Stereo Tool

Hi Hans

Exception crash in DSP version for B036...
Rossco

Ok I can *almost* see where this happens but not exactly yet. Because unfortunately I didn't store the 036 code base so I can't go back to it. So, I will just hope that the next version has the same issue, and I *will* make a copy of it this time.

On my pc, it doesn't crash btw. (And I think I know what I did, but not where)

Edit: I found some suspicious code. So, hopefully the next version is ok.
Note: The changes that are causing issues are some performance optimizations that seem to help on the Raspberry Pi. They have no effect on Windows with the Intel compiler, but of course I want to have the same code for both versions.

7.85 BETA037

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 85-037.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 85-037.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 85-037.dll

CHANGED:
- Exciter: Improve start of filter (less steep!)
- Fix crash in BETA036.

OLD CHANGES:
- Bug in 034 should be fixed again.
- Exciter: Make it possible to choose where in the chain to run it
- Hide Stereo Tool name and THIMEO in help window in specific versions.
- VST plugin level should be ok again
- Did some optimizations for the Raspberry Pi version, not sure yet how much effect they will have (so far only build on Windows).
- Exciter: Make 2 kHz block size configurable, or automatic, or combination. Might work best if it's constant?? --> This should fix the too bright sounds in some cases without introducing distortion in other cases. I hope...
- Exciter: Optimize for LPF setting
- Plugin -> Output level doesn't work in VST version
- MB2: Make Overview window for new Multiband! For main settings.
- Woops, wrong flag set for Exciter, dynamic Squeak mode didn't work. It does now.
- "Input without processing" doesn't work in stand alone version.
- Exciter: Add Volume slider
- Exciter: Add DIFF mode
- Exciter: Try to improve tone behavior (should also reduce whole area around a spike I think - maybe configurable?)
- Add another AM test tone, sawtooth with cut off bottom
- Add 'Forcibly remove' to AM settings? Or is this a problem with the transmitter that the tester on Radioforum uses? -> Regardless, I've added it now.
- Fixed AM sawtooth test tone, adjusted level of other test tones when using AM.
- Fixed bug in HARD LIMIT introduced in BETA027 (caused crashes).
- Added slider to Exciter to choose between a more natural spectrum which however sounds more distorted, vs a very clean sound but with shrill tones in it. Will try to get rid of this slider and automatically choose the correct setting soon!
- Polar stereo: K filter added, but output is not strictly clipped anymore. Waiting for feedback.
- Add AM test tone: Sawtooth with pause at 0, asymmetrical. LPF needed?
- Fixed crackle at startup caused by Ignore high frequencies (even if it was disabled!)
- Loading old preset from before Analog mode was added apparently loads in Analog mode! -> Works now, just no idea why??
- Exciter: Crash should be fixed.
- Exciter: Sometimes you see darker bars in the spectrum, changing the overlap back and forth removes those, so somehow some levels aren't always calculated when a setting is changed.
- Fixed crash when closing
- Exciter: Moved to separate page, for now called Absolute Highs.
- Exciter: Added GUI element to show Absolute Highs effect.
- Exciter: Broken at latency 512
- GUI: Fixed hangups caused by tooltips.
- GUI: Remove dots in changed settings for some buttons on top of the screen.
- Exciter: Made frequency range configurable!!! (Old default numbers were 8000-9000 Hz)
- Blog post pre-processing, MP3 and declipping
- GUI: Added tooltips!
- Added exciter (rest of list removed)
- Added (not yet fully ok) Polar Stereo support for OIRT FM stations.
- Error (crash) on some systems should be solved
- Show something in settings that have been changed (for example a dot next to the name of the setting).
- Add license check function: extern "C" bool stereoTool_IsLicenseValid(gStereoTool* st_instance);
- Make scope skinnable
- Bug: i found one malfunction in the BS412 Section: If your switch off the FM Option and leave the BS412 Limiter in On-Position the Advanced Clipper only works in a reduced way: You can´t change the Clipper drive even if you pull the handle. The BS412 Limiter is greyed out instead so maybe someone doesn´t find the failure. If You switch the BS412 to off everything works fine again! Just a small detail, but maybe someone will have problems… -> I think I have fixed it (but there are a lot of different combinations of settings that can impact the result, I hope I haven't missed any). The next version shouldn't have this problem anymore, also, when BS412 is used I have now disabled the Advanced Clipper Drive slider.
I've been busy hiding a lot more deprecated features (if they are set to their default value). This should make the GUI a bit simpler. Stuff that's now hidden (still there and still functional if you really want to use it):
- "Bass AGC (Old)" panel
- "Classic Multiband Compressor" panel
- "Classic Singleband" panel
- "Pre-limiter" panel (in Advanced Clipper)
- "Leif's clipper efficiency modification" checkbox
- "Composite clipping Strictness (CPU)" checkbox
- Phase rotation: ""At start of processing" checkbox
- AGC "Compatibility & behavior" header
- All Singleband and Multiband "Compressor type" (Analog/Digital) pull-downs
- Multiband and Natural Dynamics "Compatibility mode (bad)" for Flat Frequency Response checkbox
- "Bass protection (Deprecated)" header in Advanced Clipper -> Bass
- "Highs gap protection: *" in Advanced Clipper -> Highs
- "Smooth slope" in Advanced Clipper -> Distortion
- "Upsampled highs clipping (useless)" in Advanced Clipper -> Distortion
- Stokkemask: "Force Stokkemask even if not using Composite Clipping (bad for audio)"
- BS412: ""De-basser non-ITU.1770 compatibility mode (bad)"
- Right clicking now restores default again, mid or double right clicking restores last loaded preset (or startup) value.
Bug: If you use FM and Normal output, with separately processed audio for streaming for Normal output, and for FM output enable pre-emphasis but *not* pre-emphasize output, then Normal output is not processed separately!
- What is the pink line in the BS412 display? Maybe remove it. http://i.imgur.com/70mWvqp.png -> Ah no, it's the adjustment of the compressor thresholds. Needs to be added to Help page.
- BS412 has VERY narrow jump on de-basser from 240 to 250 Hz. (Jump of multiple dB's). -> No, brown line jumps but actual output is smooth, so no problem.
- BS412 bass filter doesn't use ITU1770 as it should but some weird other shape that goes up to about 250 Hz.
- Need to support 2 default values and a RESET TO LAST LOADED VALUE reset option.
- Hide not selected deprecated stuff - partially working!
- Move Copyright stuff etc. also to command line version (maybe just copy it?)

TODO:
- Voice protection in classic MB is broken. Check what changed. (Code should not have changed at all). - Hm, more has changed. Check in which version! -> Waiting for reply to question -> Compared again, and the distortion is caused by the singleband compressor that's used afterwards. Which does indeed get a slightly louder input because a (wrong!) filter has been fixed since that version.
- MB: Make Overview window for new Multiband! For main settings. Hide other windows when possible, and also make it for MB1
- Exciter: Try to reduce pre-ringing (maybe by doubling overlap? Or measure on bigger block size, then go back to smaller?)
- Exciter: Add auto-adjust HPF frequency
- Add Polar stereo viewtopic.php?f=16&t=6233&p=33031#p33031
- Put in Ben Liebrand settings for vinyl cleanup?
- Test "looper" optimization on Raspberry Pi 3
- Command line version doens't like long name (Antenne V. - see mail 2-3-2016 22:24).
- MP3?

LATER:
- Try adding phase delay compensation
- Also show tooltips for blocks of parameters.
- RDS encoder: Use Mathijs' method with interpolated 0's. Should give a nicer signal! Also I saw a weird jump bug in the raw (unfiltered) RDS output. Shouldn't matter (it gets filtered out) but still better to fix it.
- MB: Add voice volume protection, don't allow mid bands to drop below surrounding (to some extent), protectes voices and it might help to replicate the sound of certain other processors
- Continue with finding parameters to hide
- O skin

Beta037 still causing exception. Checked both the DSP and stand alone versions - both are throwing the same error.

Hello Hans,


Is there an Windows VST 64 bit Beat version?

Best regards,

Benny

beta 34 VST was silent and would hang the audio path in Reaper. somewhere it got fixed because beta 37 VST works fine.

What is a Beat version? If you need 64 bit, for now you'll have to use the release version (7.84).

I'm trying to find what's causing this, but it's problematic because I'm running into compiler bugs which makes it nearly impossible to debug the code and see what is happening exactly. Can you try this version and send me the error message again? That should help... Thanks!

I guess that was a typo and Benny meant a 'beta' version.

Hans - sill seeing Exception error in 37A.
What I have noticed -:

- Winamp will play audio (with sound unprocessed).
- Stereotool GUI is not active at all (no movement in console meters whatsoever).
- It will not show the exception error until you mouse over the GUI.
- Closing Winamp causes it to crash on exit.

Hope that helps in some way?
