Hmm... this stand alone version don't start with my win7 64bit i5..
Error windows message box "ST stop working.." , I can't show all screen because language is not English.
Was the previous beta ok for you? Or didn't you test it?

Does the GUI appear before you get this message? Audio starts playing after 1 second so if it's something in a preset that triggers it you should see the GUI, then after about 1 second it should lock up with this message.

Important question: Which i5 series is it? 2xxx, 3xxx, 4xxx?

I don't know which previous version was ok, because I don't test every beta.
Main window is visible for about 2 seconds and next windows error message like "ST stop working...".
I'll try to clean up any old ini files later.

After I cleaned .ini files start ok, but now I found the problem why it does not work - it happens when select VLC input.

Confirm when selecting VLC input - ST crashes

Previews beta had a strange problem... Sometime has no output sound but the meters shows that it works perfect. No output sound.! i will try this last..

- Compressor/limiters: Moved limiter before compressor. This slows down the attack speed when limiting occurs, which gives a more stable sound.


Because of my time, I fail to look at the forum every day, but last night I did and I have not lived a pleasant surprise when I saw that the limiter compressor has gone before!
This really does not have ever seen, see above it says for the audio gets more stable compressor. This is a mistake, as the audio compressor just should not get so stable, only the AGC performs this function.
Since the dynamics of the audio should be changed from low to high (ACG-Compressor-Limiter-Clipper), or did someone put a clipper before the ACG?
If one limits before compressing, you lose any chance to work with dynamic compressor, which is the essence of the sound of a processor.

That is why, I think this is a mistake, at least for me it is, as an alternative I think you should at least leave a checkbox to use before or after the compressor. :|

There continues to be quite a bit of misunderstanding about this feature. In a subsequent post, it was pointed out that the limiter is definitely NOT before the multiband compressor. What the change actually did was make the multiband compressor's attack ballistics behave *as if* the limiter has already been triggered beforehand.

So imagine a sudden and large increase in gain in a particular band. The multiband compressor might be tempted to try and attack very quickly on this peak. Instead, with the new feature, since it *thinks* the limiter has already been triggered, it attacks in the normal way you'd expect. As a result, the multiband compressor doesn't overreact and sounds more stable.

VLC issue is solved. Oddly, it turns out that some variable types were changed in the 32 bit version of the compiler, which caused calls to VLC to encode a 64-bit address with (in part) bogus data. Whoops! And since the crash occurs inside VLC and not inside Stereo Tool (VLC tries to call Stereo Tool with a bad address), there's no way to handle it nicely and show a popup window with a proper error message.

32 bit version is ok, will now test the 64 bit version.

I have also finished rewriting (optimizing) the Stokkemask code, now for all modes (not just 'Faster' mode).

BETA019:

VLC crash should be fixed now. It works fine here.
Stokkemask CPU load optimized for all settings.
Bug in Stokkemask and Multipath Clipper fixed that makes it work better.

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 51-019.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 51-019.exe

Windows 64 bit:
http://www.stereotool.com/download/ster ... 51-019.exe (NOTE: NOT AN INSTALLER - this is the executable).

CHANGES:

TO DO:
- Improve web interface further.
- Fix RDS clock on 64 bit
- Add presets


OLDER:
Stokkemask CPU load optimized for all settings.
Bug in Stokkemask and Multipath Clipper fixed that makes it work better.
- Added faster processing paths for SSE3, SSE4.1/2, AXV and AVX2.
- Optimized Stokkemask filter (so far only in Faster mode, will optimize the other modes later). Filtering is slightly less good, although I don't see it in the measurement results.
- Changed band steepness minimum values for multiband from 6 to 3 dB/octave. (Ooh. I hope i changed MB and not ND...).
- Added a bunch of new presets. Some need to be updated again. And the Jeroen Platenkamp HvZ mod version is currently identical to the original.
- Web interface drawing of equalizer fixed
- Crash when loading some presets fixed
- Bug fix: Prelimiter acted up at certain latency settings.
- Web interface dragging fixed.
- Bug that caused sliders and top menu to stop working fixed.
- Calculation of FM MPX left/right peaks was wrong when using Composite LIMITER, fixed.
- Made left/right display green (with above 100% yellow) as suggested by mpex2006km.
- Improved web interface a lot more ("1000" is gone, more displays are working, right part of display auto-scales to device width)
- Fix MPX Power calculator
- Fix resetting of tilt calibration when loading a preset
- Add volume meters which show > 100% modulation for IBC demo :)
- Bug fix: Single-channel file in plugin version caused crashes when using the composite clipper.
- Compressor/limiters: Moved limiter before compressor. This slows down the attack speed when limiting occurs, which gives a more stable sound.
- Improved web interface. (Not yet finished).
- There's some weird sound audible when you enable 'DIFFERENCE' mode. Even if nothing happens. This means that the audio is somehow damaged. It's worse at lower latency settings. FIXED
- Make highs clipping level configurable. DONE
- Fix composite clipper mode. DONE
- See a few posts up. I've now added 2 sliders that can be used to reduce the effect when there's not clearly a tone present. Tones only reduces the effect when there isn't a single tone that clearly sticks out - basically it checks how loud the strongest band is vs. the total of all bands, and adjusts the effect based on the result of that calculation. Since there are almost always also other tones present, setting this too high will even reduce tones that do clearly stick out. Tones threshold can be used to turn the filter off completely if there isn't a single tone that clearly sticks out (it makes the slope of the Tones only effect steeper).
- Changed some things back to how they were in version 005 - Bojcha reported (and I confirmed) some weird artifacts in version 006. If you enable METHOD2 you get the 006 behavior, that's for my own tests and I will remove METHOD2 later.
- Added Smother filter. The higher you set it, the more it will ONLY affect the loudest sounds. If you have multiple loud tones (for example a bass and a loud voice), setting this very high might cause only one of the two to be effected - setting it very low will affect everything though.
- Added multiband pre-limiter/phase optimizer to the Advanced Clipper.
- Trying a different multiband limiter in the Advanced Clipper. This time without phase optimizer. I'm very curious which version you guys prefer!

Using lower limiting levels lowers the loudest sounds in the mix. Since bass is often the loudest sound it tends to reduce bass more than other sounds.

I still do not understand, is changed or not place the limiter?
However, the scenario mentioned, is solved by a type detection RMS and adjusting the integration time so that the peaks do not create this situation.
