Nice most bugs are gone but I found another one. When ignore high freq is enabled the l-r portion of the signal is boosted. And some times feeding in a mono signal generates l-r spectrum which should not happen.
When is the L-R boosted? I've never seen that so far. The mono signal l-r spectrum is normal (as in: not a problem).

The proposal me a nice sound card

I can not get the song right and left details

There is a problem, perhaps the program

little correction from me :
In "FM output" main panel there is a window with name "Output and tilted output" which is not getting alive when i press the "Generate test tone" checkbox. It enables only when enable another window (right above it). Make it this way : when i enable "Genrate tone" - the slider for frequency and the menu with the tone form to light up.

Test tone working even "greyed out" so make it like separate option for easy use.Move the displays to above window and leave only test tone in the window that i`m talking about.

Yup, this isn't easy to fix, I think I'm going to have to turn the red display off in that mode. :( I'll try if I can find a better solution but it won't be easy.

Edit: Oops, I didn't read it properly. Hm... Will check!

Edit #2: Wow, this isn't new - it's also broken in released version 7.70!
Hans, in beta 14 it works fine, even with Ignore high freqs tuned on.

Stereo Tool 7.71 BETA019

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 71-019.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 71-019.exe
Windows 32 bit VST: http://www.stereotool.com/download/vst_ ... 71-019.dll

CHANGES:
- Sometimes the top and bottom waveforms run at different speeds when Ignore Frequencies Above is enabled.
- Make Chain block (small size) based - Partially done
- Declipper display is broken. Even without Ignore Frequencies Above. Ok upto 100 ms. Also broken in 7.70!!! Only if samplerate > 48 kHz, and when switching between sizes, upto 100 ms everything is fine (even if no audio is playing so no refresh of the data occurs), so the bug is in the displaying code. -> Was a shift error, fixed.
- Turning "Bandpass" Highpass filter OFF doesn't really turn it off (!)

OLD CHANGES:
- Again, fixed noise level jumps and spike at Ignore Frequencies Above frequency.
- Clipper issues Leif / Wolf Stahl (probably the same thing) - Should be fixed now. - Waiting for reply Wolf- Check new clipper highs
- Remove "Take some shortcuts" under CPU, probably broken! And has not much effect anyway. -> Hm, no, must have been in use for the tests. Ugh... TEST to check what is better: ON (which will probably allow more sounds through) or OFF. -> Actually it does seem to work AND allow more highs through, but I don't know if that's a good thing - more tests needed!
- Added lowpass filter after clipper in non-composite mode.
- Another bug in latest beta - ST doesn't remember FM settings - presets from the fm list start up with stereo and rds encoding off
- Fix MPX display sample rate issue
- Fix Stokkemask in Leif's mode with Quality < 3
- Fixed problem with click sounds (reported by DJ_DOGGY). Reduced output level by 1% - you can safely increase modulation by 1% if you're using an output that's affected by this (should only be FM signal inside a plugin). If you're using the stand alone version, make sure to set the output level to the sound card no higher than 99% (-0.1 dB).
- Fix downsampling and Quality slider problems: Lower Quality setting
- Attempt to reduce effect on volume of using Leif's clipping method.
- Fix DJ Doggy's reported errors (19 kHz, junk around tones).
- Ignore frequencies above a specific frequency -> Should lower TOTAL CPU load by another 10-20% (now fully implemented except at lower Quality settings)
- Fixed the lowpass bug that was introduced in 009. Although it has probably always been there! As a side effect, the output is also slightly louder (about 0.02 dB) with no negative effects.
- Fixed distortion introduced in 009/010. Extra highs are still there though! See new 'Sparkling highs' section under Advanced Clipper -> Sound
- Fix optimizations
- Fix code #warnings
- Improved highs filtering in Clipper (both Composite and Normal); sound has more brilliance and suffers much less from ducking on loud sounds.
- Fix bug: NAN's can occur at certain input sample rates (40960 Hz among others)
- Fixed downsampling/resampling issues.
- Made several changes to the Clipper that affect the sound! Sound should now be more open en brighter (but it might have more distortion in some cases, I hope not though).
- CPU: Added 'Ignore high frequencies above'.
- Big Composite Clipper CPU load improvement: Added a new slider ('Oversampling Quality' or something like that); CPU load reduction is HUGE and effect on peak control (for values above 4) seems very small.
- Solved a number of warnings that I added in the last few days
- Some small optimizations
- New Highs Gap Protection improved, now similar in behavior to the old one. I had to add 1 extra step (slightly higher CPU load).
- Fixed problems in 771-004. Some optimizations are disabled - I need to fix that.
- Fix CPU measurement for high loads (jumps to 95% for unknown reason). -> Showing real average instead of median now. Median in dark red.
- Difference in measured CPU load is bigger than expected after CPU load measurement update - check why - DONE, is indeed big! Separate slider added to show both processing and total CPU usage.
- CPU: Clipper: Reduced default number of Bass Clipper steps from 4 to 1
- CPU: Clipper: Implemented Leif's mirrorring method for Stokkemask and optimized steps using Omnia interface, much fewer steps for same result.
- Added option to add a text in the title bar to easily recognize multiple instances.
- EXCEPTION OCCURRED IN HttpServer: Got unknown widget ID.
- CPU: Clipper: Highs gap protection: Use 1 step for non-FM.
- Check if COMMON_STATIC still improves performance, if not remove it -> Does not, removed.
- Redesigned parameter classes and moved everything around for integration with other products.
- Remove Stokkemask mode for non-composite FM clipper (it's probably not working correctly and more heavy than the composite clipper)
- Fixed small bug in Composite clipper FM overhead level compensation calculation. Might make the same setting very marginally louder (less than 0.05 dB)
- Fix crash reported in previous post
- Improved CPU load measurement (small part of code wasn't included, it is now).
- CPU: Composite clipper: Optimize Stokkemask: Skipping outer parts of window
- CPU: Composite clipper: Optimize Stokkemask: Fixed 'Skip smoothing' mode to be compliant, all other modes removed.
- CPU: Composite clipper: Optimize Highs Gap Protection (trick from Leif Claesson that he uses in the Omnia.9 - nearly no CPU load needed anymore!)
- CPU: Added some #pragma's to make compiler generate more efficient code
- RDS: Added some character conversions (Euro -> E, ` -> '). (not yet tested)
- GUI: Allow drawing scopes in half-height to have more headroom above and below.

TO DO 7.71:
- Synchronization is broken in 008 (was ok in 007) - Don't see it! Is anyone still seeing this?
- Change tone generation FM enable/disable and order.
- VST multiple instances fails - Tested and works fine. Ignoring unless I'm receiving a better report. Note: 32 bit too many instances can crash due to the 2 GB limit. Max number is now 3, used to be 6 so some optimization could be useful.
- Make VST window bigger
- Fixed Quality slider bug introduced in previous beta
- Fixed jumping pilot and RDS effect on some 'Ignore frequencies above' frequencies.
- Make OldSamples buffers (and potentially others) dynamic to save memory - Currently allocating 85 MB just to display waveforms!!!
- Optimize memory usage: Don't allocate more than MAX_SAMPLES_ST for blocks which only get downsampled audio. So only allocate a few things bigger.
- Fix Mac VST version (not recognized apparently)
- Fix Linux version (someone mentioned that it crashes after a few minutes, on Ubuntu 14.04)
- Add delay (in samples) for one of the two MPX channels to send audio to allow synchronization of 2 transmitters which use the same frequency. (John Markis)

TO DO 7.72:
- Add impulse response import function!!!
- GUI integration for Multiband?
- Instability in compressor behavior [WesKeene, Bojcha]

TODO:
- Noise learning Micha
- Change default preset (it still uses Classic compressor etc!)
- EQ with 'standard' sliders.
- Make BS412-like graph for levels
- Add 'warm' noise before clipper (requested by Andrew Palmquist, might help with PPM as well)
- CPU: Clipper: Optimize Advanced Bass Distortion Protection

No any change in "Ignore Frequencies above" - jumpings on certain frequency ranges is there.
Now when i enable the "Ignore freqs" , MPX spectral display starts to behave strange ( RDS is gone somewhere on right). Something like resolution change.

It`s some temporal mess with this option and the MPX spectral display.

Edit: another trick, when i enable the "Bypass" and then disable it , buffer is empty . When i repeat these steps , buffer is restarting.
And this cycle is repeating if i continue to enable disable "Bypass". Is this normal ?

Which jump do you mean exactly - I don't see any jump here except in the L-R which for composite is on purpose. For non-composite there's something there too, which shouldn't be, but that's not new (was there in all previous versions as well). Or do you mean something else?

Yes, fixed again.

No. But I just checked version 7.70 and I see the same behavior. That doesn't mean that it's good, but I'm planning a huge rewrite of the entire audio engine, so I'm not going to put effort into fixing this now.

Understand you for other things .
Now for jumping : I mean exactly the same jumping of the noise floor , that i mean all the time.
It`s still there but now is only for certain frequencies ranges . try with exatcly 16000 . Then try to slide it above 16130 or 16140 - it`s gone.

Then there is another range ( i wrote already for it on last two pages of posts) You can check my post here and focus only on jumping noise floor in that text.

If not clear i`ll make a short video ?

Post subject:  Re: Stereo Tool 7.71 BETA
I make video
Look the interesting thing. When i enter into the certain frequencies range , something is happen to the MPX scope ( pilot is moving a little , then goes back . The same thing is when i go out of this range . I found ranges from 16000 to 16130
and from 17650 to 18800. When you enter this ranges, just take a look on pilot what his is doing on video. Looks like some switching of something or entering in some other "mode" :)

On 20200 MPX scope become normal, pilot and RDS came in their places :)
