Abstract

The Feedback Delay Network (FDN) is used as artificial digital reverberation algorithm. Being one of the most naturally sounding approaches it became widely implemented in many sound processing software products. Although FDN is a very potent tool in regards to artificial reverberation, achieving proper perceptual quality of acoustic simulation usually demands additional modifications to signal processing algorithms within delay lines, as well as on the input/output of FDN. This paper discusses efficient vectorized Architecture for FDN reverberator with policy based design to achieve modular implementation, allowing for compile time construction the FDN, without sacrificing top performance requirements.
