//Time:2016/08/04


#include <stdio.h>
#include <stdlib.h>


int main (void)
{
unsigned char* psTest = (unsigned char*)malloc(2); //截取数据的缓冲区
int tmp = 0;
int begin_time = 0; //开始截取的位置
int run_time = 0; //准备截取的长度


FILE* fp = fopen("music_test.pcm","rb+"); //原文件
FILE* fp_cut = fopen("cut_music.pcm","wb+");
