CLAS - Compressive Loudness Audio Shaping

skOre · 28 Dec 2005

did some testing, and it seems to boost loudness too much... will investigate...

infuzion · 28 Dec 2005

Interesting! A few things; looks like the orig schematic has both a High & LowPass filters, while I don't see one in your SM version? Also, in Filter/Compressor > Shape > Interpolate, there is a graph connection missing... but then again, I don't even know what is does 🙂

skOre · 28 Dec 2005

Well yes, I completely missed that out. Was at a different screen and couldn't read whether it was a hpf or lpf 😉

btw, I contacted David McClain of Redefined Audiometrics about to what extend one could use the algo:

"...Now I know that it is actually just an eq with a compressor, but I wanted to be sure that I don't break any copyright of yours, so if you do have a patent/ copyright and don't want this to happen - just tell me and I will crop it again. The same goes for legal issues if I or another user of the forum wants to use this in a piece of software. Please do inform me if I'm doing something wrong."

"Hello David,

No, feel free to duplicate our results. The magic is as much in the dynamics as it is in the compression curve and EQ..."

Will clean up the schematic and repost it (probably tomorrow).

wth, redownloadand check if it works correct this time. I had no chance to check it at all...

skOre · 29 Dec 2005

Ok, last uploaded version seems to do the right thing. Just that I'm out of my headphones atm, and thus out of any trustworthy monitoring... Maybe somebody could check over it to measure its effect?

Thanks for the example and website link skOre

Thanks for the compressor. skOre wrote: Ok, last uploaded version seems to do the right thing. Just that I'm out of my headphones atm, and thus out of any trustworthy monitoring... Maybe somebody could check over it to measure its effect?

I used the synth that came w/Dasdeck's phaser (removing the phaser), & attached the mono output of it to SM's meter, then another to your compressor in stereo, then stereo out. I found no real difference in sound, though perhaps slightly "filled out". The metering seems to indicate that the original will often peak higher (esp for long sounds), but the compressed audio will peak longer. I changed the shape settings with no disernable effect. It also seems to eat up about 5-10% CPU on my machine, though I'm not too certain about that (I have Firefox open also); I had to delete it to get the CPU down lower.

I just had another look through your example again and i noticed two things, it would seem as if the code for SVF3 is broken. You have also left a stream add which is not connected to anything in the Filter/Compressor module.

{edit} link moved: http://refinedaudiometrics.com/products-clas.shtml They just made a VST of it... pretty quick, I wonder if they used SM for it? 😉

{edit edit}BTW, I have another idea for a psudo compressor/exciter, if you're interested in it.

skOre · 31 Dec 2005

No, they had it on there before. And yes, I'd be interested in ideas 🙂

Hey Skore, FYI the clas works in FL and Cubase but it crashes Wavelab. In FL I get very nice results on the master, got a set of KRK ST8 Monitors here, bass and beats blend very nicely when tweaking the shape a bit..got a good punch on the kicks! 😀 😀 😀

AngularMomentum · 13 Jan 2006

I tested some other stuff exported from synthmaker, like the satndard compressor and it all seems to crash in wavelab, so probable it is SM in general and not the clas that is crashing wavelab.

infuzion · 13 Jan 2006

What version of WL? I use 4.

AngularMomentum · 13 Jan 2006

Wavelab 5

skOre · 14 Jan 2006

I'm still not sure whether I did this thing right. I think that I should release a version that is easier to tweak. I also came to know that the sambeans waveshaper keeps resetting. Thus the initial algo is distorted a tad.

AngularMomentum · 14 Jan 2006

Yeah, I noticed it isn't reacting to presets either...still it is a nice tool to play around with...if the strength of the high and low could be adjusted would be great! Also I noticed that putting this in some SE projects I have good results...really polishes some of the patches nicely...I wonder though what it will sound like if You got that algo sorted. 🙂

Hi skOre,

i know it's an old thread but...

Please make this baby work with newest SM-Version!

I got this out of your great Modul-Pack but all my SM's crash if i try to add it into new project...

Or is this already been ported?

Thanks, SUNSynth
