How to play clean audio loops and one-shot sounds in parallel in JavaFX 2.0? - javafx-2

Question

I'm trying to play background audio in a loop in a JavaFX 2.0 application using JavaFX SDK 2.0.1. I decided to use a MediaPlayer created by the following piece of code:
MediaPlayerBuilder
.create().media(BACKGROUND_MEDIA)
.cycleCount(MediaPlayer.INDEFINITE);
This basically works, but when a new cycle starts there is a tiny (latency?) gap between the end and the start of the audio. So it's not a working option for me since it's not playing a clean loop.
I decided to build a new MediaPlayer object and start playback everytime Media ends. This works fine so far. Additionally, I use a button playing a short AudioClip when clicked.
I discoverd that frequent and fast clicking this button leads to interrupts in the background audio. I created an example to reproduce this behaviour by inifinitely playing an AudioClip with volume 0 when the button is clicked once. The example is not self contained, since the required audio files are missing. It requires to place 2 audio files in the project's source directory:
click.wav (a really short click sound ~300ms)
background.wav (~5 seconds of audio)
How do I achieve playing a clean audio loop in background without these interrupts when other one-shot audio sounds are played? Is it just a performance issue?
Example:
package mediatest;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.media.AudioClip;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaPlayerBuilder;
import javafx.stage.Stage;
public class MediaTest extends Application {
private static final AudioClip CLICK_AUDIOCLIP = new AudioClip(MediaTest.class.getResource("/click.wav").toString());
private static final Media BACKGROUND_MEDIA = new Media(MediaTest.class.getResource("/background.wav").toString());
private MediaPlayerBuilder builder;
public static void main(String[] args) {
Application.launch(args);
}
#Override
public void start(Stage primaryStage) {
Group root = new Group();
Scene scene = new Scene(root, 300, 250);
this.builder = MediaPlayerBuilder
.create()
.media(BACKGROUND_MEDIA)
.onEndOfMedia(new Runnable() {
public void run() {
MediaPlayer player = MediaTest.this.builder.build();
player.play();
}
});
MediaPlayer player = this.builder.build();
player.play();
Button btn = new Button();
btn.setText("Repeat playing short audio clip");
btn.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
//Simulation of many button clicks
MediaTest.CLICK_AUDIOCLIP.setCycleCount(AudioClip.INDEFINITE);
MediaTest.CLICK_AUDIOCLIP.play(0);
}
});
root.getChildren().add(btn);
primaryStage.setScene(scene);
primaryStage.show();
}
}

Answer 1

have you looked into ExecutorService? You would then have a number of predefined threads like so:
ExecutorService service = Executors.newFixedThreadPool(4);
where 4 is the number of threads it makes.
It will improve performance because it uses already made threads rather than making a new one each time you want to run something.
You would create a Runnable and execute it with the service like so:
Runnable r = new Runnable() {
#Override
public void run() {
playSound();
}
};
service.execute(r);
Not only would this improve performance but it automatically assigns the job to a not-currently-busy thread in its thread pool.
Also look at this: Playing sound loops using javafx which I believe solves your small latency problem.
EDIT: damn sorry, I didn't know this post was that old. It was a top result in google.

Answer 2

Using another thread at
public void handle(ActionEvent event) {
Platform.runLater(new Runnable()
{
#Override
public void run()
{
//Simulation of many button clicks
MediaTest.CLICK_AUDIOCLIP.setCycleCount(AudioClip.INDEFINITE);
MediaTest.CLICK_AUDIOCLIP.play(0);
}
});
}
});
May solve the problem of the interruption
