Hi Koon,
I re install Console : it is not working better.
I tried Reaper :
When Reaper is scanning the plugin i have the error :"Plug-in"VST_SSEFIR.DLL" executed invalid operation during scanning.
If i dont select the option "Get VST names/type when scanning"
Reaped load the plugin but crashes when i tried to use it ....
Reaper load my other plugins fine.
My OS is XP does it makes a difference ?

The difference I can imagine is,
(1) XP, but SSE is available on XP.
(2) "other plugin". please try "without" any other plugin.
This is my 1st VST so I don't know how it will work on other peoples environment.
Where is the VST guru?

Hello KOON once again
there is an idea ho to improve greatly the plug in accuracy
cant say how i can be done but
the main concept i found on the DSPre 1 holm acoustic
so the idea
sure you understand what i mean....

Hi, decimation (X) for frequency span << (44100/X/2), {/2 to avoid down-sampling alias noise}
it sounds like professional 🙂
good: accuracy, steep filter at lower frequency area with small CPU load
difficulty(1): maybe with range control UI / adaptive sampling rate / upsampling + interpolation before output, the source code will be something huge one.
difficulty(2): audio fanatics will not like decimation, they love upsampling and bit-perfect.
maybe simply expand to 8192taps, should be acceptable solution😱

Hi Koon,
I have installed VisualStudio 2010 C++ express and Steinberg VST SDK and try to build the dll .
But audioeffectx.h is not in steinberg SDK , could you explain me ?

another question...
fir_avx - working perfect
fie_avx_Eq- after any change just hang up the reaper....
could you suggest something?

Hi Mike, great 🙂
I will take a look this evening.
please check your VST SDK version, "How to compile the source code you need Steinberg's VST SDK (2.4)"
cka3o4nuk,
One thing I noticed now, This debug routine is alive on VST_AVXFIREQ.
Please make "C:\VST" folder and try again.
//debug
FILE * f;
_wfopen_s(&f, L"C:\\VST\\FreqGain.txt", L"w");
fprintf(f, "i,freq,gin\n");
for (int i = 0 ; i < DEFTAPS/2; i++)
{
fprintf(f, "%d,%7.2lf,%3.5lf\n", i, (float)(SampleFreq * (i + 1)/DEFTAPS), Gain);
}
fclose(f);

Mike, I found
vstsdk2.4\public.sdk\source\vst2.x\audioeffectx.h
and,
/arch (Minimum CPU Architecture)
use SSE2.
add .def file into the project, contains..
EXPORTS
VSTPluginMain
main=VSTPluginMain

Hi Koon
I always trying to build myself the dll with VST_SSEFIR.cpp source but now i have errors in building :
1>VST.obj : error LNK2019: symbole externe non résolu "public: virtual void __thiscall AudioEffect::canProcessReplacing(bool)
Do you know where is the problem ?

Hi Mike
canProcessReplacing found in audioeffect.cpp
and,,,
#if VST_2_4_EXTENSIONS
canProcessReplacing (); // mandatory in VST 2.4!
cEffect.processDoubleReplacing = processClassDoubleReplacing;
#endif
So, please check your project has audioeffect.cpp and,
aeffect.h has
// VST Plug-Ins SDK
// Version 2.4 $Date: 2006/06/20 17:22:55 $
:
#ifndef VST_2_4_EXTENSIONS
#define VST_2_4_EXTENSIONS 1 ///< Version 2.4 extensions (01-01-2006)
#endif
if not, you are loading lower version VST SDK?
(VST, ASIO, too much confusing.. but some kind of standard)

Hi Koon,
audioeffect.cpp and aeffect.h dont have :
#ifndef VST_2_4_EXTENSIONS
#define VST_2_4_EXTENSIONS 1 ///< Version 2.4 extensions (01-01-2006)
#endif
So does i have to add this ?

So does i have to add this ?
What is the version number on the head of aeffect.h?
maybe you have different version.
I'm using "vst_sdk2_4_rev2.zip"
do you have same one?

Hi Koon
When i checked aeffect.h i mistaken , so lines :
#ifndef VST_2_4_EXTENSIONS
#define VST_2_4_EXTENSIONS 1 ///< Version 2.4 extensions (01-01-2006)
#endif
are present in the file and version is :
// VST Plug-Ins SDK
// Version 2.4 $Date: 2006/06/20 17:22:55 $
The SDK fike is "vst_sdk2_4_rev2.zip"

So you have 2.4 SDK, but your project can not find 2.4 SDK?
I think you also have 2.3 SDK and your project is looking it.
Maybe,
(1) remove 2.3 SDK. search audioeffect.h for whole PC, if found more than 1, duplicated.
(2) Check Visual Studio, Project, Property, VC directory.
I have "C:\VST\vst_sdk2_4_rev2\vstsdk2.4\pluginterfaces\vst2.x;$(IncludePath)"
And, Can you build sample VST, like adelay or again? This is important.
It shows how to build VST.
Then, you can use my source code to build yours.

Hi KOON3876,
Thank you for sharing this groundbreaking work. It's very exciting to see FIR filters on Windows for free. However I don't feel that the VST platform is the best route for implementation. I'd much rather see a crossover done in the audio driver so all audio played on the computer will be processed before reaching the soundcard outputs. I looked into writing virtual audio drivers but the learning curve is very steep.
There's also another alternative that involves 2 sound cards and a standalone application doing the processing. Card1 will be designated as the default sound on the system. The physical output on Card1 will be looped back to the input on Card1 with a patch cable (preferably on the digital path to avoid unnecessary conversion to analog). Then a standalone program running on the PC will read the input from Card1, do the FIR processing and output the filtered signals on Card2's outputs. This way unprocessed data never reaches Card2's outputs.
