public class customsize extends jpanel implements actionlistener {      jbutton playbutton = new jbutton(" >> play <<");     jbutton stopbutton = new jbutton(" >> stop <<");     jbutton pausebutton = new jbutton(" >> pause <<");      public customsize(){          setlayout(null);          playbutton.setbounds(12, 173, 116, 40);         add(playbutton);          playbutton.addactionlistener(this);         pausebutton.addactionlistener(this);         stopbutton.addactionlistener(this);          stopbutton.setbounds(140, 173, 117, 40);         add(stopbutton);          pausebutton.setbounds(269, 173, 140, 40);         add(pausebutton);      }      public void actionperformed(actionevent e){          if (e.getsource().equals(playbutton)) {              try {                 string soundname = "gangnam.wav";                     audioinputstream audioinputstream = audiosystem.getaudioinputstream(new file(soundname).getabsolutefile());                 system.out.println(audioinputstream);                 system.out.println(new file (soundname).getabsolutepath());                 clip clip = audiosystem.getclip();                 clip.open(audioinputstream);                 clip.start();             } catch (exception e1) {                 system.out.println("error.");             }          }         if (e.getsource().equals(stopbutton)) {             system.out.println("stop music.");         }         if (e.getsource().equals(pausebutton)) {             system.out.println("pause music.");         }      } } 

my first step in trying solve manually inspect properties of wav file itself. in windows, can right-click , select properties. then, there second tab has things bit rate , fps.

java can support 44100 fps, , 16-bit encoding. there daws now, though, produce wav files @ 48000 or 96000 fps, or @ 24-bit or 32-bit encoding. java not support these currently, afaik.

if have such file, can modify acceptable format (stereo, 16-bit, 44100fps) program audacity, free download. make sure home site. first time downloaded it, popuppalooza several hours until able rid of crapware came with. home site download (see wikipedia link) should fine.
