我应该为java使用什么音频格式？

Question

我正在制作一个基于Java的游戏,我想添加一些声音效果.我搜查了一下,发现自己更加困惑.我知道编码因文件格式而异.我只需要一些声音 - 无论哪种格式都无关紧要.所以请建议我最简单的文件格式.代码段非常有用.

什么是最简单的格式和提供音效的方法？

Answer 1

对于短音,你应该使用WAV或AU,WAV是最小的声音格式.我刚完成这个小程序,你需要做的就是有一个.wav声音.

此程序生成一个带按钮的窗口,每次单击该按钮时,都会播放指定的声音.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import java.net.URL;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
import javax.swing.JButton;
import javax.swing.JFrame;

public class PlaySound extends JFrame{

    private Clip clip;

    public static void main(String [] args) {

        PlaySound app = new PlaySound();

    }

    public PlaySound() {
        JButton play = new JButton("Play");//here we make the button
        play.addActionListener(new ActionListener() {//here we tell what the button will do
        public void actionPerformed(ActionEvent e) {
            playTheSound();//when its clicked call this method
        }
    });

    this.add(play);
    this.pack();
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    this.setVisible(true);
}

private void SoundEffect(URL url) {
    try {
        // Set up an audio input stream piped from the sound file.
        AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(url);
        // Get a clip resource.
        clip = AudioSystem.getClip();
        // Open audio clip and load samples from the audio input stream.
        clip.open(audioInputStream);
    } catch (UnsupportedAudioFileException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (LineUnavailableException e) {
        e.printStackTrace();
    }
}

// Play or Re-play the sound effect from the beginning, by rewinding.
public void playTheSound() {

    URL url = getClass().getResource("click.wav");//You can change this to whatever other sound you have
    SoundEffect(url);//this method will load the sound

    if (clip.isRunning())
        clip.stop();   // Stop the player if it is still running
    clip.setFramePosition(0); // rewind to the beginning
    clip.start();     // Start playing

    }

}

您可以随时更改"click.wav"以获取其他声音,包括.au文件.

Answer 2

正如mikera和Basilio德国人所说,AU和WAV都是游戏中使用的短音效的好选择.当前的JRE支持返回的类型AudioSystem.getAudioFileTypes(),但我会坚持使用其中的一个.

本Clip类提供简单的方法来加载和播放声音字节.

举个例子,这里是Java Sound信息的例子.页面.

import java.net.URL;
import javax.swing.*;
import javax.sound.sampled.*;

public class LoopSound {

    public static void main(String[] args) throws Exception {
        URL url = new URL(
            "http://pscode.org/media/leftright.wav");
        Clip clip = AudioSystem.getClip();
        // getAudioInputStream() also accepts a File or InputStream
        AudioInputStream ais = AudioSystem.
            getAudioInputStream( url );
        clip.open(ais);
        // loop continuously
        clip.loop(-1);
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                // A GUI element to prevent the Clip's daemon Thread
                // from terminating at the end of the main()
                JOptionPane.showMessageDialog(null, "Close to exit!");
            }
        });
    }
}
