Ok, back to B20 processing then. I'll make the "S" effect configurable.

I found the cause of the visual bug - will be fixed in the next beta.

VST plugin issue still exists.

The problem doesn't seem to be that the highs are too loud - the Orban has higher (w.r.t. BETA20 equally loud) highs. Except for that, the "Allow louder highs" slider is actually controlling an extra filter on the highs based on a much wider band (so yes, it does help - but it's already there).

The real issue is within Loudness. Highs - with pre-emphasis - come out at 'extremely' high levels (they are boosted by 10 dB for 50 us pre-emphasis, and even more for 75 us). Loudness then boosts the entire sound by another upto 12 dB, which means that already loud S sounds can in worst case get a boost of over 20 dB - and that can be 20 dB above the level where the waveform is already reaching the limits. Loudness can handle a lot, but it's not omnipotent - so I can either reduce the highs a lot during spikes (which results in the 'very soft S sounds' effect that I hear on lots of FM stations, which lacks punch), or accept some volume loss at lower frequencies (which gets really annoying if it drops too much). Now in BETA20 I used another alternative: I'm now allowing a bit (not much) of extra distortion in the low frequencies, so they are not pushed down as much anymore. This should make room for loud highs without much volume drops in the rest of the sound.

SOMEHOW I MISSED AN IMPORTANT CHANGE, THE SOUND QUALITY OF BETA20 IS NOT RESTORED! BUILDING AGAIN NOW, WILL POST NEW VERSION TOMORROW.


- S handling configurable (0% = old style, 100% = BETA20 stype, 200% = even stronger).
- GUI issue fixed.

Ok, this time the "S" processing follows the new settings. This means:
- Max highs burst at 100% = equal to BETA20
- Max highs burst at 0% = equal to BETA19, EXCEPT that the change between BETA20 and BETA21 is now made in favour of the the BETA20 sound. So I expect the sound with Max highs burst at 0% to be slightly better than that of BETA19, with the same highs level.
- Max highs burst above 100% = even more highs.

1. Sure - it shouldn't crash or anything, and I think the sound is at least as good as that of v5.02.
2. The effect is small, and unless you boost the highs by using the equalizer (which I did in the settings I posted earlier to mimic the Orban sound) you probably won't notice anything at all.

With this setting at 0%, it performs worse than the Orban, at 100% it's equal - but as I mentioned the effect is really subtle.

Band contains all audio upto 100 Hz, dropping to nothing above 200 Hz.

Is that bass distortion (ie. "S" with bass present causes the "S" to vibrate), or do you hear frequencies that shouldn't be there?
