选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。
(2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。
(3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合成信号的时域图形,听一下声音。
(4)对原音频信号进行1024点的分段付立业分析meshgrid
(5)根据主要频线合成音频,并画出时域图形,试听合成效果。
(6)采用线性插值(linspace)和傅立业反变换(fliplr, ifft)分别合成音频,并画出时域图形,试听效果。
