  4）读取音乐信号romanza_pe.wav, 截取其前10s信号，选择适当的窗口类型和窗口宽度，显示其短时傅立叶频谱，以便能更清晰地看清谱线。说明信号频谱特点。 5）令D=5下采样音乐信号，播放其声音并显示其短时傅立叶频谱。描述并解释你所听到的声音和观察到的频谱之间的关系() Read the music signal romanza_pe.wav, intercept its first 10 s signal, select the appropriate window type and window width, display its short-time Fourier spectrum, so as to be able to see the spectrum lines more clearly. The characteristics of signal spectrum are explained. 5) let D=5 sample the music signal, play its voice and display its short-time Fu Liye spectrum. Describe and explain the relationship between the voice you hear and the observed spectrum.)
