音频编辑处理系统的设计与实现

Design and Implementation of Audio Editing and Processing

介绍了一个由上载模块、编辑模块、播放模块以及下载模块组成的数字音频非线性编辑系统。具体介绍了3个有代表性的音频特技的原理和实现。这些特技可以单独使用也可以组合使用,以满足音频编辑的各种要求。文中提出的音频非线性编辑模块可以和视频非线性编辑模块以及其它设备一起构成完整的非线性编辑系统。

In this paper,A digital audio nonlinear-editing system composed of upload model,editing model,playback model and download model is introduced.Algorithms and implementation of three typical audio effects(e-qualization,dynamic compression and expansion)are emphasized.These audio effects can be used independently or in combination to meet all kinds of demands in audio editing.Audio nonlinear-editing model proposed in this pa-per can be combined with video nonlinear editing model and other equipment to become a complete nonlinear editing system.
