Stereo Tool

I think Hans refers to an email exchange I had with him. I was previously using Audacity v2.0.5, the issue I had was that Audacity was not compensating for latency when using Perfect Declipper; I had to manually append <latency> samples to the end of the file, then declip, then remove <latency> samples from the start of the file. The current released version of Audacity (2.1.2) fixed this. I was using the stand-alone declipper, and haven't tried Stereotool yet. This makes me curious to check it.

One thing I did discover: don't turn off the clipper GUI! The result is that Audacity tries and fails to display hundreds of rows of sliders, mostly unmarked, but a few with cryptic character strings Hans might be able to identify as variables...

Best regards,
Mike

This was about the crash in older Audition versions when there are more than 4096 sliders, which appears to be fixed in the latest version. For some reason, the VST spec only allows 8 character descriptions. Which works fine if you have names like 'Volume', 'Pitch' etc. But not if you have 2 multiband compressors with 9 bands each (Mb1B9Att would be Multiband 1 Band 9 Attack). There are more than 4100 sliders now. So, indeed, don't use that.

Pre-emphasized not visible in output levels beta 018 and 019

whats the difference between Difference and Hear ??? ie i checked HEAR at Natutarl Dynamics and sounds VERY strange...

As i understand , difference was only the current module "work" .
But the "Hear" , will be the processing all before the current module including the current module.All ahead will be "muted"

hi mike,

thats great that you are being working on the audacity bug. but there is another strange bug, together with stereotool. i posted it some pages before.
it would be great if you correct this too. it seams to be very interesting.

That makes sense. When I (painfully) scrolled to the end of the displayed sliders, the last one appeared to display multiple lines of text in rapid succession, too fast to read. I was looking for something to enable GUI again. I finally took the brute force method of deleting pluginregistry.cfg, plugins.cfg, and pluginsettings.cfg from C:\Users\...\AppData\Roaming\Audacity (after copying elsewhere of course.) The software then regenerated those files. I also deleted PerfectDeclipper.xml, which did not regenerate, but seems not essential because the GUI was restored and PD is working.

This is in the current release version of Audacity, 2.1.2.

@Mike27: The setting to enable the GUI again isn't even in that list! That's a setting of Audacity, not of Stereo Tool

Fixed:
- 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)

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 01-020.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 01-020.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 01-020.dll

Known issues:
- 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
- Paul Kriegler send gui
- 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.
- Make better resampler! Test correct direction! Factor = input/output
- Make new separate Presets class
- Split presets in repair/process
- Check that FM output can still be L/R stereo if Stereo/RDS encoders are disabled
- 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 DISABLED display
- Generate UIDs and use link
- Password for login?

DONE:
- 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.

Shouldn't that be beta 20?
