Stereo Tool 9.03 BETA006 Pfew, this was a really really difficult one. I've been working on an update of the Stokkemask filter. For most people here, this won't be very useful (but: see below). In some places though (the Netherlands and Belgium) this is a mandatory thing that stations have to comply to. For most processors, the only solution is to either broadcast in mono or reduce modulation to about 68 kHz. Stereo Tool, Breakaway, and the Omnia 7/9/9sg are - to my knowledge - the only processors that can enforce Stokkemask compliance. So what's new? Well, the existing filter was kinda sloppy, but worse, had more effect on the audio than what was necessary. Mainly on stereo separation, but it could also make the sound a bit "grainy". The grainy effect is gone now, and the effect on stereo separation is reduced by about 40% in extreme cases (so it should be more in non-extreme cases). And the filter is much stricter than before. Why would this be interesting for people outside of the Netherlands and Belgium? Well... the whole idea of this mask is that it improves reception. And now, you can turn it on with much less effect on the audio than before (the effect was mainly noticeable when the audio was very loud and stereo was wide). WARNINGS: IF YOU HAVE TO BE STOKKEMASK COMPLIANT, PLEASE DO NOT USE THIS VERSION ON-AIR BEFORE READING THE FOLLOWING: 1. The new filter uses FAR MORE cpu than before. Because of that, by default, existing presets will start up in "LEGACY" mode. Which is however kinda broken right now (I will fix it tomorrow to make it equal to the old version). So, right now, if you've carefully calibrated and measured your signal, please avoid this version for now. 2. The new filter works best if you boost the clipper precision to the maximum value (18). 3. We still have to add a final filter that detects and removes any remaining filter overshoots. 4. ALWAYS be aware of this: Different measurement devices will show slightly different Stokkemask graphs. Either measure with the same device that your regulatory agency uses, or stay slightly below 75 kHz modulation. For now, to test the new mode, go to Stokkemask and disable Legacy mode, then set the clipper strictness to (or close to) 18.

1000 NaN errors on the ProcessingChain, glitches in the audio. Beta 006 32bit can be considered as failed build, tested on Windows 10 x32 version, Windows 7 x32 version, and Windows 8.1 x32 version. I'm in bed now, so can't take screenshots at the moment 9.02 BETA018 was all fine and stable. |

Confirmed. It's caused by Stokkemask "legacy mode" - as soon as I turn that off it's ok again. In debug mode it's ok as well - it only fails in the release build . Will look into it today. |

It uses enormous amount of CPU with strictness 18. Actually even with strictness 8. Also more cpu usage when graph is OFF. |

Is it posible to use GPU for processing instead of CPU |

I know. It sounds better though and is stricter. And I still need to try to make it work as well with lower strictness settings. So, if you have the CPU power available you can run it. (I can ALMOST run it at 150% at the normal 1 thread + multicore mode on my pc).Actually even with strictness 8. Also more cpu usage when graph is OFF. I'm going to revert legacy mode to what it was before, that should fix both the NAN's issue and the performance. And make sure that anyone who has it setup correctly doesn't have to worry about it. |

On my PC i can run it. But it's i7 4790K at 4.7GHz and still with 50%. Old E8500 at 3.6GHz ccant work with this at all. And with legacy stoke makes 85% cpu usage already. |

Plan:Step 1: Offer both legacy and new mode (legacy with same behavior and CPU load as before). Step 2: Optimize new mode to work with lower CPU load, maybe slightly less strict. In the end I hope that even if your CPU can't handle the extra CPU load required for the more precise filtering, the new method will still give a better sound than the old. But for now, if your CPU can't handle it, stick with the old version... |

Hi, I have try your last version but I receive: Exception Occured in ProcessingChain Thread (Exception 0xc0000005 at address 0x7ff65202c3ad, read/write=0, r/w location=0x263c26eadc0). Offset-info: 0x7ff6528ab409 Restart will be attempted. and i restart and loop on this error. Only composite clipper and FM transmitter is enabled in processiong (ST on transmitter side) |

Hi,
I also recieve a lot of theese warnings (even when I do not use Legacy mode in Stockmark) but it works anyway they are just anoyingI have try your last version but I receive: Exception Occured in ProcessingChain Thread (Exception 0xc0000005 at address 0x7ff65202c3ad, read/write=0, r/w location=0x263c26eadc0).
