For me it`s imposible to continue to use ST when enable the "Ignore high freqs" option.
It`s the beta009.
ST freezes and shows this :

Edit : After close and reopen ST is running .
Ok this is helpful! Looks like there's a memory alignment issue, it appears that on newer hardware (i7's) this doesn't show up as an error anymore so I don't notice it....... Will look into it!

As i always said: AMD sees it all :)
Hmm, my i5 laptop saw this same error, I think!

I think the 4000-series don't. Maybe the 3000 series as well, not sure... 2000's and older will.

Yep, mine is 3000 series.

I will compile a version with no support for 3000 and 4000 features, that should crash here as well. :)

I think I've fixed the worst bugs (those that caused glitches, clicking sounds, hiccups and crashes). Some other bugs are NOT yet solved!

Stereo Tool 7.71 BETA010

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 71-010.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 71-010.exe
Windows 32 bit VST: http://www.stereotool.com/download/vst_ ... 71-010.dll

Still valid:
This version has a new slider, 'Ignore high frequencies above' (under CPU & Latency). You can enable this and select a frequency (19 kHz should be good for FM, since anything above 16.4 kHz needs to be removed anyway). This allows the processor to take some shortcuts... Which reduce the CPU load (more so at 48/192 kHz than at 44.1/176.4 kHz). This setting affects ALL the filters in Stereo Tool, not just the final clipper.

Old:
There are some big changes in the Composite Clipper in this version. The sound should be the same as before (within 0.02 dB or so). CPU load is much lower though. Please be careful with using this version for anything else than testing until proper functioning has been confirmed.

Note: If you want to use the new composite clipper CPU load optimization with Stokkemask, for now you should set the Stokkemask Quality slider to 3 (I still need to fix that).

CHANGES:
- Fix optimizations
- Fix code #warnings
- Improved highs filtering in Clipper (both Composite and Normal); sound has more brilliance and suffers much less from ducking on loud sounds.
- Fix bug: NAN's can occur at certain input sample rates (40960 Hz among others)
- Fixed downsampling/resampling issues.

OLD CHANGES:
- Made several changes to the Clipper that affect the sound! Sound should now be more open en brighter (but it might have more distortion in some cases, I hope not though).
- CPU: Added 'Ignore high frequencies above'.
- Big Composite Clipper CPU load improvement: Added a new slider ('Oversampling Quality' or something like that); CPU load reduction is HUGE and effect on peak control (for values above 4) seems very small.
- Solved a number of warnings that I added in the last few days
- Some small optimizations
- New Highs Gap Protection improved, now similar in behavior to the old one. I had to add 1 extra step (slightly higher CPU load).
- Fixed problems in 771-004. Some optimizations are disabled - I need to fix that.
- Fix CPU measurement for high loads (jumps to 95% for unknown reason). -> Showing real average instead of median now. Median in dark red.
- 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.
- 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).
- 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:
- Fix downsampling and Quality slider problems.
- Turning "Bandpass" Highpass filter OFF doesn't really turn it off (!)
- Remove "Take some shortcuts" under CPU, probably broken! And has not much effect anyway. -> Hm, no, must have been in use for the tests. Ugh... TEST to check what is better: ON (which will probably allow more sounds through) or OFF.
- Ignore frequencies above a specific frequency -> Should lower TOTAL CPU load by another 10-20% -> Started working on this
- Synchronization is broken in 008 (was ok in 007)
- Another bug in latest beta - ST doesn't remember FM settings - presets from the fm list start up with stereo and rds encoding off
- Fix MPX display sample rate issue
- Fix Stokkemask in Leif's mode with Quality < 3
- 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)
- Clipper highs improvement
- GUI integration for Multiband?
- 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)

If new "Ignore frequencies" is enabled, some issue with sinchronization is occured.

It began to act in some crazy way ! And FM output buffer ( may be and Normal output buffer ) starts to "shake".

May be some problem with resampling if this option is enabled ?
Also enabling and disabling of this option causes some kind of "hicup" in sound. This can be fixed ?

Latest version ( may be not only) has some distortion issue !!! Very bad .

If interested - i can do a screenshot. This was not introduced in prevous betas and versions.
I don`t want to take back to check from what beta is .
