ding
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。

ROC-plot.zip
试者工作特征曲线 (receiver operating characteristic curve,简称ROC曲线),又称为感受性曲线(sensitivity curve)。得此名的原因在于曲线上各点反映着相同的感受性,它们都是对同一信号刺激的反应,只不过是在几种不同的判定标准下所得的结果而已。接受者操作特性曲线就是以虚报概率为横轴,击中概率为纵轴所组成的坐标图,和被试在特定刺激条件下由于采用不同的判断标准得出的不同结果画出的曲线。(PLOTROC Plot receiver operating characteristic.
Syntax
plotroc(targets,outputs)
plotroc(targets1,outputs1, name1 ,targets,outputs2, name2 , ...)
Description
PLOTROC(TARGETS,OUTPUTS) plots the receiver operating characteristic
for each output class. The more each curve hugs the left and top edges
of the plot, the better the classification.
PLOTROC(TARGETS1,OUTPUTS2, name1 ,...) generates multiple plots.
