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。

AIMI561
This the free version of my Basis of AI Backprop designed to
accompany my not yet published textbook, _The Basis of AI_. This
program contains enough features for students in an ordinary AI or
Neural Networking course. It includes the quickprop and delta-bar-delta
algorithms for faster training and a fast integer version for machines
without floating point hardware.
This particular package includes C source for DOS and UNIX, examples, an
ASCII manual and a number of DOS binaries. The binaries are for systems
with floating point hardware (bp.exe), one for systems without floating
point hardware (bp486sx.exe) and an integer version binary
(ibp486sx.exe) for systems without floating point hardware.
