当我们听到电脑上出现美妙的旋律的时候,是不是发现这是一个很伟大的开发,这就是C语言中Beep,下面爱站技术频道小编就给大家介绍C++中发声函数Beep用法。

下面是正文:

•其实啊,Windows API 就提供了一个这样奇妙的发音函数,它就是Beep函数。Beep可以通过控制主板扬声器的发声频率和节拍来演奏美妙的旋律,本文根据音乐简谱来演奏几首优美的歌曲,用以展现Beep的疯狂魅力。

首先我们来Beep的函数原型:

BOOL Beep(
  DWORD dwFreq; 
  DWORD dwDuration;
); 

参数说明:

•dwFreq 指定要发出的频率(HZ)
•dwDuration 指定发音的时长,以毫秒为单位。

Beep的实际应用

•比如说我要发do这个音,do应该是523hz,且如果要发一拍的话,就相当于400毫秒。
•那这个函数就成了这样:Beep(523,400);

•但是,如果我们要连续的发出多个音的话,比如说像这样:

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



•那岂不是太麻烦了,所以,我建议大家用define函数宏定义一下这些音,比如说这样:#define re 578和#define mi 659,这样,上面的三行语句就简化了成这样:

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

最终,给亲们送上一份表(借别人的 划去)
其中,q前缀为低音,1后缀为高音,s前缀为半音阶

#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,同志们,别跑,后面还有彩蛋呢!)

好吧,是一首用Beep函数演奏的天空之城
