播放WAV檔

#include <windows.h>
#include <mmsystem.h>                                                 playsound函式
int main()
{
    PlaySoundA("ccheer.wav", NULL, SND_SYNC);
                            檔名             空        聲音同步
}
檔案要存在freeglut\bin裡面

進階

#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
void display()
{
}
void keyboard(unsigned char key,int x, int y)
{
    if(key=='1')PlaySoundA("do.wav", NULL, SND_ASYNC);           不同步，不等結束，繼續
    if(key=='2')PlaySoundA("re.wav", NULL, SND_ASYNC);
    if(key=='3')PlaySoundA("mi.wav", NULL, SND_ASYNC);
    if(key=='4')PlaySoundA("fa.wav", NULL, SND_ASYNC);
    if(key=='5')PlaySoundA("so.wav", NULL, SND_ASYNC);
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("week12");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);                                                               鍵盤函式
    glutMainLoop();
}

導入mp3

CMP3_MCI.h老師給的mp3程式

丟入相同路徑

#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"                       雙引號，專案在同一個目錄
CMP3_MCI mp3;                                   宣告變數，mp3
void display()
{
}
void keyboard(unsigned char key,int x, int y)
{
    if(key=='1')PlaySoundA("do.wav", NULL, SND_ASYNC);
    if(key=='2')PlaySoundA("re.wav", NULL, SND_ASYNC);
    if(key=='3')PlaySoundA("mi.wav", NULL, SND_ASYNC);
    if(key=='4')PlaySoundA("fa.wav", NULL, SND_ASYNC);
    if(key=='5')PlaySoundA("so.wav", NULL, SND_ASYNC);
}
int main(int argc,char**argv)
{
    mp3.Load("music.mp3");
    mp3.Play();
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("week12");
    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}

把單音符變合弦

#include <windows.h>
#include <mmsystem.h>
#include <GL/glut.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
CMP3_MCI Do,Re,Mi,Fa,So;                                五個物件變數
void display()
{

}
void keyboard(unsigned char key,int x, int y)
{
    if(key=='1')Do.Play();///PlaySoundA("do.wav", NULL, SND_ASYNC);      可有合弦
    if(key=='2')Re.Play();///PlaySoundA("re.wav", NULL, SND_ASYNC);
    if(key=='3')Mi.Play();///PlaySoundA("mi.wav", NULL, SND_ASYNC);
    if(key=='4')Fa.Play();///PlaySoundA("fa.wav", NULL, SND_ASYNC);
    if(key=='5')So.Play();///PlaySoundA("so.wav", NULL, SND_ASYNC);
}
int main(int argc,char**argv)
{
    Do.Load("do.wav"); Re.Load("Re.wav"); Mi.Load("Mi.wav");          五個變數 設好檔案
    Fa.Load("Fa.wav"); So.Load("So.wav");
    mp3.Load("music.mp3");
    ///mp3.Play();
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("week12");

    glutDisplayFunc(display);
    glutKeyboardFunc(keyboard);

    glutMainLoop();
}

整合檔案

把.cbp的檔案路徑刪除

拉進 freeglut.dll 就可以把其他檔案整合在同一個資料夾
