문제

Java와 함께 *.wav 파일을 재생하려고합니다. 다음을 수행하기를 원합니다.
버튼을 누르면 짧은 경고음 소리를냅니다.

Googled를 보았지만 대부분의 코드는 작동하지 않았습니다. 누군가 나에게 .wav 파일을 재생하기 위해 간단한 코드 스 니펫을 줄 수 있습니까?

도움이 되었습니까?

해결책

마침내 나는 다음을 수행 할 수 있었고 잘 작동합니다.

import java.io.File;
import java.io.IOException;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;

public class MakeSound {

    private final int BUFFER_SIZE = 128000;
    private File soundFile;
    private AudioInputStream audioStream;
    private AudioFormat audioFormat;
    private SourceDataLine sourceLine;

    /**
     * @param filename the name of the file that is going to be played
     */
    public void playSound(String filename){

        String strFilename = filename;

        try {
            soundFile = new File(strFilename);
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }

        try {
            audioStream = AudioSystem.getAudioInputStream(soundFile);
        } catch (Exception e){
            e.printStackTrace();
            System.exit(1);
        }

        audioFormat = audioStream.getFormat();

        DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
        try {
            sourceLine = (SourceDataLine) AudioSystem.getLine(info);
            sourceLine.open(audioFormat);
        } catch (LineUnavailableException e) {
            e.printStackTrace();
            System.exit(1);
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }

        sourceLine.start();

        int nBytesRead = 0;
        byte[] abData = new byte[BUFFER_SIZE];
        while (nBytesRead != -1) {
            try {
                nBytesRead = audioStream.read(abData, 0, abData.length);
            } catch (IOException e) {
                e.printStackTrace();
            }
            if (nBytesRead >= 0) {
                @SuppressWarnings("unused")
                int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
            }
        }

        sourceLine.drain();
        sourceLine.close();
    }
}

다른 팁

다음은 태양을 사용하지 않고 올 수있는 가장 우아한 형태입니다.*:

import java.io.*;
import javax.sound.sampled.*;

try {
    File yourFile;
    AudioInputStream stream;
    AudioFormat format;
    DataLine.Info info;
    Clip clip;

    stream = AudioSystem.getAudioInputStream(yourFile);
    format = stream.getFormat();
    info = new DataLine.Info(Clip.class, format);
    clip = (Clip) AudioSystem.getLine(info);
    clip.open(stream);
    clip.start();
}
catch (Exception e) {
    //whatevers
}

가장 짧은 양식 (임의의 라이브러리를 설치할 필요없이)?

public static void play(String filename)
{
    try
    {
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(new File(filename)));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

유일한 문제는 *.wav 마감 후이 방법을 차단하여 데이터를 닫고 폐기하는 좋은 방법이 없다는 것입니다.clip.drain() 차단 중이지만 그렇지 않습니다. 클립이 실행되지 않습니다 직후 start(). 유일한 일이지만 못생긴 내가 찾은 방법은 다음과 같습니다.

// ...
clip.start();
while (!clip.isRunning())
    Thread.sleep(10);
while (clip.isRunning())
    Thread.sleep(10);
clip.close();

이벤트 리스너를 사용하여 클립을 재생 한 후 클립을 닫을 수 있습니다.

import java.io.File;
import javax.sound.sampled.*;

public void play(File file) 
{
    try
    {
        final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));

        clip.addLineListener(new LineListener()
        {
            @Override
            public void update(LineEvent event)
            {
                if (event.getType() == LineEvent.Type.STOP)
                    clip.close();
            }
        });

        clip.open(AudioSystem.getAudioInputStream(file));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

스 니펫 여기 Windows 사운드로 테스트 된 잘 작동합니다.

public static void main(String[] args) {
        AePlayWave aw = new AePlayWave( "C:\\WINDOWS\\Media\\tada.wav" );
        aw.start();     
}

WAV 파일을 재생하는 클래스, 소리가 재생이 끝날 때까지 차단합니다.

class Sound implements Playable {

    private final Path wavPath;
    private final CyclicBarrier barrier = new CyclicBarrier(2);

    Sound(final Path wavPath) {

        this.wavPath = wavPath;
    }

    @Override
    public void play() throws LineUnavailableException, IOException, UnsupportedAudioFileException {

        try (final AudioInputStream audioIn = AudioSystem.getAudioInputStream(wavPath.toFile());
             final Clip clip = AudioSystem.getClip()) {

            listenForEndOf(clip);
            clip.open(audioIn);
            clip.start();
            waitForSoundEnd();
        }
    }

    private void listenForEndOf(final Clip clip) {

        clip.addLineListener(event -> {
            if (event.getType() == LineEvent.Type.STOP) waitOnBarrier();
        });
    }

    private void waitOnBarrier() {

        try {

            barrier.await();
        } catch (final InterruptedException ignored) {
        } catch (final BrokenBarrierException e) {

            throw new RuntimeException(e);
        }
    }

    private void waitForSoundEnd() {

        waitOnBarrier();
    }
}

함께하는 또 다른 방법 AudioInputStream:

import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.Line;
import javax.sound.sampled.LineEvent;
import javax.sound.sampled.LineListener;
import javax.swing.JDialog;
import javax.swing.JFileChooser;

public class CoreJavaSound extends Object implements LineListener {
    File soundFile;

    JDialog playingDialog;

    Clip clip;

    public static void main(String[] args) throws Exception {
        CoreJavaSound s = new CoreJavaSound();
    }

    public CoreJavaSound() throws Exception {
        JFileChooser chooser = new JFileChooser();
        chooser.showOpenDialog(null);
        soundFile = chooser.getSelectedFile();

        System.out.println("Playing " + soundFile.getName());

        Line.Info linfo = new Line.Info(Clip.class);
        Line line = AudioSystem.getLine(linfo);
        clip = (Clip) line;
        clip.addLineListener(this);
        AudioInputStream ais = AudioSystem.getAudioInputStream(soundFile);
        clip.open(ais);
        clip.start();
    }

    public void update(LineEvent le) {
        LineEvent.Type type = le.getType();
        if (type == LineEvent.Type.OPEN) {
            System.out.println("OPEN");
        } else if (type == LineEvent.Type.CLOSE) {
            System.out.println("CLOSE");
            System.exit(0);
        } else if (type == LineEvent.Type.START) {
            System.out.println("START");
            playingDialog.setVisible(true);
        } else if (type == LineEvent.Type.STOP) {
            System.out.println("STOP");
            playingDialog.setVisible(false);
            clip.close();
        }
    }
}

Java 반사가없는 솔루션 DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)

Java 반사는 성능을 감소시킵니다. 실행하려면 : java playsound absoluteFilePathTo/file.wav

import javax.sound.sampled.*;
import java.io.*;
public class playsound {

    public static void main (String args[]) throws Exception {
        playSound (args[0]);
    }

    public static void playSound () throws Exception {
        AudioInputStream 
        audioStream = AudioSystem.getAudioInputStream(new File (filename));

        int BUFFER_SIZE = 128000;
        AudioFormat audioFormat = null;
        SourceDataLine sourceLine = null;

        audioFormat = audioStream.getFormat();

        sourceLine = AudioSystem.getSourceDataLine(audioFormat);
        sourceLine.open(audioFormat);
        sourceLine.start();

        int nBytesRead = 0;
        byte[] abData = new byte[BUFFER_SIZE];
        while (nBytesRead != -1) {
            try {
                nBytesRead = 
                audioStream.read(abData, 0, abData.length);
            } catch (IOException e) {
                e.printStackTrace();
            }

            if (nBytesRead >= 0) {
                int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
            }
        }

        sourceLine.drain();
        sourceLine.close();
    }

}

이 방법으로도 오디오 스트림을 사용할 수 있습니다.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

import sun.audio.AudioPlayer;
import sun.audio.AudioStream;

public class AudioWizz extends JPanel implements ActionListener {

    private static final long serialVersionUID = 1L; //you like your cereal and the program likes their "serial"

    static AudioWizz a;
    static JButton playBuddon;
    static JFrame frame;

    public static void main(String arguments[]){

        frame= new JFrame("AudioWizz");
        frame.setSize(300,300);
        frame.setVisible(true);
        a= new AudioWizz();
        playBuddon= new JButton("PUSH ME");
        playBuddon.setBounds(10,10,80,30);
        playBuddon.addActionListener(a);

        frame.add(playBuddon);
        frame.add(a);
    }

    public void actionPerformed(ActionEvent e){ //an eventListener
        if (e.getSource() == playBuddon) {
            try {
                InputStream in = new FileInputStream("*.wav");
                AudioStream sound = new AudioStream(in);
                AudioPlayer.player.start(sound);
            } catch(FileNotFoundException e1) {
                e1.printStackTrace();
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }
    }
