New speaker DSP in Media Center 14.0.127 [Room Correction]

<< < (5/11) > >>

mojave:
I found by using the mute and/or solo button that the Room Correction DSP only works when Playback Method is set to Automatic. If I add any DirectShow filters then it does not work. Also, it does not work for movies (I tried with ripped DVD's and MKV's). I have used AC3Filter for movies, but I found out yesterday that I can use AC3Filter with audio files, too. I only tried it with FLAC and APE files, but it worked great for distance settings, delay, crossover, and speaker output configuration (2.1, 4.1, etc). This is what MC's Room Correction needs to be like. In order to use AC3Filter with audio files, in Playback Method I selected JRiver Audio Engine (using DirectShow filter). I then checked AC3Filter.

Audionut:
Just another vote for native convolver support in mc!!! I use it for room acoustic correction based on the measured response of the system in my room at the listening position, it is a superb feature for crazy audiophiles like me  ::) and hopefully others too.
Great that .VST support is there already, but the integration with the vst plugin and mc is not ideal of course. It is brilliant that it is there, but a native one could be so much better:

A must would be to have a default filter file loaded and enabled for standard playback. A nice to have option would be remote commands to switch the convolver filters like presets (great to compare different target responses).

Thanks!

DSP for movies, DVD, television

I have a feeling this is coming.  Maybe soon.


Convolver

Perhaps someone who is a fan of convolver could help us get something set up in a way that sounds good.

I spent some more time tonight playing with convolution.  I was using a Sennheiser HD600 headphones, but have also used it with my surround sound theater system.  I haven't found anything that seems really interesting.

It feels like an overly complicated way of doing equalization.  Speaker reverb correction might also be neat, although it seems like it's easy to do more harm than good with heavy processing for this.

Thanks for any tips.

Yeah I use it also like that for room correction by measuring the response at the listening position with a decent calibrated mic.

If you have not tried the vst plugin route you should it works 100% ok with mc. You can also use the open source directx drc convolver with mc. The only issue with the dx convolver is that you have to reenable the settings each time you start mc.

Audionut:
Yes, I use a VST plugin which works very well, but so far every plug in I used had one or the other issue in terms of working without needing some sort of work around. Like you mention, reenabling the setting, or  my current one keeps the default setting, but the automatic level correction (convolution is always reduced in output volume over original signal) does not work when I start mc new on my dedicated PC. I need to enter the DSP Plugin, see the user interface, switch a filter for it to be picked up. Of course I can do this each time, but it is just annoying to have to remember and do it every single day.

Since I have tried so many convolution plugins I have the feeling the only way to get this to work smoothly without manual interaction would be to have the whole process in the hands of one developer, ideally inside mc...
