But there are other processors as well and not only i7 47xx. And another example i can run two instances of stnone for all the audio processing and another to do the fm things with no problem. But if try to use only one st i can't because the cpu single core performancee is not all that great. But if you can add one more thread especially for the clipper that would be nice.

I am with AMD Athlon II and my own preset (not build in) and it`s not heavy.
When all options are to "ANY core" - it uses both cores with almost same load .

When i turn into Core0 all the options - it goes to first core and the other is free.

When i turn back to "ANY" - it still uses the last choosed. But when restart the program , it again uses both cores with balanced load.

That is a problem that windows have with threading. In reality ST is NOT using all the cores equally but windows make the threads jump from core to core so fast that the task manager thinks it is an equally divided workload but it really isn't. And that is not beneficial because you have one core that will do all the work again for a small period of time and the just switch to another core and so on.

On my laptop I can run any of the built-in FM + composite clipper + Stokkemask presets without any issue on a SINGLE core - so not even 2 - with plenty of headroom. That's on a laptop i7 4710 at 3.1 GHz. So... A 4790 desktop i7 at 4 GHz should really have no problem at all running this, unless something is very wrong somewhere.
Sorry, there should be nothing wrong.. I maxed every CPU settings in ST to get to that result. 4790K has 4 physical cores, and two virtual cores out of 8 were maxing out with the ultimate max settings. Of course there is a chance that some real 8 core processor will perform worse since the singlecore (or dualcore/dual thread) performance drops.

ST 7.70 on linux:

115% cpu for that process. Using everything except FM.

This is on a AMD Phenom(tm) II X2 555 Processor.

Stereo Tool 7.71 BETA002

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 71-002.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 71-002.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 71-002.dll

Some small fixes and a big code rewrite to improve reusability.

CHANGES:
- Added option to add a text in the title bar to easily recognize multiple instances.
- EXCEPTION OCCURRED IN HttpServer: Got unknown widget ID.
- CPU: Clipper: Highs gap protection: Use 1 step for non-FM.
- Check if COMMON_STATIC still improves performance, if not remove it -> Does not, removed.
- Redesigned parameter classes and moved everything around for integration with other products.
- Remove Stokkemask mode for non-composite FM clipper (it's probably not working correctly and more heavy than the composite clipper)
- Fixed small bug in Composite clipper FM overhead level compensation calculation. Might make the same setting very marginally louder (less than 0.05 dB)
- Fix crash reported in previous post
- Improved CPU load measurement (small part of code wasn't included, it is now).

OLD CHANGES:
- CPU: Composite clipper: Optimize Stokkemask: Skipping outer parts of window
- CPU: Composite clipper: Optimize Stokkemask: Fixed 'Skip smoothing' mode to be compliant, all other modes removed.
- CPU: Composite clipper: Optimize Highs Gap Protection (trick from Leif Claesson that he uses in the Omnia.9 - nearly no CPU load needed anymore!)
- CPU: Added some #pragma's to make compiler generate more efficient code
- RDS: Added some character conversions (Euro -> E, ` -> '). (not yet tested)
- GUI: Allow drawing scopes in half-height to have more headroom above and below.

TODO 7.71:
- Difference in measured CPU load is bigger than expected after CPU load measurement update - check why - DONE, is indeed big! Separate slider added to show both processing and total CPU usage.
- CPU: Clipper: Reduced default number of Bass Clipper steps from 4 to 1
- CPU: Clipper: Implemented Leif's mirrorring method for Stokkemask and optimized steps using Omnia interface, much fewer steps for same result.
- Fix CPU measurement for high loads (jumps to 95% for unknown reason).
- VST multiple instances fails
- Make VST window bigger
- Fix Mac VST version (not recognized apparently)
- Fix Linux version (someone mentioned that it crashes after a few minutes, on Ubuntu 14.04)
- Instability in compressor behavior [WesKeene, Bojcha]

TODO:
- Noise learning Micha
- Change default preset (it still uses Classic compressor etc!)
- EQ with 'standard' sliders.
- Make BS412-like graph for levels
- Add 'warm' noise before clipper (requested by Andrew Palmquist, might help with PPM as well)
- CPU: Clipper: Optimize Advanced Bass Distortion Protection

TO DO WITH LEIF:
- Clipper issues Leif / Wolf Stahl (probably the same thing)

I have big CPU load increase .
About 6.5% more according to ST red bar.

DSP, Stand alone, VST?

Edit: Ah, a small part of the code wasn't included in the CPU load measurement and now it is. So that could be it... Can you check the actual CPU load using another tool (such as Task Manager)? On my pc I see no difference there, but I do see a difference in the red bar!

It`s for Stand Alone .

I check in task manager , but looks like nearly no difference . Strange

In the MB2 you can not select the type?
