Changes/bugfixes

• MicroMPX: Check GPS mode on Pi, apparently broken - No, must be user error - LEFT channel still contains correct audio, right is latency loopback tone.
• Very scary fix: A tilt correction mask was being calculated using the first latency seen after startup, instead of the current latency. Could cause extremely weird behavior. This bug must have been there for years, but would be mainly noticeable when mixing multiple latencies in multi-instance.
• STXtreme: Keeps nagging about deprecated settings after restart?
• Mac streaming was broken (in 10.41, so basically always)

TODO's

• MicroMPX: RIST mode 2 and 3 didn't work from Stereo Tool
• STXtreme: Added loopback I/O board self-test with auto-reboots for station with power stability issues.
• MicroMPX: Add missing average bitrate display for stand alone (non-library) version
• MicroMPX: Add total bitrate display (does not take RIST overhead into account)
• MicroMPX RIST: Try to work around crash deep in librist: RELEASE was missing, causing memory leak!. New test running.
• MicroMPX: When disabling stereo encoding in Stereo Tool, the integrated MicroMPX encoder is still told that there is stereo audio. Which probably means that the clipper is running in stereo mode as well, which is also wrong.
• MicroMPX encoder: GPS checkbox doesn't get disabled when GPS signal disappears. And GPS will keep sending forever, which is probably bad. -> Does not reproduce here. Some GPS encoders may keep giving time stamps with no signal, maybe that's what happened?
• Added fix for testing; remove and delay if it doesn't work.Seen in LiquidSoap on Linux: Stereo Tool generic plugin uses host application name instead of its own name, so it saves under .liquidsoap.presets for example. Might not be so bad; running it in different hosts gives us different files. No current hosts on Linux support more than 1 instance I think.
• Decide whether to keep or remove "Smart bass clipping (TEST)". -> REMOVED.
• MicroMPX: Reduced tracing context from 512 to 128 lines
• MicroMPX encoder: RIST: Added 15-second recovery buffer (hard coded)
• MicroMPX decoder: RIST: Add confgurable recovery buffer (how?)
• MicroMPX decoder: RIST: Fix crash when blocking callback during switching between inputs
• MicroMPX decoder: RIST: Figure out way to get rid of RIST delay, or how to sync with non-RIST and how to specify RIST vs non-RIST delays
• Matrix mode: Make a setting to never reduce stereo - Wait for feedback Mathijs
• Finish Declipper plugin
• Multiple streams: Report that only 1st stream has metadata (strange, waiting for confirmation).
• STXtreme: Implement smart glitch detection INTERNALLY so we don't need to run external tests all the time. Maybe we can already see it!
• STXtreme multi-instance hiccups system Matt - why?
• STXtreme: Audio seems fine even though buffer display shows that the buffer is very low.
• STXtreme 5 FM instances doesn't work if more than 2 are set to latency 128. Do more measurements and figure out what the limits are.
• Flights + location Vegas
• Check Norway, book hotel/flights
• Mac version leaks memory, at least with GUI minimized. https://support.thimeo.com/scp/tickets. ... 3193#reply Tom
• MicroMPX: Export the control signal that would control when the backup player becomes active to the JSON and library outputs so GPO's can be coupled to it.
• Check VST3 crash on Mac
• Check VST2 Perfect Declipper VST in Reaper, report that 64 bit doesn't work, 32 is fine.
• MicroMPX multicast issue directly after startup
  -
  When RIST works:
• MicroMPX support multicast IP and NIC selection via RIST??
• MicroMPX: Add/modify JSON parameter that shows total used bitrate to include RIST, plus number of RIST clients.
  -
• Upload new manuals
• Update MicroMPX manual for RIST
  -
• MicroMPX: Add way to set IP address of hardware
• Multple streams: Support different metadata??
  -
• Would it be possible to make an R128 measurement there, where I can set the measurement period for a sliding window between 1 and about 5 minutes?
• MicroMPX: Reduce RIST overhead
• Clipper + Hard Limit makes the spectrum dirty, mainly for pure sine waves - but why?
• STXtreme: Add loopback test for handling brief power drops. BUSY
• MicroMPX library: umpxDecoderDecryptAnalysePacket may try to decode a packet while internally a packet is already being decoded, causing threading issues.
• MillingBroadcast's MicroMPX speed issue with encoder in Stereo Tool on Linux: https://forums.stereotool.com/viewtopic ... 454#p77454 - Waiting for feedback
• Silence detector in ST with email/SMS?
• Bojcha (via Discord personal chat with images): Clipper (measured HD out, no pre-emphasis) has HOLE between 5kHz and 13kHz about 0.4dB. Only way to fix it is to set Highs clipping from +1.51dB (default) to +0.95dB. He says it sounds better too... (less gaps due to highs, not less highs)
• MicroMPX: Add GPS support for decoder without NMEA. That's how others do it - they just use the timestamp in the packet as the time of the closest 1PPS pulse. Will simplify the hardware!
• MicroMPX: Silence detection in MPX is used to switch between studios! So reporting levels is really necessary.
• Mathijs: Als je de AGC in Matrix mode gebruikt (trouwens voor MB hetzelfde denk ik), dan wil je eigenlijk channel linking gebruiken om te voorkomen dat L-R heel extreem bijgetrokken wordt tov L+R. Alleen: als dan de hoeveelheid stereo content flink toeneemt kan het zijn dat L-R de L+R mee omlaag trekt, en dat wil ik eigenlijk niet. Dat gebeurt sneller als je ook nog die "Stereo boost when AGC is below threshold" setting gebruikt. Zou fijn zijn als die channel link maar één kant op kan werken; dus dat L+R altijd vrij kan bewegen en dat L-R daar aan vast gelinkt hangt
• Vinyl bass rumble removal
• 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.
• < 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
• Sound cards: Add VLC to input 2 for backup - but that requires a fix for when the stream drops out.
  -
• Website: Write description of how to set up ST + MicroMPX, seems to be difficult for some people to find.
• 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
• Streaming: Add FLAC support
• Test SDI
• GUI: Sound card buffer slider behavior
• Verify that inputs 1 and 2 have separate tilt corrections.
• Analyzer
  -
• 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
• GUI: Don't show 2nd channel for mono processing
  -
• 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.
• 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).
• Improve sound card error messages on STXtreme
• 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.
• 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
• .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.
• 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?
• 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?)
• 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?
• 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
• 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.

• MicroMPX: Show temperature
• MicroMPX: Show status per incoming port
• Win10 scheduler appears to ignore ideal CPU cores since last (few) update(s)

• When audio has run after a settings change, trigger a parsetChanged
• Time offset on STXtreme, for RDS (also for ClockTime!)
• New GUI: Support smaller monitors (smaller default size, especially for VST). Contact near05.
• Export presets from web interface needs filtering, just like from native (so the code is there! Just reuse CopyPresetOm*).
• Mac: VST2 sizes
• Mac: gavinmcgrath: "Intel MacOS 11.7.3 in Wavelab 11.1: Blank screen." https://forums.stereotool.com/viewtopic ... 407#p73407

  -
• Add check for running ST multiple times; make switchable if we want to allow it or ask if you really want to start if it already runs or something.
• Matt: Pre-emphasize highs slider needs to get a clearer description! Something with avoid overshoots. Basically a sidechain EQ. "Add highs to sidechain".
• Matt: UECP must be more easily accessible, too deep now.
• Matt: FM+AM
• Check EQMB_SCOPES
• New I/O framework: Add extra latency to plugin input so the input 2 to LQLL can be instantaneous.
• Check Bojcha's good bass HPF settings (18200 Hz, ignore high frequencies, 48 kHz, 35 Hz HPF)
• libVLC with FDK???

Suggest that the indicators for Intellelimit in multibands use the "Light accent color". They appear to be hard coded as white currently. When a white background is used, the display shows no action.

Thanks to MrKlorox for the tip!

Hello Hans, is it possible to turn on the settings full settings of the adaptive compressor "Multiband2" it gives a more flexible mid-bass. The sound in "AM Brilliance" is almost perfect at the highs, (I feel a more detailed effect).

Once upon a time in assemblies with parallel compression it was enabled, there you could choose a full-fledged one

Oh, isn't it? It should be! Chekcing...

Edit: I think all the settings are there - what are you missing?

Thanks, I reinstalled the application, and cleared the folder with the old presets and VST-plugin and everything appeared (I was not attentive, there were a bunch of early versions in the plugins folder)

For the record: I filed a Liquidsoap bug since saving presets is not working when running ST from the web interface in Liquidsoap. Not sure if this is a Liquidsoap or StereoTool bug, so crossposting the reference here: https://github.com/savonet/liquidsoap/issues/4161

under the processing tab the section of levels, loudness and texture seems to be missing in the gui.

don't know if you can see the attachments but st1.png is from 10.41 and st2.png is from 10.42 beta 14.

BETA017 is posted (not for the multi-instance builds). You can now move the menu on the left to the right, or to the title bar, like it works in the web interface. The latter gives a lot more space and makes the GUI look a lot less intimidating. Go to Application settings -> Graphical settings -> Classical menu menu location.

The classical menu location is great, but I miss the volume control with quick adjustment, which I would like to see again with quick adjustment. And is it possible that the extreme tweaker can be in the menu again without the codes Ctrl Shift +

Do you mean pre and post amp? Pre amp should not be used anymore (if I had to redesign everything from scratch I wouldn't put that in). There are gain settings for the input sound card, and for AGC/multibands. And in all other processors they do the job. Pre amp basically just affects the first gain slider. (I guess there is something to say for making it available on a quick adjust page... I'll ask around a bit what others think, but generally I would argue that at least a preset shouldn't have it).
