- clipping in limiter is better! Hard Limit is not needed. On FM when Hard Limit is OFF, composite limit should be at least at 101%. Strict limit is still same. Still makes strange sounds. I keep new slider to +6...
Hi Bojcha,

I don't really understand what you're saying. Clipping in limiter?! And which strange sounds are you talking about - when do they occur?

@ Hans, i just saw your post about Hard Limit..
What i am seeing is.. when PostAmp is at -0.08dB and new slider at +6, HardLimit=OFF, i have just sometimes 'red' Output Meter meaning, overshots.. and it is mostly on highs! Again meaning, that Hard limit will lower ALL signal in that moment for about overshot size.
Now that peek is much lower but it's still there. And Hard Limit does not like Highs.
Hard Limit should have FAR less trouble with highs than before, because before only the final clipping step and Hard Limit used upsampled audio, now ALL the clipper steps do - so at the end there should be far lower high frequency peaks.

I have an optimization (basically a clipping shortcut) that should make the clipping more efficient, reaching roughly the same levels (but probably with a slightly lower RMS output level) using less processing steps. It's one of the filters that I've disabled for now (mirroring).

BETA084:
- Declipper bug fixed: It could get EXTREMELY slow when long blocks of clipped data were fed into it (DC input for example). This may have some effect on the clipping detection! CPU load should be considerably lower now if a lot of clipping occurs on low frequency tones.
No change in CPU load for the slowpoke... Still needs slider all the way negative to still have ~10% additional load vs. 79.

As noted though, there seems to be less need for hard limit, IF you have the slider at 0 and higher, which...slowpoke can't do without usage going up to 80-90% (cummulative total for everything enabled in my preset). :(

syntax error :D
I was thinking 'clipper in loudness filter'

Hard Limit: since there is much less job for it, maybe you can make it more 'hard' then.

And still in VST AGC bass channel sliders don`t work ( still 0.000 whatever you take the sliders indicator not moving only when move to the below 1.00 clipper appears )
Stand alone isn`t like that.

Already did that :-)

- In FM calibration: Fixed behavior for 20 Hz and 57 Hz sliders. Others were reported to be incorrect, but I tested them (measured the MPX output) and they work fine...
It's still not working the way it's supposed to be.
Try the following.
Press reset, set FM transmitter on.
No stereo/rds/pre-emphasis.
Set the soundcards correct.
Set 23,28,33,38,43,48,53 kHz in transmitter calibration.
You should not hear this sounds.
But i can hear them and see them on the pira analyzer that they are stereo decoded. Because when i select the 38 kHz test tone there's no peak at all.
But you can try this too with VAC and MPX tool. Set MPX tool to Composite mode.
This tone should be 33 kHz !!

Hi hanz,

what is it ?

"Use DLL name in INI file name (requested by Jazler)"

Thanks

If you install 2 copies of Stereo Tool, say - for example for the Winamp versions - dsp_stereo_tool.dll and dsp_stereo_tool_2.dll, then with this change the 2nd one will store its startup settings in dsp_stereo_tool_2.ini. So this allows having multiple Stereo Tool copies with each their own settings. Will also work for the stand alone and other versions.

@eldoradofm: Ah, clear. What happens here is that my tone generation code doesn't check if the samplerate is high enough. The correction itself works fine, it's just the beep tone generation that's wrong here. Will fix it.
