摘要
MATLAB GUI是MATLAB用户用于算法开发、数据可视化的交互式环境,通过GUI生成的操作界面可以使用户不用浏览烦冗的代码而进行操作。文章基于数字信号处理和MATLAB,运用图形可视化工具GUI,完成了从倒谱分析出发的数字语音篡改检测界面平台,进行语音的录制,研究了在拼接不同采样率的音频下时域波形、频域波形、倒谱图和声道冲激响应频谱的变化,更直观地分析待检测的语音信号的篡改情况。
MATLAB GUI is an interactive environment used by MATLAB users for algorithm development and data visualization.The operation interface generated by GUI enables users to operate without browsing the complicated code.Based on digital signal processing and MATLAB,this paper completes the digital voice tampering detection interface platform from cepstrum analysis by using GUI which is a graphic visualization tool.It records the voice,and studies the changes of time domain waveform,frequency domain waveform,cepstrum map and channel impulse response spectrum when splicing different sampling rates of audio,so as to more intuitively analyze the tampering situation of the voice signal to be detected.
