Java Sound Example

자바에서 사운드를 출력하는 간단한 예 (Java Sound Play Example)

gameover_wav.file

사운드 파일의 절대경로를 사용하는 경우, (Loading sound file from project outside)

호출 예) playSound( "d:/test/gameover.wav" )

private void jButtonPlaySoundActionPerformed(java.awt.event.ActionEvent evt) {                                                 

        playSound("d:/test/gameover.wav");

 }

public void playSound(String filename) { // d:/test/gameover.wav

        try {

            File soundFile = new File(filename);

            final Clip clip = AudioSystem.getClip();

            clip.addLineListener(new LineListener()

            {

                @Override

                public void update(LineEvent event)

                {

                    //CLOSE, OPEN, START, STOP

                    if (event.getType() == LineEvent.Type.STOP)

                        clip.close();

                }

            });

            clip.open(AudioSystem.getAudioInputStream(soundFile));

            clip.start();

        }

        catch (Exception e) {

            e.printStackTrace();

        }

    }

프로젝트 내에 사운드 파일이 포함되어 있는 경우 (Loading sond file from project inside)

호출 예) playSound( "gameover.wav" )

private void jButtonPlaySoundActionPerformed(java.awt.event.ActionEvent evt) {                                                 

        playSound("gameover.wav");

} 

   

public void playSound(String filename){

        try {

            URL url = getClass().getResource(filename);

            File file = new File(url.getPath());

            final Clip clip = AudioSystem.getClip();

            clip.addLineListener(new LineListener()

            {

                @Override

                public void update(LineEvent event)

                {

                    //CLOSE, OPEN, START, STOP

                    if (event.getType() == LineEvent.Type.STOP)

                        clip.close();

                }

            });

            clip.open(AudioSystem.getAudioInputStream(file));

            clip.start();

        }

        catch (Exception e) {

            e.printStackTrace();

        }

    }
