摘　　要：数字音频修复用于恢复或改进损坏的音频信号,是一个重要的研究领域。该文对数字音频修复进行介绍,以及对现阶段的一些高级数字音频修复算法进行阐述。数字音频修复的目的是从存在噪声、失真和混响等干扰的音频信号中恢复原始音频效果。传统的音频修复方法主要是基于滤波器、频率域、时域等方法,具有处理速度快和低廉等优点。但是,这些方法容易破坏信号的信噪比、动态范围和频谱信息等方面的前置条件,也不能很好地处理复杂的音频噪声和失真问题,导致音频质量下降。因此,研究人员逐渐转向使用更先进的数字信号处理技术来解决这些问题。Digital audio repair is used to recover or improve damaged audio signals,which is an important research field.This paper gives a brief introduction to the digital audio repair,as well as some advanced digital audio repair algorithms at the present stage.The purpose of digital audio repair is to restore the original audio effect from audio signals with noise,distortion and reverberation.The traditional audio repair methods are mainly based on filter,frequency domain,time domain and so on,which have the advantages of fast processing speed and low cost.However,these methods are easy to destroy the preconditions of signal-to-noise ratio,dynamic range and spectrum information,and can not well deal with complex audio noise and distortion,resulting in the decline of audio quality.As a result,researchers are gradually turning to more advanced digital signal processing technologies to solve these problems.
