CHANGES:
- Finished optimizing performance Auto EQ etc. DONE, 9.5 times faster than in version 8.52!
- Finished optimizing performance of AGC
- Optimized performance of Multiband 1, Multiband 2 and Singleband in RMS mode (factor 3).
- Buffer issue Triple
- SCA was broken - only for threads > 1
- Gray screen Wolf

OLD CHANGES:
- Optimized Auto EQ and new AGC performance (partially done) -> Output can be slightly different with 'Low CPU' enabled (possibly even better!)
- Added MagicRDS remoting support (Pira program)
- Auto EQ was missing in main page
- Increase NAN detection thresholds (test with new AGC with insane input levels)
- Omnia.9 return clipped audio via callback
- Omnia.9 logging remove time and \n
- Scheduler killed new AGC setting!
- MicroMPX decoder web interface could hang on right click on tray icon
- Buffer issue Generic plugin - needs to be tested.
- SST increased contrast
- SST wrong word in MicroMPX settings

TODO:
- Combined and reorganized Compressor calls for better cache behavior and fewer separate threading calls.
- Omnia.9: Clean up L-R area when AutoPilot is active -> L-R should not even be demodulated in that mode.
- Optimize Peak mode as well? -> No, but Average is possible (and done now).
CPU load with identical settings: 6.7% before combining threads, 6.5% after, ??? after improving cache.
- Add goniometer More places?
- SHEETS
- RMS compressor mode fails in 8.53??? Just dies, no more compression, but audio output and limiters still there.
- SST installer
- Check compressor levels further
- Would a times 32 version be useful? (Or at least for ARM-based?)
- Omnia.9: Give more output values for smoother meters
- WatchCat website
- Set maximum to L-R asymmetry?

- One bass page
- New bass effect
- Revisit new Hard Limit / Final Limiter with Matt
- Report of Linux Jack version crashing - since 8.52

- GUI: Hide disabled stuff, far less confusing / much cleaner interface.
- Talk to chip
- 2 jaar
- Fardau
- Remote control via web interface doesn't work anymore for some people due to SID.
- -24 dB side chain range?
- Dummy data sturen om initialisatie te doen voor geluidskaart openen.
- 2nd AGC with higher threshold for voice tracks
- Bigger font on 4K screens

Ow. That's odd. There should be no effect at all on the output levels (the Auto EQ and new AGC, and now also new compressor modes can give slightly different output levels, but that should be all). Are you still seeing it with 004? If so, can you send me your settings so I can test with the same settings? Thanks.

Hans,
It's much less frequent with beta 004, but is now showing up the same with Low CPU on or off.
It seems to hang red for longer now on beta 004, it's still brief but not as short & sharp as it was on beta 001

I'll admit I didn't have much headroom, & it was only showing up on a few songs of Mariah Carey's & Martika's Toy Soldiers.
It's never both output channels together going red either, it's channel specific, Left or Right, one at a time, obviously depending on the processing.
I've pulled some of the levels down now, & got more headroom for these loud songs.

I guess it's just the way the audio is in the music & the way they're processed, because these songs have lower input levels than some others, but the red output levels are only showing up on these, not the ones with higher input levels.

O, you aren't using the limiter or clipper?

Yes, I'm using the limiter & both advanced & composite FM clipper.
Funny I can't get it to come up red this afternoon with FM transmitter turned on, but it'll do it with FM Transmitter turned off.
I've reduced the MB1 output level by 1.75dB & that's fixed it.

Ok, if it's very occasionally there's nothing to worry about. The clipper and limiter can very very small overshoots, because of that I'm reducing the output level after the clipper by something like 0.01% or so. The harder you drive the clipper, the bigger the chance that at some point in time, 0.01% isn't enough anymore... However, a < 0.01% overshoot doesn't matter anyway.

Installed 8.54 from 8.50. Error screen and no audio from M-audio delta 192 card. Couldn't find a combination that worked. Re-installed 8.50 & everything came back fine.

Updates usually install with no issue. Don't see why this one isn't working.

Hans would probably be able to debug it better if you posted what the actual error you encountered was...

Yes, I need the exact version (001 or 004, 32 or 64 bit, stand alone, VST or DSP plugin) and exact error text. Otherwise all I can tell you is that it works fine here.
