目標:

聲音: (4) 音效, (5) 音樂

動作: (1) 讀檔播放, (2) 自動播放 (使用timer計時器鬧鐘會定期響), (3) 內插變得較 smooth

1. 播放聲音 WAV音效 (未壓縮) (使用 PlaySound()函式)

2. 播放音樂 MP3檔 (使用 CMP3_MCI.h, 它是運用 mciSendString()的技巧, 但是我們只要會 Load及Play即可)

以下分別做介紹:

1. 播放聲音 WAV音效 (未壓縮) (使用 PlaySound()函式)

1.1. 重點是分成 前面 #include <Windows.h> 及 #include <mmsystem.h> 之後才能使用PlaySound()

1.2. PlaySound() 的用法是 PlaySound("檔名.wav", NULL, SND_ASYNC);

1.3. 比較一下 SND_ASYNC 及 SND_SYNC 的差別 (ASYNC是不等同步,直接各做各的) (SYNC是要等 PlaySound()整個播完, 才能接下去再做)

#include <stdio.h>

#include <windows.h>

#include <mmsystem.h>

int main()

{

  PlaySound("檔名.wav", NULL, SND_ASYNC);//這行以上才是重點

  printf("Please input a number:\n");

  int n; scanf("%d", &n);//這行只是要卡住的, 別隨便用啊!

}
