Some things i don't understand.
This is web preset. It's really important or i would not mark it like that. Yes you can play it on FM but for sure you will not be loudness-war winner. Also some other clipper settings need to be adjusted to better fit for FM. (streaming require limiting and FM is ok with clipping!). FOr howm listening only your ear is important.
Also i don't understand how you have good FM signal with pilot and rds at 96kHz!?
If you halve that, that is 48kHz and that's only enough for SSB MPX signal but for sure not for RDS. (57kHz).
I started to use PowerBass in last few versions to squeeze more bass into audio. However peek level is NOT changed!
You can try yourself, play 60Hz sine tone, for example, lower clipper to 0dB and measure peek level. Then turn off power bass - there will be almost no difference, in case of 40Hz with power bass it will be even lower peek level
Ok testing track "Indila - Ego"
Test is to measure avareage level at all bands - Original vs processed.
I took first bass kicks from track (wich because low BPM and slow attack ion first band gives loudest processed bass) and played into loop. Lowered clipper to -1.51dB to match ~ input and output bass level.
Here is source - 250 avarage level
And here same but processed
As you can see everything is prety much similar level
As usual, I always want to preserve bass.
OK - so from the beginning
1. I know it's a web preset
In the FM part of one of my previous posts I mentioned old version of Unvail.
2. My audio codecs works like this:
when I set Sample Rate at ST (Sound Card section) it has effect on the *quality* of sound but not on stereo or RDS coding (I know it sounds strange but that's the way it works)
http://i.imgur.com/xG1SYVb.jpg. The crucial part is to set Speaker setting to 192 kHz (or VAC) in the system control panel (not ST) - it works that way on my Win7 x64 and all ALC codecs I have. So even though the ST sample rate is set 96 kHz (in the screen above), the real output sample rate is 192 kHz. When I set 192 kHz in ST, my CPU is melting and I get serious stuttering and buffer loss. When I set it to 48 kHz I get resampling artifacts. When I set it to 44.1 - The sound is good but I get some noise in the pilot area - strange and extremely nonintuitive, but that's the way it works for my system configuration with Realteks and Win7.
3. Do this graphs show L-R? (BTW I like the way you support or defend your theses)These graphs should represent L-R signal in order to notice what I meant. Anyway, even on them you can see that this processed sound has slightly different texture that affects (my) perceived loudness of the bass L-R parts - notice the 50-80Hz area boost in the processed sound (it is more audible than sub-50 Hz part, due to human ear frequency response). But what I really meant is that when you listen to variable material using this preset, there are some tracks that clearly stick out (but not as dramatically as you may have thought) due to their bass L-R content. And that's the way they sound unprocessed too, in comparison with other tracks.
I have always been trying to mitigate these differences to make audition more smooth. Also, few years back I usually processed bass all the way in mono to avoid such phenomenon (which is sounds pretty bad in lo-bitrate scenario). Then you could make things wider without the risk that you get awful mumbling sound in the L-R part due to very low bitrate (since in these scenarios usually middle-side techniques are used for stereo reproduction, you have some headroom for codec when you cut out the bass from the sides). That's just my opinion of course.
And last but not least, I already mentioned numerous times that this preset is actually my favourite, cause it sounds good and gentle on most of the material I've tested
No argue on that! Actually no argue at all, just discussion, right?

I just hate W7 when it comes to audio.
