Stereo Tool

One of them.

I'm still voting for fixing/redoing something (Hans knows) within the control circuit of the "Digital" (multi-band/single-band) compressor, which would also improve Natural Dynamics detection (but that's eventually getting redone).

I've been working on a new update for the Minnesota presets, and it's just the "North" version that will continue from now on, simply as Minnesota. It's sounding better than ever in the testing so far. In general there's less range within the multiband, which removes some of the spectral balancing ability during extremes, but it also has less of the Digital mode compressor's inaccuracies (about half compared to what's public). It's considerably more open when it should be, but can still adapt extremely quickly (faster than you can hear) when it needs to. Currently working on stress-testing the new AGC settings.

It'll be the last public release of Minnesota until the Digital mode multiband is fixed/redone, at which point I can start working on the final version of it.

If that update effects Natural Dynamics, or when there's new dynamics detection being worked on for that, you can bet I'll be testing that and working on new settings for it.

That's pretty much the point where I'm at, too, Jesse.

I've published 0.09 of ElevenHeaven to Hans and on FB. It is a pop preset and I think it's gone as far as it can.

I know Hans is working on some things we've all been requesting. When those are done, it will not be a drop in fix. I will have to completely rework my preset. That's a chore I will be more than happy to undertake. Until that time, I believe I've produced the best preset that can exist given the vision constraints I've placed on this preset.

I'm extremely happy with what we're able to produce thus far and very grateful to Hans for his excellent strides in this release.

I'd like to thank Wes also for his preset which I have been testing since 0.07 on our little LPFM. We're 50/50 talk and a wide range of Christian music - everything from soft CCM to hymns to classical to Americana.
Seems to be a good all around preset to these ears.

Thanks! I love the feedback. This was a fun exercise.

As above. Getting the same. It does restart but of course interrupts program.

Hm, unfortunately it turns out that the exception address is inside an Intel library function - I have no way of seeing how it got there. Paul, did you have the same address? Does either of you have a way to reproduce this issue?

Edit: I have just found a bug that could cause something like this, but only on preset switching. I found another that could occur when no FM output was selected. Did you get this exception when changing settings or just when audio was running?

I will run a new build in about an hour with these 2 fixes.

Hi Hans,

For me all I did was start ST and that happened.

On restart it has never happened again.

C.

Fixed:
- 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.

Windows 32 bit:

Winamp DSP: http://www.stereotool.com/download/dsp_ ... 01-021.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 01-021.dll

Known issues:
- 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.
- 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.
- Make new separate Presets class
- Split presets in repair/process
- 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...
- Add agc drive
- Generic plug-in (not posted) FM output to host doesn't work.
- Thimeo.js add DISABLED displays
- Generate UIDs and use link
- Password for login?

DONE:
- 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

Later:
- Perform latency measurements
- 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.

Why i don`t see from where to set the Quality >100% ? My slider is still max 100% - Stand alone.



EDIT: Found exception error when i set AGC to 1.00:1 - it acts like turned OFF, but if DB style is enabled , it shows the error.
If i disable the DB style, i can close the exception window.
Edit2: Gate indicators in AGC main window are not working (not moving) like in the main ST window indicators(above scopes).
