CHANGES:
  • Improved Stokkemask - output is stricter (closer to the mask), so it has less impact on stereo separation. (*)
  • Memory usage reduced by about 12 MB

    (*) We need a measurement to make sure it's as tight as before. It probably is - but some testing is needed to make sure. I can measure it with my own analyser and with MpxTool, but neither gives a perfectly accurate result. Most importanty, I would like to know if setting the new "New looseness (experimental)" slider to 100% (0% is equal to previous versions) has any effect on compliance. Below 100% there's not really any difference in what I'm measuring, at 100% there is a small difference.

    OLD CHANGES:

    PLANNED:
  • Stokkemask: Improve further
  • Stokkemask: We don't care about CPU load, try adding more stages
  • Stokkemask: Measure
  • Show warning when using MME with wrong sample rate
  • MicroMPX: highs idea BUSY -> Find beta testers
  • Try I/Q Clipper mode BUSY, first part works, highs are coming out slightly too loud, due to LPF? Might be good enough...
  • Test preset that causes buffer to run empty - why? --> Settings issue, maybe add a popup for this situation (buffer is slowly filling up or running empty)...
  • Bug report: Linux version uses 100% CPU on one thread, even in bypass mode (must be sound card thread?) -> Not here. Not sure what's going on.....
  • Test 64 bit sound card exception handling in ProppFrexx - that wasn't the problem... apparently
    -
  • Declipper: Put startup in system tray back in Declipper (at least in the Winamp plugin version).
  • RDS: EON: Support for other type of AF frequencies?
  • RDS: Support for AF method B
  • RDS: RT end at \n
  • Brian, NAB
  • MOBO
  • uMPX encoder/plugin: Sound card speed message
  • uMPX decoder: Add multicast subscribe
  • Add MagicRDS AF method B support

Ah, oops. I copied it from the 9.02 thread and that build had failed in the last beta there. Fixed now.

CHANGES:
  • Stokkemask: Improved further (looks about equally strict, but I can squeeze over 1 dB more anti-phase content through than with 9.02). NOTE: SETTINGS ARE DEFAULTING TO 9.02 BEHAVIOR BECAUSE I DON'T KNOW YET IF THE SIGNAL IS EQUALLY STRICT, AND I DON'T WANT SOMEONE TO GET FINED FOR HAVING STOKKEMASK OVERSHOOTS. To get the new behavior, set "New looseness 1" higher (50% should definitely be safe, I'm not sure about 100%), "New looseness 2" to 30%, and "Side level" to 40.

Something odd using the latest beta SA:

Enable 'Restart on crashes' under Configuration to automatically restart if this happens again.
EXCEPTION OCCURRED IN ProcessingChain Thread (Exception 0xc0000005 at address 0xf9ec02, read/write=1, r/w location=0x197394). Offset-info: 0xddeda4

EDIT: Tried in Beta 001:

Enable 'Restart on crashes' under Configuration to automatically restart if this happens again.
EXCEPTION OCCURRED IN ProcessingChain Thread (Exception 0xc0000005 at address 0xd04762, read/write=1, r/w location=0x197394). Offset-info: 0xb4e314

Post subject:  Re: Stereo Tool 9.03 BETA

Yup, was just reported by someone else as well. Caused by the memory optimizations that I did - should be fixed now, so the next beta shouldn't complain anymore.

Build 003 wasn't correctly uploaded. Which explains why it still crashed.

CHANGES:
  • Removed (moved to Extreme Tweaker for possible future testing) some Stokkemask settings that had a bad effect on compliance. Good settings are 50% / 30% / 40 dB (without the 40 dB it should be fne too, but there's a bigger chance at overshoots at the bottom of the mask. 100% for the first value increases overshoots!!!!! 39 and 38 should be safe as well - but I haven't had time to measure those separately anymore. Anyway in the older versions this value was set to 0....... Setting it higher may cause an audio quality reduction.

    OLD CHANGES:
  • Crash fixed
  • Stokkemask: Try I/Q Clipper mode, highs are coming out slightly too loud, due to LPF? Might be good enough... -> Idea doesn't work
  • Stokkemask: We don't care about CPU load, try adding more stages -> No effect
  • Stokkemask: Default back to 50% for safety - that way we don't have to worry about breaking older versions. And we still get 90% of the improvement that way.

NOTE: SETTINGS ARE DEFAULTING TO 9.02 BEHAVIOR BECAUSE I DON'T KNOW YET IF THE SIGNAL IS EQUALLY STRICT, AND I DON'T WANT SOMEONE TO GET FINED FOR HAVING STOKKEMASK OVERSHOOTS.

Below 100% there's not really any difference in what I'm measuring, at 100% there is a small difference. ---> RESULT: 100% is bad, keep at 50. Then it's ok.
