Why are you using the scalar instructions instead of the packed / parallel instructions?

I use the parallel instructions in most of the performance sensitive code, but not everything is suitable to be parallellized.

In this specific case, the compressor, each sample depends on the samples before it. So I cannot process the next sample until I've processed the current - that's why I cannot process samples in parallel (cannot is a big word, it might be possible to find some tricks or to parallellize parts of the code. I just haven't seen them yet.)

Question about the coupling parameter in the multiband.

When i slide it to 100% much songs sounds like " muffie"
Try this song whith the r type preset from Bojcha
Alexis Jordan - Happiness
sounds not nice when you slide it to 100%
Or is this normal?

Setting BBP (default Rustonium settings) MPX output level to -3.0db feeding MPXTool, the peaks in MPXTool (default -3db input) frequently hit 100% modulation on most songs.
Setting ST (R-Style, latest beta) MPX output to -3.0db, with no composite limiting, peaks only frequently hit 92/93% modulation in MPXTool. Composite limiting has to be turned on quite high (~108/110%) to achieve peaks hitting 100%.
Is that expected and correct behavior?
And is sound card input still only 16 bit resolution ?

I was just wondering if and how that relates to your question over on the Intel forum about portions of the code that won't vectorize. fft_abs_sse2[2cc] = max(fft_abs_sse2[2cc], strength * m); for (int c=0; c<f1; c++) { temp[2c] = one_DIV_bass_static_clip_level_dynamic; temp[2c+1] = one_DIV_bass_static_clip_level_dynamic; }

Forget about the instructions now. We have a problem with the lowest band in MB ... The "blop" effect . Also i see in the output scope some wave strange behavior when i put on low freq. tone say 35 40 Hz ? I can hear the "blop"effect . The only strange thing is that when i put he Coupling to 100% this effect is reduced a little . I will make a video to show you all what i mean . And i`ll put it in the post after i make it. Think that there is some wrong "calculation" in the filter.... other bands are not giving this effect. Tested with Bandpass OFF , same thing .All is coming from the MB

I compared with Beta 45. I did nt try the next ones cause of cpu overload.

With coupling set to 100% all the bands will do exactly the same, so it behaves as a singleband compressor, although 'band mix' still works. So don't set it this high! I think I should probably display the 'band calculation matrix' that is used. When I made this slider I viewed it by writing it to a file and it really helps to see what's happening. It might also be useful - extreme tweaking mode - to make this editable manually.

Preset is already VERY well balanced (maximum what bands can give) but yet preset/mb do full processing. For a reason coupling is disabled in preset - it does not need that, also, crossovers are tuned maximally to separate bands well already.

So , the video with the strange behave . When i turn the MB off it stops . Hans ? http://www18.zippyshare.com/v/98468466/file.html

And is sound card input still only 16 bit resolution ? - Is it post amp at 0.00 (100%) ? - Turn RDS OFF, since in BBP was not there when you tested - Set composite to 102% - Pilot 9.00% and RDS 4.53% Result: http://i.imgur.com/6l04IFa.png If you want RDS now set composite to 102+4.5, so ~ 106 or 107%.

In BBP composite clipping can not be turned off, so the comparison is not fair in my opinion. So, in order to make a good comparison, you should at least turn the composite limiter in ST "ON" since ST does not have a composite clipper YET. (i assume BBP uses this to some degree, depending on preset)
