121. Automatic "Ignore high frequencies above" frequency selection. 19200 for composite, maximum lowpass freq + something for others.

What this suppose to mean ?
For FM we cannot set it below 19200 ?
Excuse me but it works superb at 16200 now even with all composite signal.

Why auto , when we can slide it ? Disable of the slider now ?
19200 is only needed for Composite with Stokkemask, I will fix this (coming beta will use 19200 for all Composite Clipper presets). You can still overrule the 'auto' value. This is just there to simplify things. Currently 19000 is hard coded, while in many cases 17000 would work, and in some 19000 is too low.

7.84 BETA009

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 84-009.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 84-009.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 84-009.dll

CHANGES / BUSY / WAITING FOR FEEDBACK
- Check if True Bass generates too low subs and if needed add HPF. -> Non-phase linear HPF is done before True Bass, the True Bass signal itself needs to be highpass filtered separately in this case! -> First improvement done, waiting for feedback.
121. Automatic "Ignore high frequencies above" frequency selection. 19200 for composite, maximum lowpass freq + something for others. --> BAD, should be 19200 for Composite with Stokkemask, otherwise normal calculation! So check Stokkemask + Composite instead of just Composite.

PREVIOUS CHANGES:
- Fix PNR for VST plugins (at least partial fix).
- Add backup sound card support (sound card 1 switches to 2 after some silence).
- Bug fix: Non-phase linear de-emphasis was killing BS412.
- Show a warning when someone enables non-phase linear de-emphasis. Among others about peaks!
- Add function to Get parameter values for Generic plugin version
- Added 8 times oversampled non-phase linear Butterworth de-emphasis to match some hardware unit's pre-emphasis behavior.
- Some filter to clean up ringing artifacts when using steep bandpass filters contained an error which caused some clicking effects, mainly in low bass (This bug has probably been there since version 5.00!).
- BS412 didn't calculate the level correctly when using left/right output instead of MPX output, and when 'Pre-emphasized output' was not enabled. Fixed. This can have a big effect!

BUSY:
- Adding option to share band split/merge between multiple filters (starting with 2 MB's). This should reduce the CPU load a bit, but so far that doesn't really seem to be the case (14.5% to 14.3%).

TODO:
- 2-band AGC is heavier than 2 Multibands in Analog mode (ow wait, that's splitting only, without compression!). That's crazy.
- Cleanup filter for artifacts is heavy too.
- Add new presets

7.84 BETA010

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 84-010.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 84-010.exe
Windows VST 32 bit: ----://www.stereotool.com/download/vst_stereo_ ... 84-010.dll N/A

CHANGES:
- Made HPF filter for True Bass non-phase linear as well if non-phase linear HPF if used. Note: This does mean that some cancellation can occur above the filter frequency!

- Fix GUI-related hiccups in VST in Audition reported by Ted - for BETA016 he also reported now that the audio is different when loading via VST host!
- Fix hiccups in stand alone version at 44.1 kHz reported by Benny
- Waiting for feedback about True Bass sub-bass from Bob Hawkins

TODO:
- GUI: Disable Composite Limiter slider when Hard Limit is disabled.
- Fix ASIO support: Only claim the channels that are actually in use, and allow using more than 6.
- ASIO bufferChanged call watchdog doesn't work (and probably never has).
- Add new presets
- O Skin


PERFORMANCE MEASUREMENT RESULTS (values shown in GUI, so on one core):
- Nothing: 0.1% With Overhead (top CPU load indicator): 0.6%
- AGC 1 band: 0.4%
- AGC 2bands: 1.1%
- AGC 3bands: 1.4% --> So 0.3% per band, 0.4% extra when switching on multiple bands. That 0.4% must be the cleanup filter.
- Stereo Boost: 1.6%
- ACR Stereo: 0.6%
- Stereo Image: 0.3%
- AZIMUTH: 0.4%
- ND 9 bands: 2.1%/2.2%
- Noise Gate: 1.7%
- Declipper: 2.3%
- Phase Rotation: 0.2%
- Phase Delay: 0.3%
- True Bass 2 bands: 1.6%
- MB1 9 bands digital: 4.2%
- MB1 9 bands analog: 2.5% --> Weird, uses more than ND!!! That's unexpected since ND is based on Digital mode.
- MB1+2 9 band analog combined: 4.8%
- MB1+2 9 band analog split: 4.8%
- MB2 9 bands analog: 2.9% (raar)
- Bass Boost: 0.8%
- Singleband digital: 1.0%
- Singleband analog: 0.6%
- Advanced Clipper: 3.7% (met de-esser?)
- FM RDS/Stereo: 0.4%
- Advanced Clipper: 3.5%
- FM + Advanced Clipper: 3.7%
- FM + Advanced Clipper + Pre-emphasis: 3.7%
- FM + Advanced Clipper + Pre-emphasis + Stereo + RDS: 3.7%
- Same with Composite Clipper: 10.1%
- Strictness at 5 instead of 8: 7.5%
- With Stokkemask: 13.3%

I think that "FM composite limiter override" option is not working at all. It just enable the indicator at 101% (it should be like this) but nothing more. No difference , no indicator moving, just enabled indicator and that`s all.

I`m still with beta 6 but i don`t see any changes there , so this must be there since many betas/versions. Talking about the Stand alone, but it`s good to be checked in other versions.

The indicator does more here, I'm guessing that you found some combination of settings that doesn't work. So, more details please!

Are we tallking for same thing ?
If so, then download the settings and try. If still work on your side , i`ll make a video to show you.
