I did see something strange in the slopes of the MPX signal when using the multicore version - at single core it's probably fine. Will check.

CPU load improvement: Clipper load is shared over 2 cores now.
Works great! 3-4 steps more CPU-Strictness possible than before on my (older) dual core system.

Things look better here too! :)
Composite clipper and SSB seem to add a fairly significant load though. (A quick look shows around double the CPU usage on my i3 - does this seem right to you?)
Was running a quick test with strictness at 20 and stronger clipping at 30. :mrgreen:

edit: Hmm, had some audio breakup but think another process may have increased the CPU usage on the machine at that point. (MsMpEng?!)
Will wait and see what other tricks you have up your sleeve but think the earlier settings might be pushing the limits way too much...

Also noted that the advanced clipper metering still stops working when the composite clipper is enabled? Is this intentional?

Can you comment on the effects of 'taking shortcuts' in 'Advanced clipper - CPU' with regards to composite / SSB?

I can increase the declipper Quality slider to 4 and Step size reduction to 96%!
Running a build now. The potential L-R ticking effect is not yet fixed. Will look into that later.
On my XP32 i can now have strctness to 20, SSB, Multipath clipper ON, Declipper to 4.00 / 98% / 25% :)

@dj_szpajda - Try with RDS ON.

I'm testing on a new I5 on Win8/64, it is *just* running three instances (~93% reported total CPU) with CPU strictness at 20, Declipper, MPX Clipper, SSB, Multipath clipper. All 3 running fine for the last one hour. Impressive!

This is how it looks on my 6 core 12 threads.

It doesn't matter, same results, tested on 3 different PC.

With your settings of Strictness set to 20, Stronger Clipping 30%, SSB, Multipath Clipper, Declipper to 4.00, 98% and 25%. I get a CPU usage of 48%. 0=20%, 1=7%, 2=15% and 3=6%.

There's been some discussion of what the SSB looks like in terms of how much if any is left above 38khz. FWIW, this is what the Omnia 9's SSB looks like:

And for what is this Single side band for ?
For Radio Amateurs ? is that SSB you guys mean ? LSB and USB ? used for 3.5 , 7 and 14 Mhz bands ?
