请认真阅读采用MATLAB分析WAV文件。

步骤一：选择一个WAV文件作为分析的对象 。（ding.wav）

步骤三：进行 FFT变换并画频域图形 。

步骤四：进行该声波主要频谱的分析。

步骤五：根据该声音的频谱，反演时域图形 。（有失真）

步骤六：进行付立叶逆变换IFFT并画频域图形 。-Please carefully read the WAV files using MATLAB analysis. Step One: Select a WAV file as the target of analysis. (Ding.wav) Step Three: Transform and painting to FFT frequency domain graphics. Step four: the main frequency spectrum of the acoustic analysis. Step 5: According to the sound spectrum, inversion of time-domain graphics. (With distortion) Step six: to carry out inverse Fourier transform frequency domain IFFT and painted graphics.
