Implementation of high-performance sound synthesis engine for plucked-string instruments

Abstract

This paper implements a high-performance sound synthesis engine for plucked-string instruments. To do this, we evaluate the impact of sample-per-processing-element (SPE) ratios on system performance, area efficiency, and energy efficiency. Experimental results for the sound synthesis algorithm of acoustic and classical guitars indicate that the highest area efficiency and energy efficiency are achieved at SPE ratio=5,513 (PEs=48) and 2,756 (PEs=96), respectively, for the acoustic guitar. For the classical guitar, the maximum area efficiency and energy efficiency are achieved at SPE ratio=22,050 (PEs=12) and 5,513 (PEs=48), respectively. The synthetic sounds using the reference multi-core processor were very similar to original sounds sampled at 44.1 kHz. © 2011 Springer-Verlag.
