Stereo Tool

This crash was only once, other situations with not responding icon or blank window but with processed sound from VLC, so I'm confused about it.

Bug: When "Rules are there to be broken" is enabled with Maximum Asymmetry set to 100%, the L/R output meters will often show red, even though Hard Limit is enabled.

It appears that Maximum Asymmetry can be run up to about 90% without any trouble. Past 90%, increasing amounts of red output will be observed.

EDIT: As soon as I hit Submit on that, I started observing the red condition as low as 50%.

EDIT2: I even see the red display when running at default 10%. Disabling it for now, since I'm not sure whether the bug is UI only, or it is affecting audio.

Not sure what that is, I don't think it will cause any problems but I'll check it.

If you get a not responding icon there should be information! Which usually shows where (.exe or .dll) the crash occurred, if it's in VLC it should say something with libVLC.dll. Can you get that info? It should also be stored in the Windows event logs (which are located in a different spot for each Windows version so I can't really tell you how to get there; it should be in the 'Applications' log). If it does NOT mention libVLC then the crash address and code would be very helpful).

And, this happens all the time when you press BYPASS? If so, can you check with normal sound card input to see if it still happens then?

Not sure if this is a bug, but I noticed that in HD mode there are spikes on the output analyzer, in FM is it perfect between the lines.

You're probably not using the oversampled clipper (you can turn that on in the 'Limiting & Clipping' panel). The scope *is* oversampled.

Unhandled exception at 0x0103C2A0 in StereoTool.exe: 0xC0000005: Access violation reading location 0x000000C0

When clicking Low latency output

Confirmed! Looking into it now.

Fixed:
- Make new separate Presets class ->
- Check and solve Linux Valgrind errors for Declipper
- Linux high CPU load
- Solved Low Latency mode crash

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 01-028.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 01-028.exe
Windows VST 32 bit: http://www.stereotool.com/download/vst_ ... 01-028.dll BUILD FAILED - NOT AVAILABLE

Known issues:
- 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.
- Linux Rivendell version -> Returns silence in FM output, why??? Add logging!
- Kill License SST
- Run Valgrind for MicroMPX
- CHECK CRASH with VLC - VLC related??[/color]
- Linux Fedora issue

DONE:
- 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

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.

I feel like maybe I didn't get enough caffeine this morning. I don't see anything new with presets in beta 28.
