Please add the option to do a custom (stereo) downmix, i.e. the possibility to manipulate a channels volume and apply a filters to channels before dowmixing like for example to the LFE as one might do for a separate subwoofer but in this case for the bass that gets donwmixed to stereo.
This has always bothered me since many movies and series on streaming platforms but also on physical media have their bass turned down and cut off too high and it would be nice to have a way too compensate for that if one has a system capable of reproducing those low frequencies.

If that is already possible, please enlighten me because in that case I seem to be too stupid to figure it out but if I got it right, the downmix sadly always happens before anything else...


Thanks already in advance!

Parametric Equalizer can be used to do 5.1 downmixing if you don't want to use JRSS.

Thanks for the quick reply!

Okay, so in the JRSS settings choose 5.1 and not 2.0 and do the whole dowmix manually with the ParamEq.
Could you point me to a resource telling me the standard attenuations for a 5.1 (and maybe also 7.1) downmix to 2.0/stereo that includes the LFE channel and doesn't discard it, so basically the internal JRSS parameters?

Thanks again!

I just tried to do the downmix from 5.1/7.1 to 2.0 manually via Parametric Equalizer but with no luck since if I choose 2 channels as output than all other channels are discarded before Param Eq and if I choose 5.1 channels as output than presumably the channels all reach Param Eq but mixing there does not bring anything since the output is set to 5.1 which my stereo DAC of course cannot handle.

In other words from my POV what would be needed is to have all 5.1 channels internally available inside JRiver/Param Eq but than have the output only be 2/stereo channels which is the output format needed for stereo DAC's.

(From browsing the forum a bit this seems like a topic that gets brought up every now and then...but I could not find a solution, or did I miss it?)

You're right that if you pick two channel output that's all that will be left by the time Parametric Equalizer runs. The format is handled first.

So you would need to do more channel output, then mix to two channels at the end.

It might make a nice enhancement some day to work around this, but it's unfortunately pretty complicated.

Thanks.
