Java中的声音问题 [英] Sound problems in Java

问题描述

我对使用Java播放声音有一些疑问，我希望你能帮助我。

1.如何使用停止按钮停止播放声音？

2.如何减慢（或冷却时间）声音？

3.我想创建一个可以调节音量和静音选项的选项框架，我该怎么做？

这是我的代码：

I have some questions about playing sound in Java and I hope you can help me out.
1. How can I stop a playing sound with a "Stop" button?
2. How can I slow down (or cooldown time) a sound?
3. I want to create a option frame where I can adjust volume and have mute option, how can I do that?
This is my code:

    private void BGM() {
        try {
            File file = new File(AppPath + "\\src\\BGM.wav");
            Clip clip = AudioSystem.getClip();
            clip.open(AudioSystem.getAudioInputStream(file));
            clip.start();
        } catch (Exception e) {
            System.err.println(e.getMessage());
        }
    }  

任何帮助将不胜感激，并且，有一个美好的一天！

Any help will be greatly appreciated, and, Have a nice day!

推荐答案

您正在使用面向对象的编程语言，所以让我们利用它并封装管理剪辑/音频变成一个简单的类......

You're working in an Object Oriented programming lanuage, so let's take advantage of that and encapsulate the management of the clip/audio into a simple class...

public class AudioPlayer {

    private Clip clip;

    public AudioPlayer(URL url) throws IOException, LineUnavailableException, UnsupportedAudioFileException {
        clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(url.openStream()));
    }

    public boolean isPlaying() {
        return clip != null && clip.isRunning();
    }

    public void play() {
        if (clip != null && !clip.isRunning()) {
            clip.start();
        }
    }

    public void stop() {
        if (clip != null && clip.isRunning()) {
            clip.stop();
        }
    }

    public void dispose() {
        try {
            clip.close();
        } finally {
            clip = null;
        }
    }

}

现在，要使用它，你需要创建一个类实例字段，它允许你从你想要使用它的类中的任何地方访问它...

Now, to use it, you need to create a class instance field which will allow you to access the value from anywhere within the class you want to use it...

private AudioPlayer bgmPlayer;

然后，当你需要它时，你创建一个 AudioPlayer的实例并将其分配给此变量

Then, when you need it, you create an instance of AudioPlayer and assign it to this variable

try {
    bgmPlayer = new AudioPlayer(getClass().getResource("/BGM.wav"));
} catch (IOException | LineUnavailableException | UnsupportedAudioFileException ex) {
    ex.printStackTrace();
}

现在，当您需要时，只需拨打 bgmPlayer.play（）或 bgmPlayer.stop（）

Now, when you need to, you simply call bgmPlayer.play() or bgmPlayer.stop()
