Loading... 学校要举行文艺演出。但悉知学校舞台的背景播放和音频播放分别在两台计算机上，且必须手动切换。为了方便音频的操控，写此程序。 --- StageMusicController - Coco07 - 2021.4.12 帮助你控制播放舞台表演所需的多个.wav音频文件。 平台：Windows7/10 1. StageMusicController.exe需要audio.list文本文件。按照顺序一行一个要播放的.wav文件名。 2. 打开exe可执行文件。回车/右箭头播放下一个音频；左箭头播放上一个音频；空格停止当前音频；数字键（1~9）播放该编号的音频；数字键0回到首个音频前；上/下键控制音量；ESC退出程序。 ```c /* * StageMusicController.c * Coco07 * 2021.4.12 */ #include <windows.h> #include <stdio.h> #include "ccio.h" #define AUDIO_LIST_FILE "audio.list" #define MAX_FILE_NUM 200 #define MAX_FILE_NAME 300 int main(){ system("title StageMusicController - Coco07"); printf("StageMusicController - Coco07 - 2021.4.12\nSimply play .wav audio.\n\n"); FILE *fp = fopen(AUDIO_LIST_FILE, "r"); if(!fp){ printf("Error:Cannot read file \"%s\".\n", AUDIO_LIST_FILE); goto main_ret; } char filelist[MAX_FILE_NUM][MAX_FILE_NAME]; int n = -1; while(!feof(fp)){ fscanf(fp, "%s", filelist[++n]); printf("(%d)%s\n", n+1, filelist[n]); } if(fclose(fp) == EOF){ printf("Error: Cannot close the file \"%s\".\n", AUDIO_LIST_FILE); // goto main_ret; } cprintf(RED, "Now Playing"); cprintf(GREEN, " Coming soon\n"); int i = -1, b = 1; while(i <= n){ if(b){ if(i >= 0) cprintf(RED, "(%d)%s", i+1, filelist[i]); if(i < n) cprintf(GREEN, " (%d)%s", i+2, filelist[i+1]); printf("\n"); b = 0; } for(int key = 8; key <= 255; ++key){ if(GetAsyncKeyState(key)&1){ if((key == VK_RETURN || key == VK_RIGHT) && i < n){ ++i; b = 1; } else if(key == VK_LEFT && i >= 0){ --i; b = 1; } else if(key >= 48 && key <= 57 && key <= 49+n){ i = key-49; b = 1; } else if(key == VK_SPACE){ PlaySound(NULL, NULL, 0); goto while_end; } else if(key == VK_UP){ keybd_event(0xAF, 0, 0, 0); keybd_event(0xAF, 0, KEYEVENTF_KEYUP, 0); } else if(key == VK_DOWN){ keybd_event (0xAE, 0, 0, 0); keybd_event (0xAE, 0, KEYEVENTF_KEYUP, 0); } else if(key == VK_ESCAPE){ goto main_ret; } if(b){ if(i < 0) PlaySound(NULL, NULL, 0); else PlaySound(filelist[i], NULL, SND_FILENAME|SND_ASYNC); goto while_end; } } } while_end:; } cprintf(YELLOW, "END\n"); main_ret: PlaySound(NULL, NULL, 0); system("pause"); return 0; } ``` 这个程序用到了系统音量的调节。最简单的方法就是使用音量调节的虚拟键盘按键。 ```c //音量加 keybd_event (0xAF, 0, 0, 0); keybd_event (0xAF, 0, KEYEVENTF_KEYUP, 0) //音量减 keybd_event (0xAE, 0, 0, 0); keybd_event (0xAE, 0, KEYEVENTF_KEYUP, 0) //静音切换 keybd_event (0xAD, 0, 0, 0); keybd_event (0xAD, 0, KEYEVENTF_KEYUP, 0) ``` 参考文章：https://blog.csdn.net/santook/article/details/10949765 © 允许规范转载 赞赏 如果我的文章对你有用，请随意赞赏 赞赏作者 微信
