Digital Filter Design and Implementation within the Steinberg Virtual Studio Technology (VST) Architecture
Steinberg Media Technologies, GmbH, of Germany, is one of the leading manufacturers of pro-audio hardware and software products. Within their software realm, they have developed a plug-in architecture for adding third-party DSP functionality for program developers who choose to support it. The architecture, commonly referred to as VST (Virtual Studio Technology), has become a standard for third-party add-ons over the last decade, partly because of its cross-platform functionality. The software development kit (SDK) for VST plug-ins is available free of charge from Steinberg, and is optimized for building within Microsoft’s Visual C++ environment on x86 PC’s, and on the CodeWarrior environment for Apple computers. This project focuses on the implementation of classic and experimental filters within the aforementioned architecture, created and compiled on Visual C++; rebuilding these examples on a Mac should be a straightforward process. DSP literature is included, although only to a certain depth so as to not overwhelm the reader with the mathematics behind the process; a recommended reading list is included for that purpose. The paper is designed for introducing general signal processing theory as well as documenting the process of creating VST plug-ins in a clear and understandable method. A suite of VST plug-ins is produced and the entire source code is available online as appendix to this project at http://www.thedigitalvortex.com/appendix.html
