声音采样剪辑

Question

嗨，我正在尝试制作一个播放一首歌曲，然后暂停或关闭以换成另一首歌曲的应用程序！

这是我的完整项目！

公共类SimpleAudioPlayer {

Long currentFrame;
Clip clip;

//status of the clip
String status;

AudioInputStream audioInputStream;
static String filePath;

// constructor to initialize streams and clip 
    public SimpleAudioPlayer(String filePath) 
        throws UnsupportedAudioFileException, 
        IOException, LineUnavailableException 
    { 
        // create AudioInputStream object 
        audioInputStream = 
                AudioSystem.getAudioInputStream(new File(filePath).getAbsoluteFile()); 

        // create clip reference 
        clip = AudioSystem.getClip(); 

        // open audioInputStream to the clip 
        clip.open(audioInputStream); 

        clip.loop(Clip.LOOP_CONTINUOUSLY); 


    } 




    public void play() 
    { 

        clip.start(); 

        status = "play"; 
    } 


    public void pause() 
    { 
        if (status.equals("paused")) 
        { 
            System.out.println("audio is already paused"); 
            return; 
        } 
        this.currentFrame = 
        this.clip.getMicrosecondPosition();

        { 
            System.out.println("Audio is already "+ 
            "being played"); 
            return; 
        } 
        clip.close(); 
        resetAudioStream(); 
        clip.setMicrosecondPosition(currentFrame); 
        this.play(); 
    } 

    // Method to restart the audio 
    public void restart() throws IOException, LineUnavailableException, 
                                            UnsupportedAudioFileException 
    { 
        clip.stop(); 
        clip.close(); 
        resetAudioStream(); 
        currentFrame = 0L; 
        clip.setMicrosecondPosition(0); 
        this.play(); 
    } 

    // Method to stop the audio 
    public void stop() throws UnsupportedAudioFileException, 
    IOException, LineUnavailableException 
    { 
        currentFrame = 0L; 
        clip.stop(); 
        clip.close(); 
        System.out.println("Stoped");
    } 

    IOException, 
                                                        LineUnavailableException 
    { 
        if (c > 0 && c < clip.getMicrosecondLength()) 
        { 
            clip.stop(); 
            clip.close(); 
            resetAudioStream(); 
            currentFrame = c; 
            clip.setMicrosecondPosition(c); 
            this.play(); 
        } 
    } 


    public void resetAudioStream() throws UnsupportedAudioFileException, IOException, 
                                            LineUnavailableException 
    { 
        audioInputStream = AudioSystem.getAudioInputStream( 
        new File(filePath).getAbsoluteFile()); 
        clip.open(audioInputStream);

//我这个项目的主要Gui

公共类MainGui扩展JFrame实现ActionListener {

static final int FRAME_WIDTH = 1200;     静态最终int FRAME_HEIGHT = 800;

JButton exit, stop, s1, s2, s3, s4;

 JLabel background;


 MainGui(String title) {
     super(title);
     setLayout(null);




     setVisible(true);
     setSize(FRAME_WIDTH, FRAME_HEIGHT);
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);





     //gif
     Icon imgIcon = new ImageIcon(this.getClass().getResource("gifs/giphy.gif"));
     JLabel label = new JLabel(imgIcon);
     label.setBounds(FRAME_WIDTH/2 -300, FRAME_HEIGHT - 800, 600, 500);
     getContentPane().add(label);
     setBackground(Color.DARK_GRAY);





     //Song Butons

     s1 = new JButton("Hooked on a Feeling");
     this.add(s1);
     s1.setBounds(FRAME_WIDTH/2 -100  ,FRAME_HEIGHT -200, 200, 50 );
     s1.addActionListener(this);

     s2 = new JButton("I Want You Back");
     this.add(s2);
     s2.setBounds(FRAME_WIDTH/2-100, FRAME_HEIGHT- 150, 200, 50);
     s2.addActionListener(this);

     s3 = new JButton("The Pina Colada Song");
     this.add(s3);
     s3.setBounds(FRAME_WIDTH/2-100, FRAME_HEIGHT- 100, 200, 50);
     s3.addActionListener(this);

     s4 = new JButton("Come and get your Love ");
     this.add(s4);
     s4.setBounds(FRAME_WIDTH/2-100, FRAME_HEIGHT- 250, 200, 50);
     s4.addActionListener(this);

     stop = new JButton("STOP");
     this.add(stop);
     stop.setBounds(FRAME_WIDTH/2 -55 ,FRAME_HEIGHT/2 +40, 100, 50);
     stop.addActionListener(this);


     exit = new JButton("Close");
     this.add(exit);
     exit.setBounds(FRAME_WIDTH/2 -55 ,FRAME_HEIGHT/2-400, 100, 50);
     exit.addActionListener(this);


 }      




public void actionPerformed(ActionEvent e) {


    Object src = e.getSource();

    if(src.equals(exit)) {
        System.exit(0);

    }else if(src.equals(s1)) {


        try {
            SimpleAudioPlayer sap = new SimpleAudioPlayer("src/wavs/Hooked.wav");
            sap.play();
        } catch (UnsupportedAudioFileException | IOException | LineUnavailableException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        ;



    }else if(src.equals(s2)) {



    }else if(src.equals(s3)) {


        try {
            SimpleAudioPlayer sap = new SimpleAudioPlayer("src/wavs/Escape.wav");
            sap.play();


        } catch (UnsupportedAudioFileException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (LineUnavailableException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }




    }else if(src.equals(s4)) {

    }else if(src.equals(stop)) {

    }


}

}

我的声音可以播放，但是当我播放新歌时，第一首歌曲会随着我输入的新歌曲而继续播放，并且stopClip方法不起作用。
