I would recommend reading this pdf first..

@Citizen

Your plugin does not sound bad at all if set up properly..
My settings are:

Delay : 0.02
Modulation : 35%
Attack : 2.5
Release: 3.2
average: 100ms

thanks for the link. after checking this out, i've pulled another 180º with this project. but it's for the better. expect something posted in the next day or 2.

Keep up the good work!
I like your plugin very much, i never heard thats kind of stereo expansion but this is awesome, i think the best i ever heard in the plugins world! I hope it will get better! Otherwise a question: How much is the internal precision of this plugin? And what is the highest samplerate it can handle?

( i'll put in C )
monosave=L+R;
mono=Compress(monoEnvellope,mono,thresshold,ratio);
stereo=stereo/(mono/monosave); // =stereo* 1/(mono/monosave); mono/monosave = control signal of compressor.

So loud parts are enhanced quite parts (below the threshold) aren't?
Interesting algorithm, but wasn't the original question about transient widening?

OK, I did a small plugin according to the manual posted here. So it works different to what gtek wrote.

Can you perhaps discibe the internal structure?..
Does the release slider has something to do with the transient detector?

The main algorithm looks like this:

Code: Select all

// C++

Signal mono = (left + right) / 2;
Signal side = (left - right) / 2;
         
Signal transient = transientDetector.update (mono);

side += side * transient * amount;         
         
outL = mono + side;
outR = mono - side;

Additionally there is an envelope generator before and after this process which are used to prevent audioable vomlume changes.

Does the release slider has something to do with the transient detector?

A release slider?

just out of curiosity, did you typedef the "Signal" type? i assume it's just a typedef for float.

Right, this way you can easily change it from 32 to 64Bit processing (good for advertisements).

This sounds very good!...But unfortunately it sounds distorted when wrapped in dx...

MaxCrest · Post by **MaxCrest** » Fri Nov 04, 2005 6:15 pm

Bump......Still using Spartacus,and still very happy with it.....Can we Expect a v2???

gtek · Post by **gtek** » Mon Jan 16, 2006 2:29 am

I'm very keen about version 1.0 of spartacus. But i'm missing the width limiter, since somtimes the stereofield gets soo exaggerated that it almost clips...

I'm planning to join the world of Dx/vst programming soon.
If anyone could tell me what and how i would be pleased. Templates?

Regards,

This plugin is running 24/7 on the soundprocessing chain on our shoutcast stream, still happy!...It would be superb if we could expect a second release...

Transient detector...
