自己写的一个基于eMbedded Visual C++的音频采集以及频谱分析小程序。 包括录音，回放，时域波形，频谱图-Based on the eMbedded Visual C++ of the audio spectrum analysis procedures. Including recording, playback, time-domain waveform, frequency spectrum

裸机s3c2440实现频率计（用定时器0定时间1s，外部频率输入用外部中断计数），使用EINT8引脚，使用mini2440开发板-Bare metal s3c2440 achieve frequency meter (with timer 0 set time 1s, external frequency input with an external interrupt counts), use EINT8 pin, using mini2440 development board

wolf calculated Lyapunov exponent, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. MinkowskiMethod algorithm.
