I was creating what I deemed to be a quite simple program that played a .wav file in Java, but the sound is not playing when the program is started. All of my imports seem to be good, and I am not too sure why it is not playing, and I am starting to wonder if it is a problem with where I placed my files. I have attached both my code, and a screenshot of the location of my files for this project here. Please tell me if more information is needed. Any help is appreciated.
package javaSounds;
import java.io.File;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public class JavaSounds {
public static void main(String[] args) {
File explosion = new File("explosion.wav");
PlaySound(explosion);
}
static void PlaySound(File Sound) {
try {
Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(Sound));
clip.start();
} catch (Exception e) {
}
}
}
The problem is not the addressing but that the program finishes and closes before the sound gets played.
The command clip.start() launches and plays the sound on a daemon thread. These threads, even while running concurrently, will not hold a Java program open. Since there is nothing else happening in the program, everything shuts down and nothing is heard.
A simple way to test this is to add the command Thread.sleep(..) after starting the clip. A more usual practice is to trigger the sound from a GUI, where the presence of the GUI keeps the java program alive for the duration of the clip.
If your sound doesn't play with the addition of a sleep pause, then we can look at the addressing. By the way, it's better to get your AudioInputStream from a URL than from a File. If you plan to jar your program and include audio resources as part of the jar, File will be unable to locate those internal resources.
I'm trying to play a sound when a button is clicked or when a new view is showing up. I wrote this method to play a sound:
void play_sound(String musicFile) {
AudioClip sound = new AudioClip(new File(musicFile).toURI().toString());
sound.play();
}
and this is how I call it:
String musicFile = "src/resources/sounds/applause.mp3";
play_sound(musicFile);
I have to mention that applause.mp3 is downloaded from the web and when I play a sound from web it works. But when I want to play a sound that is recorded (for example app.mp3), it doesn't work anymore. All these files are in the same folder(sounds).
Your file path should definitely start with a / to mark it as absolute (inside of the jar file).
Then, you should'nt use the File class to load resources from inside the jar file. Use
String path = getClass().getResource("/resources/sounds/applause.mp3")
AudioClip sound = new AudioClip(path);
instead.
Cheers
I'm using NetBeans and trying to make a Jbutton play this .wav file that I have located in the build/classes/shadow part of my project. I want the .Jar to build with the .wav file so I could download the .Jar file on another computer and press the button and the music will play. The music is not locating or starting I'm not sure which it is, also please be easy on the terminology I am very very new.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:File Clap = new File("sanic.WAV");
display.setText("cum on step it up!!!");
}
public static void startMusic() {
{
try{
URL url = Shadow.class.getClassLoader().getResource("sanic.wav");
play(); // NetBeans says it cannot find the symbol for play.
}catch(Exception e){
}
}
}
I'm not sure in what part of your code are you using your URL... But I'd suggest you to use AudioInputStream...
Regarding the problem finding the file... I had implemented something similar some time ago, while checking the code I have in my HDD, I found that this made it for me:
URL url = Shadow.class.getResource(myfile.wav);
But nowadays, I prefer working with this:
InputStream resourceAsStream = Shadow.class.getResourceAsStream(myfile.wav);
Hope it helps for what you need to do.
Regards and... happy coding :)
I have spent hours today looking up how to get some form of audio in eclipse and have had trouble every step of the way. Currently I have something that should work but I get an error:
Exception in thread "main" java.lang.IllegalArgumentException: expected file name as argument
at com.sun.javafx.css.parser.Css2Bin.main(Css2Bin.java:44)
I have basically copied this from someone who had it working. I would like to say that the FX lib is added where it should be. I know this isn't fancy but I was just trying the basics.
package b;
import java.io.File;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
public class test {
public static void main(String[] args){
String uriString = new File("C:\\Users\\Mike\\workspace\\b\\src\\hero.mp3").toURI().toString()
MediaPlayer player = new MediaPlayer( new Media(uriString));
player.play();
}}
I have also tried many different path names in case it was wrong with no luck, I also just tried to copy and paste the path name that i got in eclipse by going to properties ex: /b/src/hero.mp3. Help would be appreciated to get me out of this nightmare.
The files located outside the workspace should be included with file:// prefix. A simple example demonstrating the functionality is
public class Reproductor extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
Media media = new Media("file:///Movies/test.mp3"); //replace /Movies/test.mp3 with your file
MediaPlayer player = new MediaPlayer(media);
player.play();
}
}
If the file is into the resources/music this will work and the application will be portable,.mp3 inside the .jar:
Media media = null;
try {
media = new Media(getClass().getResource("/music/hero.mp3").toURI().toString());
} catch (URISyntaxException e) {
e.printStackTrace();
}
I suspect you have a issue with referencing embedded resources. An embedded resource is any file which is contained within the application context (ie. In this case, stored within the application Jar).
In order to obtain a reference to these resources, you need to use Class#getResource, which returns a URL, which you can then use to load the resource depending on your requirements, for example...
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
String path = Test.class.getResource("/Kalimba.mp3").toString();
Media media = new Media(path);
MediaPlayer mp = new MediaPlayer(media);
mp.play();
System.out.println("Playing...");
}
public static void main(String[] args) {
launch(args);
}
}
Now, I couldn't get it to work until I wrapped in a Application context...
JavaFX EMBED an MP3 into the jar (in the jar) with NetBeans
I programmed my very first JavaFX package in NetBeans, and then I wanted to add sound, an mp3 music file, embedded in the jar, inside the jar, so that I could email the jar to my friends and the music would play on their computers. Thank you StackOverflow for your help. Thanks especially to the member who said “put your music file IN THE JAR, getResourceAsStream() is the API you want to use.” He put me on the right track, although I ended up using getResource(). It works.
STEP 1: Firstly, I got the music to play when I hit run in NetBeans.
STEP 2: I wanted the music to loop (repeat). Eventually I got that right, thanks to the members of StackOverflow. Please see my source code.
STEP 3: Finally I got the mp3 to EMBED in the jar. Now, this is important. At first the music played on my computer, but the jar read it off my hard disc. When I changed the name of the mp3, then the jar crashed, it would not run, it could not find the mp3. I had to embed the mp3 into the jar, put it inside the jar (in the jar) otherwise it would not play on somebody else’s computer. That’s where getResource() did the trick.
STEP 4: Then I emailed my jar to friends. Some service providers don’t trust a jar, they sent the emails back to me, undelivered. Other service providers don’t have a problem and delivered the emails. So, what did I do? I changed the name of the *.jar to *.mp4 and the emails were delivered, I asked my friends to change it back from *.mp4 to *.jar. It worked.
Here is my source code. I’m sure it’s not perfect, but it works, thanks to StackOverflow.
/* Of course, one needs to import the following gizmo’s (and others): */
import javafx.util.Duration;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
/* I want to EMBED the music inside the jar (in the jar).
The secret seems to be getResource. The source code starts here,
to EMBED the sound (DollyParton.mp3) into the jar: */
//************************ begin the music ***********************
#Override public void start(Stage primaryStage) throws Exception {
init(primaryStage);
primaryStage.show();
play();
}
public static void main(String[] args) {
launch(args);
}
MediaPlayer musicplayer; {
/* Put your music file IN THE JAR, "getResourceAsStream()" is
the API you want to use. Put the DollyParton.mp3 into the Windows
folder src/rockymountain. NetBeans automatically copies the mp3
to the folder build/classes/rockymountain. */
Media mp3MusicFile = new Media(getClass().getResource("DollyParton.mp3").toExternalForm());
musicplayer = new MediaPlayer(mp3MusicFile);
musicplayer.setAutoPlay(true);
musicplayer.setVolume(0.9); // from 0 to 1
//***************** loop (repeat) the music ******************
musicplayer.setOnEndOfMedia(new Runnable() {
public void run() {
musicplayer.seek(Duration.ZERO);
}
});
//*************** end of loop (repeat) the music **************
}
//**************************** end of music *************************
I put the mp3 into the Windows folder src/rockymountain. Then NetBeans automatically copied the mp3 to the folder build/classes/rockymountain. NetBeans does not copy the mp3 to the folder /resources, a file that I created unnecessarily, because someone said so. The /resources folder is not needed, it remains empty.
Create a Java ARchive (jar) file using NetBeans as follows:
Right-click on the Project name
Select Properties
Click Packaging
Check Build JAR after Compiling
Check Compress JAR File
Click OK to accept changes
Right-click on the Project name
Select Clean and Build
The JAR file is built. To view it inside NetBeans:
Click the Files tab
Expand ProjectName >> dist (distribution). The jar file is inside the dist folder.
Try to add --add-modules=javafx.controls,javafx.media in your VM options.
I tried this three lines and it worked!
Media sound = new Media(new File("src/music/menu.mp3").toURI().toString());
MediaPlayer player = new MediaPlayer(sound);
player.play();
First you need to put the code in try and catch to catch any error, second you must
define the JFXPanel to define it to the media package and the tool kit ,so this is the code:
package test1;
import java.io.File;
import javafx.scene.media.Media;
import javax.swing.JOptionPane;
import javafx.scene.media.MediaPlayer;
import javafx.embed.swing.JFXPanel;
public static void main(String[] args) {
try {
JFXPanel j = new JFXPanel();
String uriString = new File(""C:\\Users\\Mike\\workspace\\b\\src\\hero.mp3"").toURI().toString();
MediaPlayer Player = new MediaPlayer(new Media(uriString));
Player.play();
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, ex);
}
}
and a good info for you can put only file name
inside the File() exp: String uri = new File("hero.mp3").toURI().toString();
I'm trying to make simple audio player with JavaFX Mediaplayer component. All local files are fine but i want also implement internet radio.
Code:
public static void main(String[] args) throws URISyntaxException {
new JFXPanel(); //init jfx library
String u = "http://91.121.164.186:8050";
Media m=null;
try {
m = new Media(u);
} catch (MalformedURLException e) {
e.printStackTrace();
}
MediaPlayer player = new MediaPlayer(m);
System.out.println("play");
player.play();
player.setVolume(new Double(1));
}
When I run it like this there is no errors but there is no audio. What's wrong ? What are other posibilities to play radio stream in Java ?
In your current example I can see two errors,
You are trying to run a JAVAFX component on a non-Javafx thread, which will result in error. Try running your program inside the start method. Please go through How to use JavaFX MediaPlayer correctly?
The URL you are trying to access must be a Media Compoenent
Try going through this extremely great example on Javafx Media
http://docs.oracle.com/javafx/2/media/EmbeddedMediaPlayer.zip
N.B. The example has lot more data than your require, but its a great example !
"http://91.121.164.186:8050" is a website, (HTML document), not a audio file. You need to download an audio file, something that the player knows what to do with.
