If you've wanted to develop DirectX plug-ins using Borland Delphi, you're going to love this!
After writing the Clone Ensemble and Bass Chorus VST plugins in Delphi, I wanted to port them to DirectX. I could not find any Delphi DirectX SDKs on the web, so I decided to develop my own.
If you are fluent in C++, you should check out the Cakewalk DirectX Wizard. If you want to dig in further, the Sony Audio Plugin Development Kit (formerly known as Sonic Foundry PIDK) has lots of valuable doco and sample code. Finally, the DirectX SDK that Microsoft ships with MSDN is the ultimate resource, where you can see the C++ source code for the DirectShow filter classes.
However, if you would prefer to use Delphi and avoid messing around with COM and the DirectShow interfaces, the DDX SDK V4 is for you.
Download the Delphi DirectX SDK V4 (490k)
