also is it possible to use GPU for procesing instead of CPU
In theory, yes; in practice, not really. GPU's are great for doing thousands of exactly the same calculations at the same time (i.e. calculating the value of a pixel), while for audio in most cases samples have to be processed more or less one-by-one.

Stereo Tool 9.03 BETA009 Stokkemask issues should be fixed, Legacy mode (you can enable that in the Stokkemask page) is now virtually identical to the old (9.02) Stokkemask. In Legacy mode, Stokkemask CPU load is still 6% higher than in version 9.02, I don't know yet why (there are some remaining optimizations that I need to perform, but they don't have this much impact). If you want to use the new mode (non-legacy), it works best if you increase the CPU strictness slider for the composite clipper to the maximum (18). From the previous beta: 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.

Good news: I just found out why the new code was heavier (I wasn't fully running it in legacy mode). Now, it's actually slightly lighter than before. Woo-hoo! (And I still have 1 small optimization remaining). |

Still NaN's in new stoke Also it seems it does not need composite strictness more then 8. Just "Strict post filter" ? |
