【摘要】：基于當(dāng)前國內(nèi)老電影聲音修復(fù)的現(xiàn)狀——聲音數(shù)字修復(fù)中使用的去噪、編輯等工具需要人工干預(yù)的成分較多,導(dǎo)致聲音修復(fù)效率無法有效提升.本文在數(shù)十部老電影聲音數(shù)字修復(fù)的實踐經(jīng)驗基礎(chǔ)上,分別挑選20世紀(jì)50,60,70,80年代的多部老電影,從中截取數(shù)十段噪聲樣本,對其進(jìn)行分類梳理和噪聲聲學(xué)特點分析,并對每段噪聲給出當(dāng)前常用去噪辦法的說明.本文的研究內(nèi)容為未來電影聲音修復(fù)的算法研發(fā)及相關(guān)研究提供了一份真實可靠、具有借鑒價值的數(shù)據(jù)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.
