基于matlab语音短时频谱分析，到谱分析，语谱图分析及结果(Short-time spectrum analysis based on matlab speech to the spectral analysis, spectrogram analysis and results)

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)

说明：  CST MATLAB 联合仿真超材料开口谐振环单元(CST matlab joint simulation of open resonance ring element of super material)

here these are the compiled files.
