I'm going to try creating 1 or 2 of the RME curves in roon and see how I feel when I switch them in. +10 dB lift at each end is much more than I expected, working out the 0db setting will be interesting.
This is a really intelligent adjustment.If, like me, you have inefficient speakers in a large room you have to turn up volume quite a bit and the loudness function then assumes that you are listening at loud levels, which you are not really doing. So I raised the reference level at which the loudness function cuts in, and also the amount of compensation (I only did this for the bass frequencies).
Roon's explanation is this:I see no reason that if RME can do it roon cannot do it easier with it's full Windows app, and interface.
Roon's explanation is this:
"The main barrier to doing this in Roon is that Roon does not have an internal volume control–in our architecture, volume is always endpoint based. So while you could easily do a perceptual EQ (even in PEQ/Convolution features today), getting it to change with volume would be a bit trickier."
There's a thread on it in their forum. I understand their reasoning
I don't understand that, they do have an internal volume control, it can control fixed output devices using digital attenuation, and with quite a few endpoints it can control that devices internal volume.Roon's explanation is this:

I don't have Roon, but the way I do it via JRiver is as follows:
In a multizone home audio system, each zone also has its own dedicated DAC (I did that, anyhows). So then I can set my levels and loudness settings independently between speaker systems/zones. I have different Reference Volume and Level Calibration settings for each zone. Volume is adjusted in the remote app and zones can be switched/linked together as needed. Loudness DSP and EQ between zones are basically not the same, but their default volume calibration level is very close. So if I set 80% volume in my home theatre, it will sound pretty much close to the same level at 80% in my family room. The manual volume knob/control for each system is set at max/default locally in their position. Levels is controlled centrally and digitally in the HTPC server itself via remote.
Applying the curve is wrong. Only bass region can be used. You have the gain in 3khz in nature, if you subtract it, it's wrong and unnatural.
Reproduction has rule of course. If a wall is flat, you don't carve it to suit your hand to feel flat. Simple.Hi, John, do you mean to say the treble? Ahem, subjectively here, it does not sound wrong or unnatural to my ears at all. Although, I do admit, it would be nice if we could adjust JRIver's algorithm manually -- e.g. disable treble compensation curve, reduce or increase bass compensation, and the like... However, overall, to me the balance is good enough. If you watched the video, you will know that the research on loudness isn't as polished as some proponents might suggest. There is no hard and fast rule that says treble should never be compensated, otherwise it would sound wrong.
Reproduction has rule of course. If a wall is flat, you don't carve it to suit your hand to feel flat. Simple.
If you prefer the sound of recessed 3khz range then fine you like it. But it doesn't reproduce the sound as recorded.
I don't have issue with this one.

You can take this picture as reference in the future. To everyone else, do not use the raw equal loudness contour but the relative loudness contour.

You can add as many zones as you want/need. Link and unlink zones and/or switch between zones.

Change DAC device for each zone... for exampe, I have two DACs in my Family Room and I can choose whichever one I want to use from here.
Each zone's volume, Loudness DSP vol. reference and EQ is independent from the others:

The more devices you have running in parallel takes a toll on the PC processor quite a bit -- with all the extra DSP running per zone, though -- so you need a fairly fast/powerful PC.

The legend explained everything i think.Can you explain what the relative loudness contour refers to?
