Stereo Tool

Monitor buttons in the new gate panel are above left menu (some GUI mess). Please don`t tell me it will freeze again

Also when i was sliding the "release gate freeze" option got this window (see second picture).I think it`s caused by this GUI mess with the Monitor options.

I must tell you that in MPX spectral display there is some different in the pilot tone illustration.
Before some betas (i think first ones) "the 3rd harmonic of 19KHz" was not visible .
Then in some moment it come back again . I mean when no RDS on .
but the strange thing now is that the "peak" of pilot tone looks different . And this "change" is due to this beta development from 7.60 ahead.

So, take some of the first betas , let`s say beta 5 or 10 and see pilot on MPX display . Then open last betas and see the difference.
Will this cause something on the whole MPX signal ? Or it`s only a display "bug" or bad drawing .... or may be this is the right drawing?

Hans the gate (even on -99db) had effected the attack and realease speads . They are MUCH slower.

Are you using a value below 50.00 for the Threshold values? Because I had before put in a compensation for that but I noticed that it made it much harder to control things, so I removed it again.

if it's that, then it's unrelated to the gating.

BETA 761-032

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-032.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 61-032.exe
VST 32bit: http://www.stereotool.com/download/vst_ ... 61-032.dll

CHANGES:
- Optimize gating (turn off if not needed)
- Made 'limit before compress' again, switchable

OLD CHANGES:
- Add Gate for new compressor release (also GUI)
- Band Link etc. does not work in 3-band mode, and it should for AGC-type behavior.
- Simplify interface (remove Oil Speed Adjustment sliders etc, move some things to Extreme Tweaker mode)
- Adjust limiter level for Band Mix
- Fix 'Load default values' question for MB #bands change
- Make Shape value small for high speeds - TO BE DONE: Test if the border value is chosen correctly (shape effect is deminished below 40 ms, reduced to '1' for 0 ms; not sure if 1 is low enough?)
- Fixed some more GUI crashes. They should all be fixed now...
- Check if audio is still the same as in older versions (!)
- Set MB2 default settings ok for NAB demoing (very fast)
- Fixed some (but not yet all!) GUI crashes
- Improved CPU performance a bit, on multiple places (clipper, GUI).
- GUI crashes from previous beta's are probably fixed (?)
- Changed some GUI things (for big displays)
- Small performance optimizations
- 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:
- Improve limiter GUI display
- Don't allow Threshold values below 0.5 dB (singleband, others are already ok)
- Improve gate GUI display
- Make after-AGC SB compressor switchable as well
- OPTIMIZE LIMITER
- Maybe add downward expander

TO DO:
- EQ with 'standard' sliders.
- 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). Also finally make resampler for normal output to fix 2 output on different sound cards problem. Move Resample setting from input to output. Let's ignore using 2 inputs for now...

I decided to try build 32 (winamp plug-in) with RadioBOSS today. I'm using an STS that I built using Winamp with build 32. This build, with the same STS, works fine with Winamp. When the DLL is selected within RadioBOSS I get the following error:

Access violation at address 0834DD8A in module 'dsp_stereo_tool beta 32.dll'. Read of address 00000000.
Program will be restarted because of fatal error.

RadioBOSS records the error, then restarts. Note that I renamed the DLL to avoid overwriting the current, production release version.

Ideas?

Not yet. Did this happen the first time you loaded it? And you haven't used this file name before? Because if so it will just start up with the default settings, otherwise it could be a setting that you're using.

It's particularly strange that you're getting this message not as a popup inside Stereo Tool but in RadioBOSS, because most of the code is guarded by checks that would cause it to be reported internally.

I have received another report from someone who cannot open the GUI after minimizing it in the last few betas, it might be related.

Each time that I select the DLL for use (in RadioBOSS' "FX" tab) the error is reported in RadioBOSS. I am attaching my settings file to this post. I hope that it is useful.

I'm also adding a screenshot of the error inside RadioBOSS, although I suspect the screen capture doesn't add any additional data.

Bandmix still before limiters.

Yes that is not right. Hans please move the band mix after the limiter.
