Changes/bugfixes

• Parametric EQ updates were broken.
• PiMP showed AGC stereo settings in menu, but does not support stereo.
• STudio crashed when started without a settings file.
• Fixed a warning (didn't break anything) in the web interface.
• New Raspbian version requires explicitly calling jackd with 2 input and 2 output channels. Firmware update has this; new Pi 5 image will use that.
• Pi 5 image works! To be uploaded after 10.41 release build
• Web interface indentation is missing.
• ST-Enterprise: Web interface instance links don't work for non-GUI runs
• ST-Enterprise: Disable error/warning popups of instance in Overview screen
• Web interface could enter error state if widgets were outside of the visible area after loading a page.

TODO's

• - posters -
• AM Brilliance: Make filter to compensate for phase cancellation at lower Quality settings
• Split AM Brilliance into a normal Brilliance for processing and a separate one for AM? Wait for feedback. (Was: How do we enable AM Brilliance for AM stations? It's basically a processing setting, or should we move it?)
• AM Brilliance: Try minimize add filter
• AM Brilliance: Try LPF before MB, directly after (or part of) AM Brilliance
• Check VST3 crash on Mac
• Check VST2 Perfect Declipper VST in Reaper, report that 64 bit doesn't work, 32 is fine.
• RIST support for MicroMPX
• Wrong page is loaded in ST-Enterprise after startup
• NAN's show up sometimes, why???
• 32 bit CortexA53 old GCC version for GA
  -
• Can we use USE_COMPACTED_STORAGE by default? Would save a lot of memory.
• MicroMPX doesn't show EF mode error in Stereo Tool plugin version.
• MICROMPX VIA TCP FOR STARLINK - SHORT 1-5 SECOND DROPOUTS WHEN SWITCHING TO ANOTHER SATELLITE. Or SRT.
• CLIPPER - USE HIGHS TRICK ON VOCALS, ALLOWS SPEAKERS TO BE DRIVEN LOUDER?
• < 150 Hz mono to remove rumbly on vinyl.
• Insert points: Via the sound card to outside and back? Or via VST's. To enable adding effects.
• Vinyl click detection and removal.
• Report that VST3 on Mac crashes on startup
• Audio I/O -> Synchronize: Sommige meters zijn 2x zo hoog als ze zouden moeten zijn.
  -
• Website: Write description of how to set up ST + MicroMPX, seems to be difficult for some people to find.
• MicroMPX multicast issue directly after startup
• Add loading presets via JSON (nrk)
  -
• Finish US pricing, update prices.
• MicroMPX overview app
  -
• When sound card/stream recovers after error, clarify current message which appears to indicate that it's not streaming at all.
• Remove Stokkemask Clipper?
• Remove Simple Clipper from STXtreme
• Phase Delay isn't disabled at low latency settings, causing extra delay.
• Soms geeft "GetSamplesScrollSize" -1 terug, omdat scrolled[index] 0 is. Dat wijst op een issue met updaten van de waveform op momenten dat dat niet nodig is. Op dat moment doet 'ie dus onnodig een volledige redraw. In debugmode gebeurt dat vaak.
• MicroMPX GPS: Extreme amounts of logging when GPS data doesn't come in due to bad antenna. Causes disk to fill up in a day, so the logging cleanup also doesn't help.
• LiveWire 48 kHz FM output doesn't work with ASIO
• Enabling Parallel MB's sometimes hangs (deadlock in Sync code?)
• Streaming: Add FLAC support
• SFN via NTP: Waviness every 5 minutes and long periods.
• Test SDI
• Get rid of old presets (console)
• GUI: Sound card buffer slider behavior
• Verify that inputs 1 and 2 have separate tilt corrections.
• Analyzer
  -
• MicroMPX via TCP should be simple now, but might require some redesign...
• Mac AU plugin should be easy to make now
• Create small program to send UDP or TCP commands for UECP. Maybe even real UECP commands... Could be the start of a new product For now, ncat works (example: echo PS=Hello | ncat 127.0.0.1 4001), see https://nmap.org/download.html#windows
• I/O: Add file input (and output?) so we can use files as backup material. Maybe both let it run all the time or make something like in MicroMPX that only plays when needed and pauses in between.
• I/O: AES67
• MicroMPX: Make readSlidingWindow smarter; only copy if necessary (lazy).
• MicroMPX V5: Add L/R peak levels to encoder and decoder libraries.
• MicroMPX V5: Simplify header structure
• Add test tones to check phase and level issues for FM, like in old calibration.
• Fix stepping of sound card buffer sizes (without control/shift should be 1, not .1 or 10).
• Add RDS2 slide shows
• Check report: Generic plugin crashes on mono input
• Multi-line translations fail (.stl): Fix reading
• GUI: Don't show 2nd channel for mono processing
  -
• Check compressor warning (or later)
• Delay issue in MPX display; not synchronized with the audio.
• Overview screen password protection: How should that work?
• Overview screen: Error should be shown here.
• Advanced Clipper: Check and improve filter-vibrations code. Also make it for mids.
• Mono bass for HD cannot be enabled without enabling the other "Reduce stereo" settings as well; needs to be split off just like for FM.
• MicroMPX: Somehow detect and report number of incoming streams
• Do something to draw graphs even without audio
• Pragma messages: Check and remove where possible
• Check BIMP meter bar; dynamics section MB on/off removes top bar
• MicroMPX: Add error checking for IP addresses, don't open if the address isn't complete. (Maybe wait for ENTER? - Web interface).
• Figure out which settings to put in overview screen
• Mac: If the sound card doesn't exist on startup and you try to close, nothing happens. Then attempting again crashes ST.
• Improve sound card error messages on STXtreme
• Pi 5 version doesn't detect HifiBerry. -> Adding ,slave helps, but for which cards is this needed? Ask HifiBerry -> https://support.hifiberry.com/hc/en-us/ ... 4212871453
• Run Valgrind on multi-instance.
• MicroMPX: Extra priority setting for during startup.
• Think about MicroMPX post processing performance. Is anything possible here? Just 2% less would probably be sufficient... Maybe remove scaling? -> No; no effect. Maybe do initializing at prio idle?
• MicroMPX: “umpxDecoderGetStreamFeedback()”: the signal lost counter in umpxDecoderStreamInfo seems to be stuck or sometimes not to count up when there is no input (with pilot generation active, internal sync turned off). I can’t rule out the problem is on our side, but it was working before and I think we did not change anything handling the umpxDecoderStreamInfo.
• Manual?
• Streaming must read data from files from a separate thread, https://forums.stereotool.com/viewtopic.php?p=75718
• Can we add an automatic gate for Blue Monday? Detecteer harde tikken die even hard zijn als input maar toch steeds harder worden en te hard zijn.
• STAMP license error message is only visible in the native GUI (which doesn't exist); how do we show it in the correct GUI (the one in which the button was clicked)? Same question for overview page.
• DHD: Remove logging, probably.
• DHD: Add FM Professional to purchase options on the site.
• Fix Declipper issues reported in https://forums.stereotool.com/viewtopic ... 4&start=30 and on Discord
• Restart when sound card does not work is not working anymore
• Some complaint about RDS in 10.20, https://forums.stereotool.com/viewtopic.php?p=75314
• .st.gui_override does not survive firmware updates in SD card image; needs to look in root directory.
• AES67: If a LiveWire port is selected under "Device" but nothing is detected there, that port number overwrites the active port field on preset loading. The pulldown itself cannot be changed if nothing is detected.
  -
• Advanced Clipper: MAYBE make a filter that limits how much bass mids and highs protection can remove at the most. Can be done later.
• Does Blue Monday with new compressor get better if I slow down reference release?
• AGC: Most likely we'll also need to change the release behavior compared to the compressors.
• AGC: Bojcha: Some other stuf really needed, - startup level - return to platform - gate after agc (please) - some sort of compressor or some protection for bursts like on old AGC - why freeze is not fully freeze (there is delay)
• MicroMPX: Run as service?
• Update clipper, optimize for new compressor
• Preset exporting: Auto-fill file name.
• Web interface: 2nd meter bar color is always orange, but must be less bright version of main color for input gain, MPX out etc. - Waiting for web interface update
• Loading a Stereo Tool preset on PiMP also sets things like whitelist, blocking access.
• Make RDS/RDBS selectable or something, independent of 50/75 us pre-emhpasis.
  -
• New compressor: Matrix mode: Limiters work on L+R and L-R, instead of L and R. That's probably bad.
• MicroMPX: Allow RDS settings in library?
• PEQ in MicroMPX FM output?
• VMware licensing 2w
• M. mails! + Contract
• Sensitivity scrolling vs sliding
• MicroMPX: Check pilot cleanness in decoder if pilot frequency is slightly off (19005 Hz).
• Add capture output soundcard??? (Wasapi loopback?)
• Web interface: MicroMPX decoder display "ports" field gets too small after switching to another tab and then back, with a relatively small window. https://forums.stereotool.com/download/file.php?id=5827
• Also, I notice when adjusting the buffer, there's no way to adjust by 1ms. There's 0.1ms (CTRL), 10ms (SHIFT), but it doesn't go by 1ms when no modifier is held. It would also be very handy to have the Synchronize with HD slider in between the HD and FM output cells instead of hidden in the More FM Output Settings.
• Reset skin, and other things (basically anything that can be loaded?)
• Pi: Make network settings changeable via web interface.
• Startup delay on MicroMPX?
• Upload SD card image updater somewhere
• Update LiquidSoap links
• mndxer1049: Better Natural Dynamics section with WB dynamic detection
• mndxer1049: A very transparent, C-Level like new AGC design
• mndxer1049: Auto Stereo Pilot
• mndxer1049: Maybe: A button for putting all CPU settings at the maximum value and turning on all CPU intensive settings that only improve audio, but take quite a bit of CPU load. (ex. sliders like ‘Quality (increases CPU load)’ under DeClipper restoration, “Strictness (CPU)” and “Leif’s highs gap protection stages (CPU)’ under Clipper just to name a few of these ”CPU sliders” I’m referencing.)
• Display bug in MPX display (weird spectrum glitches that occur occasionally)
• Add streaming output to VST version?
• In the audio input section I'd like to see options for speakers to be included without having the need to use virtual cables to route. I was thinking something similar to Rocket Broadcaster. There's input for mic and separate application source.
• MicroMPX decoder: High frequency tilt correction is performed BEFORE data is collected for display, looks like overshoots.
• Auto pilot
• Redesign ND dynamics detection
• Maybe add some frequency display to MPX display. https://forums.stereotool.com/viewtopic ... 16&t=33720
• Remove 45 degrees angle in gonio meters https://forums.stereotool.com/viewtopic ... 16&t=33699
• Add numeric displays to ITU and MPX levels in GUI https://forums.stereotool.com/viewtopic ... 16&t=33686
• Insert/delete bands in multiband compressor, instead of (like now) just having to add/remove the last one when the number of bands changes.

• libVLC with FDK???

The enabled state issue in the VST from 1040 isnt entirely fixed yet. It'll show the enabled modules upon loading the GUI. However, one has to close the plugin and open it again to see any changes.

For example, I load up a fresh plugin with no ini. It starts on ABM, which has no Declipper enabled; so I enable it. However the scopes (or other changes) don't ever show up until I stop the plugin and load it up again.

OBS, vst2x64, 1041-001

This is no longer happening for me in OBS as of 10.41-002

Newly licensed user here, running this beta on the bench while preparing to put this on the air.

I was tinkering with some additional features I didn't have enabled in my "optimum" preset and turned on natural highs. I noticed that no matter where I set natural highs to be in the chain, the GUI is displaying it after both multibands (the spectral display).

So the question is, is the location not changing, or is it just that way in the UI?

Absolute Highs? Correct, the UI doesn't update to show the location of AH. However, you can tell it has moved by watching the in and out spectrograms if you also have the Highs Exciter enabled. Place the Highs Exciter between the multibands then watch the input gram on Absolute Highs while you move it before and after the multibands.

However, it would be nice indeed if the metering on the overview page updated to show the location of the modules. I'll ask about this.

You think about µMPX over TCP, why not use SRT instead, as already requested here:
https://forums.stereotool.com/viewtopic ... 16&t=31044

That'll solve all sorts of scenarios where you can't push µMPX to a fixed IP address or where you have more than x transmitters using the same µMPX feed.

Given the "success stories" I've heard about SRT it might as well fix the Starlink problems.

AM Brightness:

Started using it today. So-far, very impressed!

And SRT would provide compability to the 2wcom MPX Decoders.

Does SRT give us everything that TCP gives us? Including going through routers, dynamic IP addresses at the receiver side, etc? If so, then this would be the much better solution indeed.

Yes, yes and yes. In case you have a dynamic IP at the receiver site SRT will establish the connection for the receiver site. SRT is UDP based but all the features you expect from TCP and much slimmer. Packageloss of ~5%? No problem. I use StereoTool with µMPX over SRT using local srt-live-transmit command line tools to pipe UDP into SRT and vice versa. Runs like charme. And you have nice stats about the connection state on both sides as for retransmitted / Lost packages. Great for monitoring, like here in Grafana
