I am a audiophile user of JRiver Media Center. I use custom made FIR filters for both cross over and room correction for music and movies. I do unfortunately not get this to work with DVDs.
I use convolution files in convolver (convolver.sourceforge.net). For music I use Convolver VST which I load in DSP Studio. For movies I use AC3Filter and Convolver Wrapper. (To get this working I have to deselect JRiver Bitrate monitor).Then I put a delay in FFDshow video decoder for sound/picture sync.
The correction files are being created with Audiolense (
www.audiolense.no). It is also possible to create correction files with DRC (
http://drc-fir.sourceforge.net/)
My problem in MC is that it is not possible to select additional audio filters for DVDs. I therefore use another program to watch DVDs. This is unfortunate since I would like to use J River for all kinds of files.
This is how they do it in Zoom Player:
So what I wish to see in J River is an option to select additional filters also for DVDs.
