Hi, this is a simple but effective plugin i made:
it is simply increase the stereo image of the signal so don't use on mono sources!
I tried and i liked the way it worked so i thought somebody would like to try it, so
i u can download it here:

... Hey, some feedback would be appreciated!

Yes, the effect is really noticiable. Nice work.

Only one thing: You don't need to use the initial MACINTS tmp,0,in,4. Doing this, you break the 12dB 'save range' that DSP gives to all the effects. Just put MACINTS tmp,0,in,1 at the begining and MACS out,0,tmp,1 at the end.

for whatever reason - that link doesnt work with firefox (latest version) - the zip is broken if I right click and save link location as. something with the server i suspect.. ?? I had to use IE to d/l it.

just fyi...

Nice little plugin. Following eyagos recommandation and modifying the code slightly, I would use the following code :

Code:

; New microcode
name "ColHQ WIDENER";
copyright "Copyright (c) 2004.";
created "09/15/2005";
engine "kX";
; comment "";
guid "c72fd388-235e-4719-975b-3fe33e646856";
; -- generated GUID
input inl, inr
output outl, outr
temp tmpl1, tmpr1, tmpl2, tmpr2
control WIDE=0
macs tmpl1, inl, 0, 0 ;tmpl1 = inl
macs tmpr1, inr, 0, 0 ;tmpr1 = inr
macints tmpl2, tmpl1, tmpr1, -1 ;tmpl2 = tmpl1 - tmpr1
macints tmpr2, tmpr1, tmpl1, -1 ;tmpr2 = tmpr1 - tmpl1
macs	outl, tmpl1, tmpl2, WIDE ;outl = tmpl1 + tmpl2 * WIDE
macs	outr, tmpr1, tmpr2, WIDE ;outr = tmpr1 + tmpr2 * WIDE
end

It saves two instructions because the four last lines can now be combined to two. I changed the macsn to macints. That's not really necessary but I prefer it that way. There is some very small rounding in the multiplication sometimes with macs. Using macints with -1, it's certain that the signal is being inverted without any attenuation. Of course that's very far from being audible so it does not really matter.

Don't forget that you can use output registers more than once, and thus can use them as temporary registers (i.e. you can eliminate tmpl2 and tmpr2 above as well).

i.e.

macs tmpl1, inl, 0, 0;
macs tmpr1, inr, 0, 0;
macints outl, tmpl1, tmpr1, -1;
macints outr, tmpr1, tmpl1, -1;
macs outl, tmpl1, outl, WIDE;
macs outr, tmpr1, outr, WIDE;

another opt.:

Code:

macs tl, inl, 0, 0
macs tr, inr, 0, 0
macs outr, tl, tr, -1
macs outl, tl, outr, WIDE
macsn outr, tr, outr, WIDE

Max M. · Sep 16, 2005, 10:55 PM

or even more:

Code:

macs outl, inl, 0, 0
macs outr, inr, 0, 0
macs t, outl, outr, -1
macs outl, outl, t, WIDE
macsn outr, outr, t, WIDE

8-)
