VC 用发音函数Beep()播放简谱音乐

来源：互联网发布：建筑数据编辑：程序博客网时间：2024/04/20 02:12

Win32 API中有个非常有意思的发音函数Beep()，可以用它在扬声器上播放简单的音调，如果按简谱来设置播放的内容，就可以播放一些简单的音乐了。

函数原型：

BOOL WINAPI Beep(

__in DWORD dwFreq,

__in DWORD dwDuration

);

函数说明：

第一个参数表示频率，用Hz为单位，可以在0x25到0x7FFF之间。

第二个参数表示持续的时间，以毫秒为单位。

与这个函数类似的是：

BOOL WINAPI MessageBeep(

__in UINT uType

);

这个函数使用要广泛的多。相当多的程序在MessageBox()之前都会调用MessageBeep()来发出一些提示音（实际上是播放系统音乐文件）。

可供选择的参数有：

MB_ICONASTERISK
0x00000040L

SystemAsterisk

MB_ICONEXCLAMATION
0x00000030L

SystemExclamation

MB_ICONHAND
0x00000010L

SystemHand 警告音

MB_ICONQUESTION
0x00000020L

SystemQuestion

MB_OK
0x00000000L

SystemDefault

再附上本人收藏的几个用Beep()播放音乐的程序，虽然音质无法与音频文件媲美，但做个小小的娱乐还是可以的：

// 播放生日快乐

#include <windows.h>

void main(void)

{

unsigned FREQUENCY[] = {392,392,440,392,523,494,

392,392,440,392,587,523,

392,392,784,659,523,494,440,

689,689,523,587,523};

unsigned DELAY[] = {375,125,500,500,500,1000,

375,125,500,500,500,1000,

375,125,500,500,500,500,1000,

375,125,500,500,500,1000};

int i;

for (i = 0; i < 25; i++)

{

Beep(FREQUENCY[i],DELAY[i]);

}

// 播放小酒窝
