A simple question:
Comparing your SSm4 with my IO2.3.16K, what Post Amp compensation value(s) do you use ?
What is built in with the preset, so with mine it is 0.99 and with yours it is 0.96. Everything else incoming and outgoing is exactly the same.
So, what do you do except loading the presets ?
You have to compensate the (extreme) loudness difference !
If you don't compensate it, it is more or less a waste of time, because you compare apples and oranges.
Ok, you say that my IO preset hurts your ears (2.8K and 1.4K bands).
Of course if you calibrate the output volume for your Supersonic preset (and I know that you prefer to use headphones) it is not a surprise that the simple loading of my IO preset is hurting your ears (this would hurt my ears too).
For me (using loudness compensation) it is more that your SSm4 preset and its overemphasized 5.5K, 8K and 11K energy hurts my ears.
And this frequency range from 4K to 11.5K is known as the most problematic (excess sibiliant sounds, hihats, cymbals, etc.). for mastering.
Different people have different needs (and different ears).
So, everyone has the freedom to create or adjust presets for individual taste.
I still do not like the way yours process (emphasize) especially hihats and snares (this hurts my ears).
I use to compare presets by adjusting (lowering) post amp settings to match the original unprocessed loudness.
And doing this I have the (subjective) impression, that your preset creates overall a more artificial spectral signature than my preset (relative to modern mastered CDs).
And that is the most important difference between your preset and most other user presets on the one side and Bojcha's Addiction v11 on the other side.
Addiction v11 keeps the resulting spectral output balance very close to the original structure.
It is very good for most modern type of music.
The only disadvantage it has (for me !), that its processing is too neutral for old music.
Maybe, I am trying the impossible with my preset.
But I like it - ok.
You (and others) don't like it - ok !
Whatever - if you don't like my IO preset than stop to waste your time and ignore it.
But for your own preset development it would also help to use an exact (as possible) Post Amp loudness compensation (reduce Post Amp and save this to a new preset) to compare your preset with the unprocessed spectral signature (it might be necessary to adjust it a little bit from one track to another).
The difference is pretty much all Multiband. You can get my preset to sound similar to what you appear to like by changing it to LIMIT. That's the normal difference between limit and compress... There are a few finer details that make a difference still, like the upspeeds and EQ settings, and then a few differences in loudness, but the majority of difference is just limit vs. compress...
Can't you hear the noise ?
Load my IO 2.3.16K preset and turn the Noise Gate off (or use your settings) !
Noise Gate is very important (and of course the AGC -12 dB RMS target output).
