본 논문에서는 저전력 임베디드 DSP를 이용하여 구현되는 실시간 3D 사운드 위치 파악 알고리즘에 대해 설명합니다. 이 구현 방식의 특징은 특정 음원에서 사람의 귀에 이르기까지 다양한 매체를 통한 소리 반사 및 회절 효과 분석에 따라 가청 주파수 대역을 세 개로 분할한다는 것입니다. 저주파수, 중간 주파수, 고주파수 서브밴드에서는 IIR 필터, 파라메트릭 이퀄라이저 및 콤 필터를 각각 사용하여 3D 사운드 위치 파악의 다양한 방식을 고안하여 저전력 임베디드 DSP에서 실시간으로 실행합니다. 이 알고리즘은 저비용, 저전력 소비로 헤드폰을 통해 청취자에게 3D 음향 효과를 제공하는 것을 목표로 합니다.

Abstract: This paper describes a realtime 3D sound localization algorithm to be implemented with the use of a low power embedded DSP. A distinctive feature of this implementation approach is that the audible frequency band is divided into three, in accordance with the analysis of the sound reflection and diffraction effects through different media from a certain sound source to human ears. In the low, intermediate, and high frequency subbands, different schemes of the 3D sound localization are devised by means of an IIR filter, parametric equalizers, and a comb filter, respectively, so as to be run realtime on a low power embedded DSP. This algorithm aims at providing a listener with the 3D sound effects through headphones at low cost and low power consumption.
