The following code is neither producing sound nor printing a stack trace. If I debug, stepping over clip.start()
will make sound play for a brief fraction of a second. Does anyone have an idea of what I'm doing wrong? Thanks.
import java.net.URL;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.DataLine;
public class Driver {
public static void main(String[] args) {
try {
URL url = new URL("http://api.voicerss.org/?KEY=b1a362bc35014e9c9dcd8d3536aac7ad&SRC=This%20is%20a%20test&HL=en-gb&C=WAV&F=48khz_16bit_stereo");
AudioInputStream sound = AudioSystem.getAudioInputStream(url);
DataLine.Info info = new DataLine.Info (Clip.class, sound.getFormat());
Clip clip = (Clip) AudioSystem.getLine(info);
clip.open(sound);
clip.start();
while(clip.isRunning());
} catch (Exception e) {
e.printStackTrace();
}
}
}
Also, changing while(clip.isRunning(());
to while(clip.isRunning()) System.out.println("running");
does not result in any output.
It's about thread issue.. when I tried to run it in Event Dispatch Thread, it runs fine..
you may learn about EDT from this discussion:
note: I hope others might found better solution for this though..
