Digital Filtering in Faust and PD

This appendix describes use of the Faust programming language^K.1by Yann Orlarey et al. at GRAME [61,31] to generate real-time DSP plugins from a high-level specification. In addition to generating efficient inner loops, Faust supports Graphical User Interface (GUI) specification in the source code, and can emit code for various application and plugin environments.^K.2 Moreover, Faust can generate easy-to-read block diagrams directly from the source, illustrating signal flow and processing graphically. This appendix focuses on generating pd, LADSPA, and VST plugins from a simple Faust program specifying a resonator driven by white noise.
