Title: Feature request: Digital room correction
Post by: harryharry on January 29, 2010, 06:11:09 pm

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.


I also have another request:

To get convolver to work with more than 2 channels I select for example 8 (7.1) channels under "output format" in DSP Studio and can then use 4 channels for cross over for each speaker.
In DSP Studio would it be possible to have more than 8 (7.1) channels? This way it is possible to use more than 8 channels (multi channel speakers setup) for digital cross over together with convolver VST.

I want to do similar things.
I  use Convolver but as direkt show filter version,as there is native support in dsp-studio for that.
I calculate my filters using acourate software.

Hi Harry,

Would be great to get this in MC14.

How did you generate your FIR data btw? I have a calibrated Dayton mic and RoomEQ Wizard but haven't had much time to do any analysis.

Any room treatments? We still even need curtains in here  ;D But it is a good room, dimension-wise.

I use Audiolense to generate the FIR filters.

I have several listening rooms. My cinema is treated with absorbers and diffusors on all walls and roof.

I guess this was fixed in 14.0.141 so you can play also DVDs in MC now, Harry? I'm also looking to correct my room with Audiolense. Are you outputting the sound using the analog outputs from your soundcard? I'm looking to output multichannel LPCM via HDMI to my receiver, since I don't have an expensive/audiophile soundcard (yet).
