Audio VST plugin needed, simple but non existent in the market

[LordAdef]

Hi guys,
Believe it or not, I need the simplest of the simplest Audio VST plugin. But... I searched everything but there isn't any!!!!!
I know Marinus have looked at the VST documentation already, but who knows if anyone here wanted to have a go.
I work with DAWs (digital audio workstation) everyday of my life. When mixing a music track, all separate audio tracks (at al) goes to the DAW's stereo Master track.
What I miss is a simple plugin to draw the resulting waveform representation. Simple right?

But the existing ones are oscilloscopes kind of  plugins with many functions, but the waveform representation is either absent or restricted by the window.



Anyone interesting in making one???


There are thousands of threads in specialized forums of people looking for something like I am proposing, just saying..



Regards Alex
ps: Hutch, I didn't know where to write this thread, Workshop seemed right.

Hi LordAdef

I never built a vst plugin before, but did you took a look at IsotopeRX ? It is a standalone app, but suitable for usage with plugins and the best available in the market concerning audio restoration.

For open source you could give a try at

Oi Guga, tudo bem?
So, I sure know Isotope RX. It's an extremely powerful tool, I used a lot and it's used all the time where I work. It's our prime tool to clean audio recorded at live locations. But it's quite too expensive and really off of what I need.
Have you heard of the JUCE framework/SDK? I found a tutorial that do just that, drawing a wave representation. I might have a look a that, although I will have to touch.... arghhhh.... C++..... But let's see...

Only had a look at the VST SDK and just like their (Steinberg) ASIO SDK it's all a mix of COM, STDCALL and C calling conventions.  ::)
I have finished the ASIO translation but don't feel the need to do the VST translation very soon.
Busy with other things....

i used a few times nuendo (or something similar) which i think is (or was) from steinberg. and i think nuendo used those vst plugins...but i have never tried to program one...

[LordAdef]

thanks guys!
I myself would try to code it myself. I've heard the VST sdk is not for the faint of hearts....
But I will try this JUCE framework, that saves all the hassle and looks like has some nice audio prebuilt  stuff, including a real time buffer drawing routine.

Alex, I just found this on kvraudio,

here is the asm source code,

Oi Alexandre. Te mandei inbox por aqui e te encaminhei meu face por inbox.

Eu uso o Isotope quase todo santo dia. É incrível para restauração de áudio, sobretudo quando se trata de áudio oriundo de películas telecinadas em 16mm por exemplo.

Hi Siekmanski, judging by the code of VST, it is quite similar to what is found on VirtualDub plugins (basically are simple pointers to structures). Indeed, easier then i expected, though :t :t :t
