Latest version - Beta 021 (May 9 2020)


The biggest audio changes:
- Release Hold for constant speeds added
- Bass clipper filtering added. The idea here is that by limiting the harmonics that can be generated, you can push the bass clipper much harder without sounding bad, resulting in more constant bass AND a cleaner sound.


Downloads
Changes/bugfixes
  • Maybe remove release hold in peak mode? -> No
  • Natural Dynamics compensate slope steepness setting
  • Enable 2nd stage bass clipper in Asymptotic mode, and make it possible to do the filtering before or after
  • STX fix warning for PEQ

TODO's
  • STX set final fps value
  • Update DCM preset
  • Streaming: Remove trailing newline characters when reading from file
  • Update presets
  • RELEASE
    -
  • Boogaard
  • pens
  • Disable gates when switching presets
  • Added proper ShoutCast support (it was possible to use ShoutCast before but you had to fill in some things differently.)
  • MicroMPX: Removed rate limiter on/off swtich. There's no good reason to ever turn it off.
  • WatchCat: Use taglib1, which should support all ID3 text fields.
  • STX: Upload preset was hardcoded to go to 172.22.16.101 in 9.50.
  • STX: UECP settings missing
  • STX: MB and AGC meters were wider in touchscreen interface, and had a scrollbar due to that.
  • STX: Output spectrum added
  • STX: Switching AES/EBU between 44.1/48 and 176.4/192 doesn't always work, requires a reboot.
  • STX: RDS: EON, UECP and MONITORING missing.
  • STX: Shorten names, remove unnecessary duplicates.
  • STX: Metadata, Visible data, Traffic info, Alternative frequencies, Packet order, EON, UECP, Monitoring
  • STX: Re-enable ACR, including saving on/off.
  • STX: Web interface: Bug fix: Title sometimes shown in wrong location.
  • STX: Add ACR to web interface
  • SST: Multiple instances BUSY
  • Stereo Tool: Multiple instances
  • Website
  • Disable stereo widening when detecting low bitrate MP3s
  • Make final clipper (at least partially) do what Bass Clipper does, with harmonics control and Asymptotic mode?
  • Add a checkbox under Delossifier that makes Absolute Highs fix the highs.
  • STX output waveform not visible
  • STX: Verify high frequency tilt behavior
  • VST3 new NAN issue - waiting for CPU info (doesn't happen here).
  • Check Stokkemask Use Area 100% does something at input level around -80 dB.
  • Russian/Bulgarian translations don't work on 4K displays!
  • STX: Create built-in presets. Initial set added
  • Put Declipper presets in ST. Selecting one with "APPLY" overrules all existing settings.
  • Linux Jack 64 9.37 on Debian 9, stereotool shows once in main cable connector twice in the "patch pannel" is this intended behaviour? If so what is the difference?
  • Improve Advanced Limiter shape (Bojcha)
  • BS412 bug: For Quality > 100, the compressors are off by a few dB (probably 1.5x or 2/3rds).
  • Classical music preset THU
  • How to synchronize HD? THU
  • Test Framework? BUSY
  • Try immediate release combined with release hold?
    -
  • Measure HifiBerry stereo separation -> Improved from 35 to 55 dB. Make RC work with Ignore high frequencies -> Later
  • AGC classical music settings
  • Loudness project
  • Complaint: All (Normal, LL) outputs in Linux go to FM
  • Tom aan de Stegge remarks email 30 september 20:23 - change many defaults
    -
  • Support rewindowing with different Quality/Size settings. Will give better HPF performance and make lower CPU load possible, and PPM patch points.
  • Linux command line version with AES67 input so output can be streamed - seems to be useful... Other options (run a script for the output) might be easier.
  • Finish 9 - final uMPX file name issue -> In next 9 update.
  • Figure out how to display NMEA/pulse status in GUI. -> Waveform and jitter-view for pulse detection in detail view, GPS in stream, NMEA data, NMEA readable, Pulse detected flags.
  • PhoneBooster make multi-threaded if needed (it probably is, esp. for Pi)
  • PhoneBooster make Pi version
  • Add something to get now playing content from file (but: first figure out how, could be via a separate program or something).
  • Streaming output can hang - calls probably need to be moved to a separate thread. ???
  • MicroMPX needs exception handling, just in case.
  • WatchCat replace files instead of placing them elsewhere. For playout systems.
  • WatchCat add CMD /C
  • Thimeo School
  • ABDP remove stuff that's no longer needed? BUSY for low CPU
  • Optimize ABDP
  • Input and output gain for command line version (like for sound card)
  • Dynamic adjustment of priorities
  • Sooth effect
  • Crash ProppFrexx
  • Update Omnia.SST presets
  • AES67: Add WheatNet
  • Create file when input fails
  • Installer: Make installer aware of programs like MediaMonkey, AIMP, .....
  • HD delay
  • Document JSON interface
  • Documentation: "Processing" page contains all kinds of BS412 info - why?
  • Declipper L/R noise
  • Declipper handle resampled audio better (upsample, find oversampling spikes, then detect based on what remains)
  • Console version: Read sample rate and bit size from WAV header
  • # bands selections should allow option to insert a band instead. Or ask what to do when you change it.
  • AES67 thread affinities and priorities
  • Add resampler

Hi all, it took a while before we could post this beta because there were some issues that were caused by integrating the STX interface, but I think (nearly?) everything is ok now. If you notice anything strange, please let us know!

Can you please share the link for the updated declipper? I see you have a gui fix mentioned.

Release hold in MB has also been added. That should be in the green list.

"Limitless" without Dynamic speeds (7bands) - 15.3% CPU Usage [whole HD preset]
"Sane" with Dynamic Speeds ON (7 bands) - 17.7% CPU Usage [whole HD preset]
"Very Low" with Dynamic Speeds ON (7 bands) - 16.9% CPU Usage [whole HD preset]

So still much higher CPU usage with DynSpeeds.

updated for beta011

Interesting is that, for example, dbx 286A do exactly same thing and it's doing it in realtime.
