NEW: Loudness
Trumpetguy:
I still struggle on how to understand and set reference volume (using Internal Volume). The first thing is my lack of understanding of what reference means in this context. From what I see onscreen is that when ref.vol = 100%, the volume slider is at 100% at 0.0dB attenuation. Vice versa, setting reference volume = 50%, attenuation of 0.0dB is reached when the volume slider is at 50% and cranking it all the way up to 100% gives a "positive attenuation" of +25dB. Does this mean my signal is way into the read, clipping >0dB range?
Secondly, what is the relation between Tools-optioons-Audio-reference level and Loudness?
Finally, what I would truly appreciate is a noob explanation of the things above and some method on how to determine the optimal ref level for me. ;D

I read about this interesting Loudness option and I noticed the following:
I set the 'Internal volume reference' to 80
I activated the Loudness option
When I adjust the volume to 100% there is no Loudness added in the Audiopath (just as expected)
When I bring the volume slider to 95% (+7.5) dB there is Loudness added
Where do I go wrong? I expected that Loudness should start from the 80% (+ 0.0 dB).
I have the 18.0.104 version.

I believe you found a bug with how the reference level is handled.
It will be fixed next build. Sorry for the trouble.

Using MC internal volume, increase the volume setting to the loudest you will listen at. It helps to use replay gain to keep this level consistent. Now use this volume setting as your "reference". As you turn down the volume, "loudness filtering" will be progressively added from this "reference" point.

Ok, thanks. This is what I did, and low and limited volume listening is actually way better than anytime before! I gather from another thread that there is a more scientific and correct way to do it, but that the gain/work ratio is too low to bother.
I am still not sure what happens when I turn volume above reference level. I have set ref.level=80%, and the volume slider is then at 0dB. Increasing further to 100%, the volume seems to have an extra +25dB added to it. Is that +25dB level actually 0dB (I do not know how to phrase it better)? It doesn't sound distorted at any level, so I am guessing the decibel scale is just different from what I am used to and referenced to the manually set ref.level rather than max output level. Right?
