ddx_sdk4

OverviewThe DDX SDK V4 lets you write DirectX filters using Delphi, without having to mess around with DirectShow and COM. This documentation assumes the following:· You are fluent in Delphi.· You know about audio processing algorithms. (If you‘ve written a VST plugin in Delphi, you‘re in a good position.)· You don‘t want to mess around with COM or C++. There are some limitations on the types of plugins that you can write using this SDK, because to make things simple I had to make some compromises. With the DDX SDK V4, you can write filters that can:· Perform in-place filtering· Process IEEE 32-bit floating point and/or 16-bit integer PCM data.· Process mono and/or stereo data. · Have up to 16 parameters.However, this SDK does not support:· Mono->Stereo processing (although if you only accept stereo input, many platforms will automatically convert a mono track to stereo before feeding it to your plugin.)· Asynchronous (ie overlapping-blocks) filteringIf you are seriously interested in multi-pass or asynchronous plugins, you really should consider learning C++, since you will have to work at the advanced end of town. Here is how the final plugin will hang together:
