Stereo Tool

...Yes!!! That's largely right!!!...

Could someone clarify what the Separation slider (0% - 100%) under "Multiband" --> "Levels" does?

I thought I knew; I figured it allowed the stereo channels to be processed independently... then I slid it all the way over to 100% and started seeing red in the multiband levels and worried it was some sort of limiting or clipping.

Does anybody know?

The limiters in the new multiband are 100% L/R coupled regardless of the separation settings (probably a bug).
What you're seeing (the red) is the limiter.

Right.
Red is the indication for the burst protection.
If you increase the separation slider there is a bit more level coming out of the Multiband compressors (when you see stereo level), the (coupled) burst protection and/or limiters are fed with more level so more gain reduction occures in these stages.

Hm they should be 100% separate...

BETA 761-026

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-026.exe
Winamp DSP: ----://www.stereotool.com/download/dsp_stereo_ ... 61-026.exe
VST 32bit: ----://www.stereotool.com/download/vst_stereo_ ... 61-026.dll

CHANGES:
- GUI crashes from previous beta's are probably fixed (?)
- Changed some GUI things (for big displays)
- Small performance optimizations

OLD CHANGES:
- Limiter behavior visible in meters
- Fixed MB ITU mode.
- Fixed Median display in Analog mode
- Made final SB compressors switchable, parameters are also shared between analog and digital now.
- Added limiters to singleband and multiband Analog compressors. Warning: Meters are not yet visible in the GUI! Which makes it kinda difficult to setup (you can use Monitor to see the output of a single band and then adjust the limiter setting).
- I fixed something in the GUI but I had a situation where I couldn't start it earlier tonight so it's probably not completely fixed yet.
- Some settings from the 2nd MB overruled the 1st, causing all kinds of effects. That has been fixed now, and I verified that the audio of Digital mode in the 1st MB is (nearly) identical to that of BETA761-016 (nearly because in 016 the frequencies still were 10% off). New quickly put together preset (NICE2) attached.
Fix MB frequency band shift (10%, since 7.51 or 7.60) - Appears to be gone but I don't remember fixing it (!)
Fix RDS time issue! viewtopic.php?f=6&t=5941&p=28209#p28209
Added 2nd Multiband compressor! Example preset is attached below. To me, turning it off makes the sound boring/empty. I think this is exactly what some people were missing in Stereo Tool. And with 2 steps the audio is also more consistent than before. RMS/ITU based preset would probably be even better... To increase or decrease the effect, adjust the Density slider of the 2nd Multiband compressor!
- Optimized CPU load. CPU load now strongly depends on the settings, for the settings that I posted earlier it's now less than half that of Digital mode! On my system it went down (single core mode, CPU load on that core) from 12.3% to 2.5%! (Again, depending on settings). Digital uses 9.1%.
- Merged more parameters (Peak vs RMS setting) with old ("digital") compressor.
- Slower Release speed in Analog compared to Digital
- Removed Shape Enable settings.
- Fixed Knee in Analog mode
- Fixed Aggressiveness slider behavior for Analog (!), made it behave the same as Digital mode (acts only on release speeds).
- Merged more parameters (Attack Time, Release Time) with old ("digital") compressor. Adjusted numbers in Digital compressor to match the (correctly calculated) behavior in Analog mode.
- Merged parameters (threshold, knee, ratio, feedback, channel separation, band mix) with old ("digital") compressor, I noticed that I was switching back and forth all the time to copy settings, so this seems easier. Threshold is now also displayed in dB's.
Made Multiband version of the new compressor! Choose 'Analog' mode to switch to the new one. See attached preset for an example!
- Made new Traditional Peak mode which behaves more like normal Peak.
- Added Lookahead, removes huge spikes at start of attack for fast attack times and reduces IMD.
- Fixed Ratio behavior
- Fixed 'Density Drive' slider in Analog mode
- Fixed no audio with certain combinations of filters
- Fixed a filtering issue in the Digital compressor (!) when using Density Drive > 1.00
- Added lowpass filter to control signal to smooth out bad effects and remove distortion
- Added ITU-1770 mode to reduce pumping and improve level control
- Added Channel separation
- Rewrote all code
- Fixed Ratio
- Channels are not processed separately (wasn't the case before, and that was a bug)
- Fixed attenuation display
- Attack and Release times must be set to half the numbers of the previous beta's. Oil change speed must be doubled.
- Restored old Shape behavior from version 009
- Replaced 'Nonlinear Release' by 'Exponential Release', which works better and only needs 1 parameter. Use this to go up FASTER if you're down DEEPER.
- Added Ratio
- Added Feedback mode
- Fixed out-of-control behavior for certain extreme settings
- Fixed some more weird behavior things if the difference between Attack and Release is REALLY huge (behavior was bumpy and caused clicking sounds).
- Known issue: both Shape On settings must be enabled. I will probably remove them in the next build anyway so I'm not going to fix it.
Fixed a lot of bugs, will type the details here later. Oil Temperature is now in % and didn't work properly before. PLEASE LOAD THE DEFAULT SETTINGS for the new compressor or it will sound horrible.
Changed Attack Time, Release Time, Attack Speed Threshold, Release Speed Threshold to understandable values. Made 1.0 the 'standard' behavior for Shape.
- Added smoothing to oil temperature behavior for both attack and release.
Added Oil temperature behavior which was missing from my automatic (hydraulic) door model. Will explain below...
- Added another Peak mode slider in "New Singleband". The old one (from yesterday) works mainly on release, but in some cases the volume didn't go down fast enough on a loud sound. The new one works mainly on attack (higher value makes attack continue AFTER a peak.
- Changed Peak mode behavior in "New Singleband".
- New Singleband: Split Speed into Attack and Release Speed
- New Singleband: Made Attack and Release Speed Threshold relative to Speed - so you don't need to adjust it to change the shape.
- Added new Dequantizer filter to increase the bit depth of recordings.

TO DO COMPRESSOR:
- Check if audio is still the same as in older versions (!)
- Set MB2 default settings ok for NAB demoing (very fast)
- Simplify interface (remove Oil Speed Adjustment sliders etc, move some things to Extreme Tweaker mode)
- Make after-AGC SB compressor switchable as well
- Add Gate (also GUI)
- Make Shape value small for high speeds
- OPTIMIZE LIMITER

TO DO:
Add RDS control via VST typedef VstIntPtr (VSTCALLBACK *AEffectDispatcherProc) (AEffect* effect, VstInt32 opcode, VstInt32 index, VstIntPtr value, void* ptr, float opt); for Bernd N
Clipper issues Leif / Wolf Stahl (probably the same thing)
Improve Dequantizer by combining data from different block sizes
Add HD delay (upto 10 seconds? Check Matt Aaron's drawing)

I see big problem with gui on win7, all is white and I can't close ST.

GORGEOUS!

Thank you so very much!

Yes, I'm using Win7 x64 and it was fine until I resized the window smaller and then when making it larger it was white. Restarting it was white until I sized it back to a large window and then restarted. Definite a GUI problem. Sounds great tho, when playing, and layout looks good too. Closing it was no problem for me.

I was just wondering Hans, if you ever thought of making a layout that would switch off the config menus and just show the graphics/meters, of course with at least one button to show the config menu again?

Also are the VST x64 a lot of work? Since you're not making any lately.

I tested stand alone only.
