so when are you releasing it gtek ??

gtek · Post by **gtek** » Thu Apr 28, 2005 8:05 am

Hehe,

The release is not X86, but is meant for a dedicated dsp board. The source is already on this forum somewhere.
If someone could give me a quick course windows programming i could be of some help in the future

@johnysun

I'll try to process your samples tonight.
Gotta rush to the deskjob now.

Hi gtek,

nice to hear from you.

Do you mean you will code a plug for protools?

citizenchunk · Post by **citizenchunk** » Thu Apr 28, 2005 12:46 pm

i have whipped something up (for VST win), but i don't really know what to call this effect. is "Orban" a sufficiently cool name? or am i just asking for a lawsuit?

regarding the patent: it seems to be a patent on the hardware implementation only. so i think that any digital implementation of a similar scheme would be ok.

ps - i'll post it later on today.

No, this code is running on an embedded DSP board. This means that it is a standalone device for audioprocessing. ( like a rack mount device ).
The source is written in C++, so porting it to visual C++ will not be sooo dificult.
I think pc based processing is a next challenge for me.

@Citizen chunk
Well this psycho acoustic behaviour of the brain is not patented

Simple because it can't be patented.
The schematics ofcourse are patented, the usage of the name orban and 222(a) is also prohibited.
This stereo enhancement effect is described in a 170 pages thick pdf published by some science dude.

For this description of this psychoacoustic PDF you might contact MaxCrest, which is also present in this forum. He's the "threadstarter" of this thread.

by this you must mean, "porting it to the VST API," as Visual C++ is merely the IDE that most of us use.

if you've already got it in C++, it should be trivial. (that's the "kiss of death" right there.

) if you need help, let me know, or bring it to the Developer forum, which is full of programmers much more knowledgeable than i.

Well actually, i left C(++) programming on the pc behind when windows came around.
Since then i am merely focussing on embedded and dsp-embedded programming in assembly and C.
I have no clue how a vst environment would look like, but as i said before, everything new is a challenge.

just a quick heads-up: i've posted an alpha for my stereo-widening thingy, which implements my interpretation of the topic of this thread. please try it and let us know what you think.

check out the thread on the Effects forum for details.

Wicked, downloaded it, no time to check tonight though but will give it a try tomorrow.

Don't forget that the original 222 is also equipped with a "Width Limit" feature.
It measures the ratio between the L+r and L-R signal to prevent over-exagerating of already wide signals.

Hi Maxcrest,

you are working on a 222a clone, too?

At the beginning you only asked for a transient-detection-method, so nobody knew it's for your work on the clone

i suppose this could be arranged. my question for Orban would be: "what is a adequate mid/side ratio?" is there any radio-world standard to go by?

also, (in radio) is this meant to be an automatic process? or is it adjusted manually by the engineer? are their any radio engineers out there?

Maybe opening an extra thread dedicated to the radio engineers ...
