BETA620-028:
Ok, for those of you reading only this thread who think "huh, where are versions 022-027?": There were some changes made due to the Sound Processing Freak Day. And they are described (and beta's available) in that thread.
The summary: The de-esser got replaced by something that works much better.
Notes from previous BETA (about declipper):
Quote:
Note that declipping uses a lot of CPU processing power (I'll make that configurable later).
The filter can be switched on or off at the right of the input level slider.
The 'maximum peak restore' slider does not work yet (dunny why, will check).
IMPORTANT: Set the 'clipping detection' level low enough such that ALL the clipped samples are recognized as being clipped (for a CD that's easy, 32767 should suffice, but for an MP3 you'll need to set it a bit - even upto 10%! - lower).
Hint: You can see that the declipping filter is working by comparing the input and output levels with NO other processing enabled.
IMPORTANT: Declipping can currently NOT be combined with non-phase linear highpass filtering!!!
Samples that are incorrectly seen as not-clipped (level set too high) can have a big effect on the audio.
Samples that are incorrectly seen as clipped (lever set too low) make things harder because basically Stereo Tool must treat them as if they are clipped at the selected level. So basically you add extra clipping before removing it.
Later I'll add some code for dynamic clipping detection. (Something with a histogram I guess).

TODO:
- Fix loading changed multiband frequencies
- Add buffer and filter for SCA output (SCA1 ok, SCA2 ok)
- Finish AGC improvement - make mono value configurable (replace checkbox by slider) 1 hour --> NO, not needed - anything else needed? -> NO
- Fix Punch
- Check what to do with new filters (such as bass AGC) - keep them, remove them, change them? --> KEEP
- Save new BASS_AGC setting in VST mode
- Loudness: Annoying cracking sound in bass. Slightly present in 5.00, worse in 6.00, maybe even worse in 6.10. Only when bass is too loud. Much worse than in Final Limiter (at same input level!) - so this clearly indicates a bug. Most likely cause: The filter that was added to remove bass artifacts....... 
- No, it's the louder bass. But it can be fixed by changing some settings. Default settings updated, and behavior for 'not Very strict' improved. Also Deep bass boost and Very deep bass protection are enabled for latency 512 now.
- Finish declipping filter.
- Finish new de-essing filter (check what to do with the settings, remove at least some!)
- Add lowpass filter for stereo signal (will cause a lot of extra latency!) - it might be possible to avoid this latency using a Hilbert transform
- Update presets? (BASS_AGC etc.)
- Change version number
1 hour
- Release

i hope this cuts everything under 20 hz on the mpx signal becuse if heavy processing ocures .. some DC is generated whatever i do:)
