摘要
针对历史课程视频在录制过程中导致的原始双声道音频信息中的单声道音频信号弱化问题,提出利用主流音频编辑软件增强双声道音频信息的处理方案,简明有效地提升了原始视频的音频质量和可利用性。利用Adobe Audition软件对问题音频信号进行声道分离、信号复制、立体声合成等技术操作,增强弱化信号,生成质量更优的双声道立体声,与课程视频字幕相互补充,促进学习者对课程内容的理解,从而提升原始视频资源的利用程度和传播效应。
As to the problem of the weakening of the audio signal in one track within dual tracks of the original recorded video about the history courses, the author proposed a scheme to enhance the dual channel audio information by using the mainstream audio editing software, which effectively improves the audio quality and availability of the original video. This paper used the audio processing software Adobe Audition to strengthen the weaken signal by operations as channel separation, signal reproduction and stereophonic synthesis. The better two-channel stereo obtained by our method, which supplement with video subtitles, promote the learners to understand the course content better.
