C++中發(fā)聲函數Beep用法

•以前，我聽過一個神犇用C++函數做的音樂，當時的心里就十分激動：哇，好厲害啊，好神啊。

•這次，我終于通過自己無助的盲目的摸索、研究，寫出了這篇文章（此時我的內心是雞凍的233）

下面是正文：

•其實啊，Windows API 就提供了一個這樣奇妙的發(fā)音函數，它就是Beep函數。Beep可以通過控制主板揚聲器的發(fā)聲頻率和節(jié)拍來演奏美妙的旋律，本文根據音樂簡譜來演奏幾首優(yōu)美的歌曲，用以展現(xiàn)Beep的瘋狂魅力。

首先我們來Beep的函數原型：

BOOL Beep(
  DWORD dwFreq; 
  DWORD dwDuration;
);

參數說明：

•dwFreq 指定要發(fā)出的頻率(HZ)
•dwDuration 指定發(fā)音的時長，以毫秒為單位。

Beep的實際應用

•比如說我要發(fā)do這個音，do應該是523hz，且如果要發(fā)一拍的話，就相當于400毫秒。
•那這個函數就成了這樣：Beep(523,400);

•但是，如果我們要連續(xù)的發(fā)出多個音的話，比如說像這樣：

Beep(523,400);//do 
Beep(578,400);//re 
Beep(659,400);//mi

•那豈不是太麻煩了，所以，我建議大家用define函數宏定義一下這些音，比如說這樣：#define re 578和#define mi 659，這樣，上面的三行語句就簡化了成這樣：

Beep(do,400);
Beep(re,400);
Beep(mi,400);

最終，給親們送上一份表（借別人的劃去)
其中，q前綴為低音，1后綴為高音，s前綴為半音階

#define qdo 262 
#define qre 294
#define qmi 330
#define qfa 349
#define qso 392
#define qla 440
#define qsi 494
#define do 523
#define re 578
#define mi 659
#define fa 698
#define so 784
#define la 880
#define si 988
#define do1 1046
#define re1 1175
#define mi1 1318
#define fa1 1480
#define so1 1568
#define la1 1760
#define si1 1976
#define sqdo 277
#define sqre 311
#define sqfa 370
#define sqso 415
#define sqla 466
#define sdo 554
#define sre 622
#define sfa 740
#define sso 831
#define sla 932
#define sdo1 1046
#define sre1 1245
#define sfa1 1480
#define sso1 1661
#define sla1 1865

最后，（嘿，同志們，別跑，后面還有彩蛋呢！）

好吧，是一首用Beep函數演奏的天空之城
