Stereo Tool

I finally found what was causing the highs distortions i heard earlier. It was a fault in my transmitter but i repaired it now.
I noticed the check box Advanced extreme highs protection isn't saved to disk. And also the Order of Never phase linear.

I told you so...
That's why we need this http://www.sigmacom.org/product_info.ph ... 0810f74555
I would love to have one...

Should the de-clipper work in beta35 ?

I use Sigmacom DDS exciter and the specs are exactly as writen on the website!
Completely digital , no distortions, no DC sounds!

Harmonics and spurious are far below the FCC limits! -90 db!

it WORKS !

call them for prices
+30 is the countrycode

Rechte stukken herkennen via 2D FFT?!

hm?

BETA036:
Reduced CPU load, now equal to that of 6.10 (on my pc). May have some VERY VERY minor effect on channel separation (although I have not noticed it). I expect to be able to lower the CPU load a bit further in a day or 2.
No further changes.

TODO:
- Fix loading changed multiband frequencies
- Add buffer and filter for SCA output (SCA1 ok, SCA2 ok)
- Finish AGC improvement - make mono value configurable (replace checkbox by slider) 1 hour --> NO, not needed - anything else needed? -> NO
- Fix Punch
- Check what to do with new filters (such as bass AGC) - keep them, remove them, change them? --> KEEP
- Save new BASS_AGC setting in VST mode
- Loudness: Annoying cracking sound in bass. Slightly present in 5.00, worse in 6.00, maybe even worse in 6.10. Only when bass is too loud. Much worse than in Final Limiter (at same input level!) - so this clearly indicates a bug. Most likely cause: The filter that was added to remove bass artifacts....... - No, it's the louder bass. But it can be fixed by changing some settings. Default settings updated, and behavior for 'not Very strict' improved. Also Deep bass boost and Very deep bass protection are enabled for latency 512 now.
- Fix crash at program close
- Fix VST plugin version (does not run)
- Dynamically drop 'Allow louder highs, even if it causes vibrations' to 0 when bass filter suspects noticeable voice vibrations. 1-2 hours
- Reduce Loudness CPU load days?
- Check and remove static variables
- Finish new de-essing filter (check what to do with the settings, remove at least some!) 1 day
- Convert Multiband input to MONO, then use arrays [2][4096] --> should give speedup.
- Finish declipping filter (clipping level detection + level reduction in dB). 2 days
- Update presets? (BASS_AGC etc.) 1 day
- Finish blind interface
- Add AGC start level
- Change version number 1 hour
- Release 1 hour
- Add lowpass filter for stereo signal (will cause a lot of extra latency!) - it might be possible to avoid this latency using a Hilbert transform
- Add smarter clipping detection. Maybe something much simpler suffices: Current clipping detection with threshold + flat line detection

Good job on the code optimization / cleanup. Beta35 still had a 5-6% difference with the GUI up vs. minimized. I don't see a difference now with 36.

Finally....after endless hours of searching i finally found the culprit that makes my sound knacking. It was the onboard soundchip! Even simple computing processes probably influences the sound output, argh.... now i throw it all to hell and get a good soundcard.

Sry if i thought it was your program.

Hans,
I like beta35. Moving the buttons around so windows fit on smaller screens was great. Keep this in mind, all monitors are now in widescreen which mean the old 1024x768 is no longer applicable really. My monitor, for example, is 1280x720...It is 720 instead of 768 because it's made for movie watching. My suggestion is this: try your hardest to keep each window able to fit on 1280x720 because all monitors these days don't accept anything smaller (800x600 for example). If it can fit on x720, it can fit on x768 and up.
Also, speed is good now on the latest beta and I think you fixed the AGC starting at max like we talked about, at least it seems like it.
The only thing on the TODO list I think is most important right now is to fix the punch. That's where computer sound processors seem to struggle (at least from my experience). So if you can master that, that would be great.
Keep it up Hans!!!!
