Stereo Tool

Please please please please , touch the code of stereotool " gently " like a gentleman becuse it will break!!!!!!!!

If you CAN reduce the CPU load without reducing the processing quality then reduce it
If it is not possible to do that , it is better to not touch the code further :!!!

I PREFER TO HAVE A 4CORE COMPUTER WITH 300 EUROS AND RUN STEREOTOOL SAFE THAN TELLING HVZ TO MAKE THE PROGRAM LESS CPU HUNGRY.

Come on!!! , we use a 20 euros program called stereotool that WORTHS MORE THAN 9.000 EUROS if it was a special optimized OS with special hardware , and ...we cannot buy a 300 euros 4core computer ?!?!!?!?!?

buy a computer !

I'd be happy to provide a way for you to send me cash via Western Union so that, given the fact that I'm unemployed, I could do just that.

I look forward to your message contacting me on your willingness to do so...

Poorly performing code needs to be optimized, otherwise it becomes what's known as "bloatware".

With beta 31 and 32 I'm getting a blank white gui window with the vst version...
Beta 28 worked fine.

BETA033:
Optimized 'S' protection: Turned off some older "S" protection code that is no longer needed (I think). Effect on the audio is that the mids are slightly louder, highs are slightly softer --> in other words, loud mids push the highs down a bit. (You can still turn it on by DISABLING the new checkbox at the bottom right of the Loudness panel - if I get no feedback that this sounds better I will remove it later).
CPU load is now slightly less than 10% higher than that of version 6.10.

Added VST plugin issue to TODO list. (actually it might already have been solved, but I haven't checked it yet).

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
- Reduce Loudness CPU load days?
- Finish new de-essing filter (check what to do with the settings, remove at least some!) days?
- Dynamically drop 'Allow louder highs, even if it causes vibrations' to 0 when bass filter suspects noticeable voice vibrations. 1-2 hours
- Finish declipping filter (clipping level detection + level reduction in dB). 2 days
- Update presets? (BASS_AGC etc.) 1 day
- Finish blind interface
- Fix VST plugin version (does not run)
- 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

At the moment it works fine! I record now a long mixdown (more than 5 hours) for my ipod with different styles of music using mAirList and the VST-Plugin. It seems to me that the S-Protection works cleaner than before and the CPU-Power is about 30% (Intel Celeron 2 x 2,4 Ghz; 4 GB Ram).

For me with my Preset it sounds really good.

One thing: The Pre- and Post-Amp-Faders doesn't works with my mousewheel for adjusting in VST-Version, but with DSP-Version there's no problem.

No, it most certainly IS NOT.

Again, when the GUI is UP, the CPU load goes UP by a significant amount when the Advanced Extreme Highs Protection is enabled. Significant Amount = 50% (from 43% up to 66-72%, an increase of 50% or so).

When the GUI is DOWN in the tray or otherwise not visible, the CPU load is BETTER, but it is still a increase of 20-30% (43% up to 50-55%), but only if you check "Simplify Triband". If that box is not checked, CPU usage is right back into the 60s...

DSP version.

beta33 Testing FM Output...

I have very good results with this settings for 'advanced extreme highs'

- Allow louder highs 2.00
- Dyn De-Esser: 500%
- Maximum divider 5.00 (still not sure about this one)

With this settings there is much less level drop (caused by loud highs - {loud S}) and loud high tone (like loud S) is better kept.
But there is still slightly volume drop .. and this might be really in Loudness.
So my theory still standing that Loudness filter is working more like 1-BAND limiter, and it is needed to work, atleast like 2-Band.

Another one theory is that "Andvanced extreme highs protection" should be part of Composite Clipper.

Related: De-Emphasised output in Omnia.9 (more then 0dB), are actually Highs and mid-highs. Don't know where exactly is 'intersection'. somewhere at ~3-5kHz.

I have a new version ready where the cpu load is dropped further - unfortunately my internet connection is currently down...

VST plugin issue (blank white gui window) is solved in beta 33. Tnx!

Hi Hans.

I´m from Germany, and i love your nice little program. Personally i use the Winamp plugin. Until now i was very satisfied with Version 6.00 (final) - except the deep bass, which sometimes slightly oversteering. Thatswhy i tried 6.20-BETA030 (edit: BETA33, sry) and i have to say, it doesnt convince me. Without Declipper the highs are snapping and clackling slightly more than 6.00 (hard to hear but they are in), with Declipper turned on it ruins the song. CPU load between 20-25%, Intel Core I5.

Listen for urself: http://www.filefactory.com/file/cb227c4 ... eeling.mp3

First 60 seconds recorded with 6.00, next 60 seconds (same songpart) recorded with BETA033 without Declipper, rest of the song - Declipper turned on, Quality maximum. All records using the same ST-preferences. If u listen - no, ur ST is not broken, the stutter comes from my record.

Any ideas what it could be?
