有没有办法立即播放声音? [英] Is there a way to play a sound without delay?

问题描述

我的程序正在播放声音PlaySound.

程序运行正常，我可以听到声音，但是当歌曲结束时，有大约 1 秒的延迟，然后歌曲再次播放.

我问过谷歌，他给了我这个问题 - PlaySound() Delay

回答的人说，我们需要使用 SND_ASYNC 而不是 SND_SYNC，我听他说并做了，但我什么也听不到.>

你有什么建议吗?

顺便说一句，这是我目前用于这个项目的歌曲 - Nyan Cat

我希望这首歌立即重新开始，让用户听不到有延迟.

最终代码:

#include #include #include <字符串>#pragma 注释(lib，winmm.lib")int main(){std::string pathtosound = "C:\\Users\\roile\\Documents\\Dragonite\\nyan.wav";而(真){播放声音(pathtosound.c_str()，0，SND_SYNC)；}返回0；}

解决方案

SND_LOOP 标志在 Microsoft Docs:

<块引用>

声音重复播放，直到 PlaySound 被再次调用pszSound 参数设置为 NULL.如果设置了这个标志，你还必须设置SND_ASYNC 标志.

请注意最后一句，因此以下代码可能会更好:

#include #include #include <字符串>#pragma 注释(lib，winmm.lib")int main(){std::string pathtosound = "C:\\Users\\roile\\Documents\\Dragonite\\nyan.wav";播放声音(pathtosound.c_str(), 0, SND_ASYNC | SND_LOOP);而(真){//在某一点停止循环}播放声音(NULL, 0, 0);//停止采样返回0；}

My program is playing a sound PlaySound.

The program works fine and I can hear the sound, but when the song end, there is a delay for like 1 second, and then the song play again.

I asked Google, and he gave me this question - PlaySound() Delay

The guy who answerd , said that instead SND_SYNC we need to use SND_ASYNC, I listened to him and did it, but I can't hear anything.

Do you have any suggestions ?

Btw, this is the song I'm currently using for this project - Nyan Cat

I want that this song will be start again immediately, for the user to not hear that there is a Delay.

Final Code:

#include <iostream>
#include <Windows.h>
#include <string>
#pragma comment(lib, "winmm.lib")

int main()
{
    std::string pathtosound = "C:\\Users\\roile\\Documents\\Dragonite\\nyan.wav";
    while (true) {
        PlaySound(pathtosound.c_str(), 0, SND_SYNC);
    }

    return 0;
}

解决方案

The SND_LOOP flag is described as follows in Microsoft Docs:

The sound plays repeatedly until PlaySound is called again with the pszSound parameter set to NULL. If this flag is set, you must also set the SND_ASYNC flag.

Pay attention to the last sentence, hence the following code will probably work better:

#include <iostream>
#include <Windows.h>
#include <string>
#pragma comment(lib, "winmm.lib")

int main()
{
    std::string pathtosound = "C:\\Users\\roile\\Documents\\Dragonite\\nyan.wav";
    PlaySound(pathtosound.c_str(), 0, SND_ASYNC | SND_LOOP);
    while (true) {
        // Stop loop at some point
    }
    PlaySound(NULL, 0, 0);  // Stop sample

    return 0;
}
