Implementation of Sound Engine of Gayageum based on INTEL BULVERDE PXA272A Processor

摘要

In this paper, we describe a sound synthesis of Korean plucked string instrument called gayageum, and we propose an implementation of the sound engine based on the Intel Bulverde PXA272A processor. Commuted waveguide synthesis (CWS) is used for physical modeling of gayageum, and modified to include transmission characteristic of movable bridge called Anjok. Characteristics of Anjok are extracted from recorded sound by adaptive filtering for inverse system identification. To implement sound engine of gayageum, we use X-hyper272A board which equips Intel Bulverde PXA272 processor as prototype of sound engine.
