java - 在java中同步音频

Question

我有一个用于暂停和播放的音频按钮。我为此功能使用了一个按钮，即当用户按下播放时播放声音，然后按钮文本变为暂停。我似乎无法让音频暂停(其余部分有效)

private JButton playBtn;
    private Boolean pauseStatus = false;

    public SoundClass() throws UnsupportedAudioFileException, IOException {
        setLayout(new BorderLayout());

        playBtn = new JButton("Play Audio");
        playBtn.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                try {

                    if(pauseStatus==false){
                    setPauseStatus(false);
                    play();}

                    if (getPlayStatus() == true) {
                        play();
                        playBtn.setText("Play Audio");
                        setPauseStatus(false);

                    } else {

                  playBtn.setText("Pause Audio");
                   setPauseStatus(true);
                    }

                } catch (LineUnavailableException ex) {
                    Logger.getLogger(SoundClass.class.getName()).log(Level.SEVERE, null, ex);
                }
            }

        });

        add(playBtn, BorderLayout.NORTH);
    }

    public void play() throws LineUnavailableException {

        try {
            File soundFile = new File("/Users/joebloggs/Desktop/Java/Ensoniq-SQ-2-Electric-Piano-C4.wav"); //you could also get the sound file with an URL
            AudioInputStream audioIn = AudioSystem.getAudioInputStream(soundFile);
            Clip clip = AudioSystem.getClip();
            clip.open(audioIn);
            clip.start();
        } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (LineUnavailableException e) {
            e.printStackTrace();
        }

    }



    public void setPauseStatus(boolean b) {
        this.pauseStatus = b;

    }

    public boolean getPlayStatus() {
        return this.pauseStatus;

    }

您可以获得帧位置，停止播放，当您想要继续播放时，将帧位置设置为您停止播放时的位置。

例如:

暂停

int pos = clip.getFramePosition();
clip.stop();

或

int pos = clip.getMicrosecondPosition();
clip.stop();

简历

clip.setFramePosition(pos);
clip.start();

或

clip.setMicrosecondPosition(pos);
clip.start();
