摘要
以多小波的多分辨分析为理论基础,以Windows XP启动声为原始音频信号,在MATLAB环境下研究C-L多小波在音频信号分解重构中的应用。通过实验,实现多小波对双声道信号的每一声道分别进行分解,再重构为双声道音频信号,为下一步研究提供基础。
It was based on multiresolution analysis of multiwavelet here,took Windows XP start sound as original sound signal,and studied the application of C-L multiwavelet in audio signal decomposition and reconstruction under MATLAB.Through experiment,multiwavelet can decompose each sound track for dual track signal and rebuild into dual track sound signal.Offering base for further research,our studying direction is that remove noise from sound signal under MATLAB and deal with video signal,as well as the effect of multiwavelet property on signal processing.
