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, I will take a look tonight.

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 ?

KOON3876 · 3rd December 2011, 09:31 PM

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?

mike34300 · 4th December 2011, 01:39 PM

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"

KOON3876 · 4th December 2011, 04:32 PM

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\v st2.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.

Can you time-allign drivers using Reaper?

Thanks

Time-allign, means "delay"? yes, I can use delay VST.

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.
