Brian, you are not right .
Till now every installer is "new" for people . And when you click it first is blocked and then Cloud retries info on server , not vise versa . This is for first time on my side , so Installer program is making something that looks like virus (maybe it's a new version updated). This is the problem. Don't worry, i perfectly know that there is no any virus .

The GUI is still absolutely miserable to use when you scroll the preset list. Oh, and yeah, this version is worse for that one aspect. It is not a function that people do a whole lot, but it is kinda one of those "why in the world does just this one thing cause the whole program to freak out" questions. Enabling the Advanced Clipper does not even generate the kind of load that scrolling the preset list does.
Other actions in the GUI do not generate such hammering, so whatever you're doing with the preset list should be checked and corrected or reverted. Between 7.43 beta 5 and beta 9.
That's old problem. Hans's GUI workd just like that. You have it with "preset list" and i usually have with EQ graphs.
Even mouse hovering over gui makes big cpu load.

Hans are there any changes made in version 7.45 that make it impossible to work on that pc?

Point is that when the presets list is open and things are moving in the background, it needs to redraw both the background and the preset list all the time. Drawing the preset list includes writing all the texts in it, and displaying texts is slow/heavy.

@Bojcha: Are the EQ graphs still heavy? I thought I had fixed (or at least greatly improved) that a while ago...

I remember when you improve it. But it still makes problems. As i said, when CPU is on edge even hovering over any place in gui makes stuttering. I asked for option to turn off scope and i am now asking same for FM graph.

There must be way to fully avoid that.

BETA745-004:

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 45-005.exe
WINAMP DSP: http://www.stereotool.com/download/dsp_ ... 45-005.exe
VST: BUILDING


CHANGES:
- Added L+R loudness jump detection - on L+R loudness jumps we can adjust the L-R level at a MUCH higher speed without causing noticeable effects. Which helps to create a much more constant stereo image.

This is a bit difficult to set up (default settings MIGHT be ok, but better settings might be possible); I might try to simplify it later or even remove parts of it completely.

Here's what I did:
- There's a new panel for Punch Detection
- It contains an attack and release setting which behave as a normal (extremely simple) attack and release on the signal.
- The next thing that happens is that the amount of attack that occurs is added up, and reduced again. The reduction speed is set by Peak Detection Drop.
- Relative Speedup determines how much faster all the settings under Response Speeds (except Peak Follow) are working relative to the value found in the previous step (Peak Detection with Drop.).
- This would be completely impossible to configure. But the next two sliders will help here. If you set Volume effect strength to 100%, stereo enhancement will only occur at a Punch peak. Volume effect can be used to adjust the relative level (compared to the Peak Detection level). Note: With a slow Peak Detection Drop speed this can be used to replicate the effect of the Spartacus VST plugin, which in turn was made to replicate a StereoMaxx. I would *not* advice very high levels here (values around 30-50% work pretty well though).

I think this description is probably unclear, but just take this from it:
- If you set Volume Effect to 100% and enable Difference mode, you'll hear that L-R is only widened after an L+R kick. What you need to know is that the speed at which settings are adjusted is relative to the output level with these settings. When there's silence you get the behavior of the previous releases (you also get that when you set Relative Speedup to 0).


OLDER:
- Added gate to stereo delay
- Added extra L-R vs L+R detection with different attack/release timings, actions are now taken based on the minimum of these two.
- Fixed lowpass filter slope and added option to set the level above the maximum lowpass frequency.
- Highpass and lowpass freqs are now locked (you cannot set the 2nd below the 1st.
- Changed ranges and default settings.
- Added settings to control limiter response speed.
- Changed default speed settings to get a much more constant sound level without jumping up and down
- Highpass and lowpass (!) filter added
- Added option to also limit the input stereo level.
- Stereo Delay now also visible in other than 'Extreme Tweaker' mode
- Stereo Delay limiter added. Also in case of existing extreme stereo it is switched off completely.
- Stereo Delay now also works with 0 delay (behaves more like Stereo Boost).
- Stereo Delay does not boost bass below 150 Hz, with a slope going up to 300 Hz.
- Natural Dynamics worked slightly different in version 7.43 and 7.44, and it turns out that it sounded worse (the bass is boosted much longer, causing excessive bass). Sound of version 7.42 is restored.
- New stereo widener added, based on techniques used in some famous stereo wideners since the 1980's. For now (I will change this) only available in Extreme Tweakers mode. See below.

TODO:
- Add Balance (for input sound card)
- think of a better name
- Make Punch behavior less complex!!
- Check nelson c's 7.44 problem (Juli@ driver issue?) (TEST IS RUNNING IN MY OFFICE)
- Wait for feedback and maybe improve stereo delay further

As previously indicated, this problem did not exist for me prior to 7.43 Beta009.

Same exact action taken in 7.43 Beta005 does not result in stuttering audio.

There was some sort of change in 7.43 Beta006, Beta007, Beta008, or Beta009 that caused the current issue. Betas 6, 7, and 8 were not built for DSP, so I cannot test them to isolate which specific version introduced, yes, introduced :!: , this changed behavior.

Again, 7.43 beta 005 = no stuttering when doing the same exact thing that causes stuttering in 7.43 beta 009.

7.43 beta 005 and older = no issue
7.43 beta 009 and newer = issue

Limiter changes, per your change log, was in 7.43 Beta010, thus they should not be the culprit. When I brought up this issue in the 7.44 thread, you indicated that you had changed something with respect to threading in the 7.43 versions in question.

Greate work again, Hans :) from what world are you again?

ST SuperWide - sounds wider and better than most analog boxes ever :) combined with the matix in the AGC this is a KILLER :) didnt know i had speakers way out there…on the outside of my car…in the other lane...

havent had any big issues on my platforms here, from pure win xp, pure win 7 (both intel and amd) to a virtual win 7 on a mac. Only issues have been related to 3rd party drivers for soundcards. Nuttin to do with ST. Keep that beat pumpin…greate work :)

+1. I'd like that as well.

EDIT: I can't run composite cliper (allone not any other feature) in full strickness with any mouse mouse movement .Even with quality set to 20% and gui display set to 0%. My pc uses an AMD Phenom 9550 Quad-Core 2.2Ghz and for ram i have 2.5GB OS: Win7
