LPC美尔倒谱特征的C源程序
这是我根据赵力那本“语音信号处理”后面的源代码写的LPC美尔倒谱特征的C源代码,
基本上没做什么修改,需要的朋友就可以不用自己再录入了。
程序调试通过,可以直接用。
-LPC Cepstrum C source code is under Zhao The "speech signal processing," the source generation behind code written by LPC Cepstrum

信号频谱分析
1. 观测已知方波信号、正弦波信号的频谱
分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。
2. 观测实时模拟信号(语音)的频谱
用音频设备采集一段语音,将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的,应把它分段分析,而且实际运用中的数字信号处理的FFT的点数是有限的,一般只能达到千点。用傅里叶反变换IFFT,从频域恢复信号。画出频谱图和语音波形图-Signal spectrum analysis
