I agreed with you in advance. ;)
If that's true then "Maximum Gain" (wich is basicly AGC drive) in Omnia.9 is working wrong.
I wouldn't expect Maximum Gain and Drive to do the same thing. In processors I have seen that employ a Drive control, it is simply an amplifier immediately before that processing stage. Or at least that is how it appears to function in processors I have dealt with.
Leif's "Maximum Gain", and Hans' "Drive", do not operate the same way.

Leif's actually has a real 0dB which everything is centered around. As long as the bands aren't running out of range, and you're not using progressive release, you're free to adjust the Maximum Gain setting, and there will be NO change to the audio. Even with non Infinite:1 ratios. Similarly... adjusting the ratio of his AGC (or "a band") that's at 0dB will have no effect on the average loudness of the audio at that given moment.

Hans' AGC and multibands have 0dB at the top, so changing the drive will change the sound if there's a non-Infinite:1 ratio being used. There's no way around that, without copying what Leif did.

Good video, nice to see interest in bandwidth limiting.

I would like to see some way to manage stereo width in ST / SST at least with 2 frequency areas, below and above 700 Hz.

[edit]
Actually... I did figure out a way to get closer to what I want to do with the stereo image. It's attached. I need to work on it more, but it's not bad so far. :) It would be better if ACR was just capable of limiting the amount of total stereo output in at least 2 frequency areas... vs just having control over what's being added and just broadband... since I don't like "stereo boost" as much.

Well, it would be nice to have graphically controlled stereo width, in the same way as eq or phase shift. With range from total mono to wider stereo (200%? 400%?). I miss this option a little (i like "center bass" and slight widening around 2-4kHz, but not widening "sparkle" above 10kHz)..

Fixed:
- Matt/Joop barrel shape thing: Split Ratio into Start and Maximum Ratio. Note: I don't know if this is good or not yet. I added this feature after talking to several people, and on one hand it seems to make sense (in dynamic tracks, short quiet moments will get louder and short bursts will get quieter), but on the other hand it might also be bad (making the loud bursts quieter might make dynamic tracks sound softer than non-dynamic tracks, which is the opposite of what we want). Waiting for feedback, if this is bad I'll remove it again. Note: With setting lower than the Start Ratio (for example the default value of 1.00), the Maximum Ratio is ignored.

- STAND ALONE VERSIE in SST mergen
- Als saved en Load onder All Audio setting dan is Over Sampled Limiting and Clipping uit geschakeld -> Seems to work as designed (which is different from before though). -> Changed back for Stereo Tool
- Sync: Handle big difference between clocks. More than .01% is probably already too much. Then ignore. Add a parameter, set to 0.1%.
- Crash reported by Wouter Tietema, probably caused by low latency monitoring output. - probably fixed.
- Sync: Was adjusting new constant offset from Normal to FM output in wrong direction.
- Edit: I see occasional jumps in the output VU meter. They are *not* present in the scope or in the sound card output. Will check.
- Stand alone HTML5 GUI FRIDAY
- Linux Fedora issue
- Make MAC version HELP work. (tonight) - to be tested
- Remove LQLL HQ mode (non-SST) (tonight)
- Check VMware flag turning ON for unknown reason (tonight) -> Not changed recently, and seems not to cause problems, so ignoring for now.
- Fixed synchronization problem between meters, scropes and audio
- INDEX.HTML automatisch resolven
- Add no cache to objects.js!!!
- Declipper broken according to DJ_DOGGY, so far unable to reproduce!
- Change version number
- Crash in BETA029 fixed.
- Linux Rivendell version -> Returns silence in FM output, why??? Add logging! --> _ST_AUDIO define! But why does it work in Windows?
- Kill License SST
- Remove warnings
- Check red output bars for 'Rules are there to be broken' - overshoots and clicks present.
- Generic plug-in (not posted) FM output to host doesn't work.
- Make new separate Presets class ->
- Check and solve Linux Valgrind errors for Declipper
- Linux high CPU load
- Solved Low Latency mode crash
- Previous version could crash on startup. Should be solved now.
- Thimeo.js add DISABLED displays
- Test if clock moves in right direction (that could be the gaps that are reported) --> Clock jitter calculation effect removed for Stereo Tool (not for MicroMPX). I hope this fixes the issue. Waiting for feedback.
- White list IP's?
- Absolute Highs display broken. Only in HQ version. -> Weird only on Koek pc. Check tomorrow. Ah, only weird if there's real audio, not on background noise there. Maybe stereo effect? Still unable to reproduce on my pc... Copy settings. -> Was clipping in the Winamp output which was fed into VAC. Enabling the Declipper made it a lot better!
- Add agc drive, remove Pre Amp (not remove, default is already 1, so never mind).
- Show link to web interface, hide everything else! (Password)
--> Clock jitter calculation effect removed for Stereo Tool (not for MicroMPX). I hope this fixes the 'gaps' issue. Waiting for feedback.
- Crash reported by multiple people fixed.
- Claimbigf failed once ("Claimbigf failed: In use!") -> Added extra checks, should warn if it happens again. I'm guessing it was triggered by some other bug. --> Was caused by crash
- Split presets in repair/process
- VLC Input broken (resampler is BAD, should probably be disabled in this case?) - Also sound cards should collect MUCH more data before starting to resample.
- Turning pre-emphasis on/off give a big glitch! - Was caused by Phase Delay time shift triggered by having 'Ignore high frequencies' on.
- CPU load: Test if it's indeed lower in 021. Quick test: 45.5% to 44.8%. So, yes.
- Check that FM output can still be L/R stereo if Stereo/RDS encoders are disabled -> No. Needs to be fixed. -> Does what it should do now.
- Fixed some potential crashes - not sure if the one that was reported by 2 people is included
- Make better resampler! Test correct direction! Factor = input/output
- Quality 100-110 is not great, rest is.
- SSB DSB mode in enum, check if it works
- Enum 50/75 add OFF, encode Mu as non-HTML mu
- Add Declipper main view
- Bad pilot/RDS at certain Quality settings, only if Threads==1. Seems ok at high Quality settings... Different in HQ and non-HQ builds. Ah no, sometimes also at Threads > 1. Display only though. Ah, happens when Normal output buffer <= FM buffer size and FM output is disabled but I am displaying FM output. Must be looking to close to the point where I'm writing in OldSamples. (Correction for Normal Output is applied to FM output, probably?). O :( Caused by synchronization issues between threads... And at different numbers of threads everything is broken (note: Only scopes... but all of them!). I think we need a position in the display per thread index to solve this. Then the existing code might work again without changes. (Except that it needs to be triggered from the Framework thread).
- Weird time shift in bottom waveform (or in top waveform?) they don't stay synced at 10 second view size. -> Fixed with bad pilot fix
- Problem with threads is fixed, but still needs to be synchronized with the rest of the GUI and sound card (too much delay now on scopes).
- Phase Rotation before/after doesn't update
- FM Analyser was broken -> mostly fixed, some glitch still present after sound card restart on 2nd channel. -> Ignoring for now...
- Add Delossifier difference, also for Stereo, True Bass & Absolute Highs & Bass Boost, add Declipper, Equalizer, Bandpass, Clipper -> No, only Bandpass and maybe Clipper.
- Smooth preset switching: No more hiccups (if the same filters are enabled) and also faster.
- Quality between 100 and 150% improved (around 101-110 not great yet)
- Connection lost issue web gui
- Add window to AGC (wednesday)
- Make 'HEAR'/'Till here' work (wednesday)
- Test tones are broken (wednesday)
- Make output waveform visible again for non-FM output. -> Appears to be ok now.
- OS_COPYTHREADPRIOTO(td[ch].process_thread) (wednesday) - Was already ok
- Display CPU usage for LQLL threads (tuesday)
- Set affinity for LQLL (tuesday)
- Display needs to be updated for all processing threads (tuesday)
- Display updates must happen in correct order (weird noise jumps otherwise) (tuesday) -> No, was related to updates for all threads
- Don't calculate FM signal if FM is disabled (causes extra display in output too) (tuesday)
- Large pilot phase difference found (tuesday) Fixed with workaround. Reason still unknown.
- AGC gate in bars like compressors - now also in the normal versions
- Displaying CPU usage for all (primary) cores if you select more than 1 thread.
- Reduced memory usage to below what version 8.00 used!
- Gain works again
- AGC gate in bars like compressors
- Low Quality Low Latency monitoring (stand alone version) is working again
- Restart server if all clients are full for a while?
- Delossifier web display added
- Type IP in web site
- Quality below 100% in HQ build error

DONE IBC:
- Email NAB visitors
- Images for booth presentations Mathijs
- Images for ST presentation
- USB sticks!!! ORDERED ARRIVED
- Business cards Matt ORDERED ARRIVED
- Call Karlex CALLED, WILL BE SHIPPED.

Later:
- Update website LATER
- CHECK CRASH with VLC - VLC related?? Not seen anymore, later.
- Perform latency measurements
- Web interface export preset
- Generate UIDs and use link
- Password for login?
- Attempt Wes Keene's Feedback mode (see Facebook chat)
- Auto-determine best latency/affinity settings
- New idea: FM stereo trick might reduce MP3 artifacts as well! So add it to streaming output.
- Run as a service
- TODO: Add exception if ignoring too high VST parameter numbers (Audacity bug! -> Was fixed in later Audacity version, never mind).
- Websockets? Later
- However, MediaMonkey was quite insistent I upgrade to the later version 4.1.13.1801, so I did, and now what is happening is the Declipper screen is whited out and can't be configured, though it still works with the last set settings.
- Also when I close MediaMonkey, the Declipper screen hangs (everything else closes), and when I do a forced close, Windows says it's MediaMonkey hanging.
- Still a hack (enabled with a special setting) is needed for some people who want RDS with stereo output... It doesn't make any sense but on some transmitters that apparently works... However I only know of one person who uses this. Not urgent now, this person can use an older version for now.
- Remove inputOldSamplesFixedCopy, should not be needed if I split WAVE from VU meter calculations.

What about "Stereo Image" > Center bass.
Result which i hear is so "cold". What about new feature?
I want to choose mono freq range and slope.
Maybe you will add this feature in future?

Sorry for bad english.
Best regards,
Ilia.

Quality up to 100% will be possible at some point?
The preset "Eleventh Haeaven" sounds great to 120%, but there are some small jumps in some songs

Are you running StereoTool or Omnia SST? Values greater than 100% are not supported in StereoTool.

I'll let Hans come in here and educate further, as he desires. But I would not recommend going into a text editor and kicking that setting up any higher than 100%. Not only will it not work, but it might have negative consequences such as the one you've observed.
