 Share Posted January 29, 2021 I am using the latest Audiolense XO version. I have passive speakers (2.0 Stereo). I am using a miniDSP UMIK2 microphone. Speaker measurement went well. For filter measurement I used the default (True Time Domain). I experimented with several target curves and ended up with one which I really like. I created appropriate filters: a set of *.cfg and *.wav files for J.River as well as the corresponding *.zip file for using in Roon. This means the convolution filter in J.River and the convolution filter in Roon are based on the same measurement, filter (TTD) and target, but... now comes my issue: Playing with J.River: activating the convolution filter is a significant improvement compared to not using DRC. Playing with Roon: activating the convolution filter sounds dull and worse compared to not using DRC. Additional info: In J.River, when using the convolution filter, I have to increase the volume for ca. 10dB compared to not using DRC. This is expected and not a problem. In Roon, I have to increase the volume for only ca. 3 dB compared to not using DRC. My observations are valid for all sample rates (44.1, 88.2, 96,...) The situation in Roon does not improve if I enable headroom management and adjust headroom by a few dB, so that any clipping is avoided. I did ask this question in the Audiolense forum. It was confirmed taht Audiolense creates exactly the same correction for both players. So there must be something going on in Roon... All suggestions are welcome. Of course I could ask the same question in the Roon forum, but I wanted to try it here first. Link to comment

I read the post. User Omid at avnirvana is right. I also checked the correct syntax here: http://convolver.sourceforge.net/configegs.html I edited my *.cfg file accordingly. It works now as expected, i.e. same behaviour/improvement in Roon as I have in J.River. @asdf1000Thank you very much. 🙂 asdf1000 1 Link to comment
