噪声特点分析在老电影声音数字修复中的应用
发布时间：2019-07-30 08:41
【摘要】：基于当前国内老电影声音修复的现状——声音数字修复中使用的去噪、编辑等工具需要人工干预的成分较多,导致声音修复效率无法有效提升.本文在数十部老电影声音数字修复的实践经验基础上,分别挑选20世纪50,60,70,80年代的多部老电影,从中截取数十段噪声样本,对其进行分类梳理和噪声声学特点分析,并对每段噪声给出当前常用去噪办法的说明.本文的研究内容为未来电影声音修复的算法研发及相关研究提供了一份真实可靠、具有借鉴价值的数据支持.
[Abstract]:Based on the current situation of sound repair in old films in China, there are many tools such as denoising and editing, which need manual intervention, so that the efficiency of sound repair can not be effectively improved. On the basis of the practical experience of sound digital restoration of dozens of old films, this paper selects many old films in the 1950s, 60th and 1980s respectively, intercepts dozens of noise samples from them, classifies and combs them and analyzes the acoustic characteristics of noise, and gives an explanation of the common denoising methods for each segment of noise. The research content of this paper provides a real and reliable data support for the future research and development of film sound repair algorithm and related research.
