I am planning to develop an application that does the following:

1) Receiving an audio streaming from a shoutcast server
2) Decode and push it throught producer to a shared buffer
3) Share audio data to as many consumers are interested to this feed.

What is the best practive for doing this? I tried several things without success.

Consumer / Producer Multi Threading Scenario

Jul 9, 2014

Just some questions regarding a Consumer producer program I am not understanding. Here are the two classes Below and my questions are :

1. In the main method for NamedConsumer, we created an instance of the class and call it "consumer" and we start it. Then we create another instance and we give its reference to the same variable. Doesn't this in turn destroy the original reference of the first instance we created which was started? Could we have done

NamedConsumer consumer1 = new NamedConsumer( "One", producer );
new Thread( consumer1 ).start();
NamedConsumer consumer2 = new NamedConsumer( "Two", producer );
new Thread( consumer2 ).start();

2. we called start on two difference instances of the NameConsumer class. Doesn't the "run" method need to be synchronized since two threads are hitting it?

Producer.Java

Java Code: public class Producer implements Runnable
{
static final int MAXQUEUE = 5;
private List<String> messages = new ArrayList<String>();

public void run() {
while ( true ) {
putMessage();
try {
Thread.sleep( 1000 );

Program Which Compares Audio File With Real Time Captured Audio

Nov 23, 2014

I wanted to know some hints on where to begin if I wanted to create a program which compares an audio file with real time captured audio. I found this website "[URL]...", but I think this would not do the job, so what are the basics of audio in java and how to compare audio files and see if they are compatible.

Managing Audio Files In Java

Apr 18, 2014

I'm doing a little game in Java and I would like to insert a background music managed by a JButton. When the button is pressed, the music starts and then, to stop it, the button is pressed again. If you don't press the button to stop the music remains in the loop until the player plays.

Design Patterns And Java Algorithms

Nov 22, 2014

I've looked over the concepts of Java programming, tested them in code and i understand most of them. I have a problem when i need to make harder programs , this might be because i dont know design patterns and algorithms.I'm curious what a entry level programmer needs to know to get a job in the field. Right now i was thinking i need to know:

1. The way all big concepts work and most of the keywords.

2. Design patterns.

3. Algorithms.

what i actually need to know for an entry level job and can you tell me which design patterns and algorithms are a must know for that first job. Considering i might have financial problems in the near future this is not a theoretical question, i really need to know what i need to learn in the next 2-3 months to get an entry level job down.

How To Make A Flat GUI Design With Java Swing

Apr 26, 2014

Here is an example of a GUI. Is it possible to make this kind of a thing using Java Swing? Is it possible to have a picture on the entire background of the JFrame, and then other Swing components like buttons, labels etc. sitting on it?Is it possible to have action listeners behind pictures? In other words, they will behave like buttons: the user clicks on them and they do something.

Transferring Coordinates From Design Program To Array In Java?

Mar 6, 2015

The idea I'd like to present, concerns the correction of "designer" drawings - those done by the design consultants - against "site/construction" drawings - them being used on site by the workers to build the project itself.

This is normally a laborious process, involving being sat at a desk with two large folders, checking each detail and measurement against the design drawing.What I'd like to present is an idea, where the co-ordinates of the design or "mother" drawing, are transferred into a usable Java program, and they could be then used to ensure correct dimensions have been applied by the the sub-contractors in their "construction" drawings.Like I said, this can normally be a process of days for a site engineer to check - process known as "QA, quality assurance".

Basically, I just need to make a presentation of having a genuine interest in Software Design and Development. It could be applied in a range of areas in terms of construction site application - checking drawings, writing up work orders, dig orders etc - but the principle of having the co-ordinates of the mother or "design" drawing scanned into an array in Java as a means to output those site drawings/orders etc, applies to each potential application.

So - in short - and not looking for crystal clear detail, just general pointers - what programs or methods could transfer a plethora of co-ordinates from a design program like Auto-Cad, to a Java program, where I assume I would then be using a program containing a complex series of loops to ensure the correctness of the derived "construction" drawings; derived from the "mother" or designer drawings, that is.

Disabling Audio With JButton

Oct 11, 2014

I am having right now is that I don't know how to stop my music from playing? I am making a Connect 4 game with some audio to make it intuitive. Below is my code. This is my Music method.

public static void Music() {
try {
File music = new File("C:\Users\Ken\workspace\Assignment1\src\Mario1.wav");
AudioInputStream audioIn = AudioSystem.getAudioInputStream(music);
Clip clip = AudioSystem.getClip();
clip.open(audioIn);

[Code] ....

I called this method into a JButton i implemented into my main GUI.

if (e.getSource() == SoundOn){
Music();}
if (e.getSource() == SoundOff){
//What do I put here?
}

There is the method and my JButton.

Audio-system Can't Find Any Mixers

May 13, 2014

I've moved working code over to a different computer, a 32 bit Dell PC running Win7 under Netbeans and Java 8. I can't get it to play or synthesize any sounds because it can't get any Mixers. I tried adding the standard provider entries to the sound.properties file (they aren't needed in my other computer, but I had to try), and it made no difference. I've tracked down the problem farther by getting the source code for these classes and stepping through.

The system seems to have the Mixer providers, but in java.util.ServiceLoader.LazyIterator$nextService() it is looping through a set of javax.sound.sampled.spi.MixerProviders and it hits the following error:

try {
S p = service.cast(c.newInstance());
providers.put(cn, p);
return p;
} catch (Throwable x) {
fail(service,
"Provider " + cn + " could not be instantiated",
x);
}

why this is happening?

Streaming Audio Files Over Web Using JMF Plugin

Feb 18, 2015

I've been experiencing problems with the JMF extension when used in an Applet on the web. The program has worked fine previously but not returns the following error...

PackageManager: error reading registry
javax.media.NoPlayerException: Cannot find a Player for : [filename]
at javax.media.Manager.createPlayerForContent(Manager .java:1412)
at javax.media.Manager.createPlayer(Manager.java:417)

[Code] .....

However the program works fine in Eclipse with no errors. I have tried reinstalling the JMF package and setting the CLASSPATH and JMFHOME but it still does not work. I am using the jmf-2_1_1e-alljava version. I have also tried putting the player code in an AccessController.doPrivileged() block but this still does not seem to work.

My code for the player is as follows....

private void play(final String track) {
Thread dispatch = new Thread() {
public void run() {
try {
if(player!=null)
player.close();

[Code] .....

Android Audio Decoding For Morse Code And PSK31

Jan 6, 2014

I have some software I need to write. I am planning to write two apps for Android, one of which will send and receive Morse code, and the other to send and receive PSK31 data.

Programming is not my strong point, and I am currently struggling on how to do this. I have researched the software, and I am having a hard time finding out how to decode the audio streams on Android. I have also had difficulty finding examples and source code as what I have found is mostly written in C/C++, whereas I need examples in Java.

I cannot program at all except html and css but I am willing to do and learn whatever it takes to make this work. I don't know where to start from or what language to use. The structure of the program is to type an english word and then it must give out a translation of my local language and vice versa and I would like to add audio to the words.
