基于球麦克风阵列的高阶声场记录与重放在电影音频制作中的应用
Higher order sound field recording and reproduction based on spherical micro-phone array for film audio production
摘要
Abstract
With the demand for development of ultra immersive audio-visual experiences in film,immersive sound field re-cording and reproduction technologies have become increasingly important.This paper focuses on the issues of sound field recording and reproduction in film audio production technology.It introduces the higher order ambisonics(HOA)analy-sis technology based on spherical microphone arrays.Solutions are provided for the problems of low-frequency noise and high-frequency aliasing in spherical harmonic decomposition of spherical microphone arrays,as well as the order limitation in binaural reproduction technology.Research shows that the solutions can provide audiences with more realistic and im-mersive sound field reproduction effects,enhancing the cinema experience and having broad application prospects in film audio production.关键词
