Java :: Building Music Visualizer Using Fractal Patterns
Jan 30, 2011
I am interested in building a music visualiser using fractal patterns for my final year project. I have googled quite a lot on it and I know a bit about fractals, however I was wondering what software would be used to 'animate' the graphics. I know Java has a drawing API (AWT and Swing) - but probably no the best for the animation factor - on the other hand there is also Flash that has new capabilities within as3 to produce such an effect but if this app was to traverse into mobile development, Flash wouldn't be a great choice.

I'm creating a music player to be on my website and so far I have it set up as such: The player is contained in a movieclip with a 'song progress bar', a pause and a play button.The songs are played by clicking the song title in a list in the main stage (not contained in the player movie clip), which sends the music player to the frame in which the song starts.
My audio is set as event audio so that the play and pause buttons can be coded as play(); and stop(): respectively which will stop the main player movie clip thus yeilding the progress bar from moving further and the song from playing.
This works just fine, except for the following:
- When I select event as my audio type the quality reduces dramatically Having the audio files in my library and not obtained from some outside source (i.e on my website's server) causes the .fla file to be much larger as well as the .swf Being as my project is at 24 FPS and each song is represented in as many frames as it takesto play the song out, my music player at present has only 3 songs 'in it', and my frames in the movie clip are approaching 20,000 (this is VERY tedious to work with)
I'm sure there is a more efficient way of doing things, but my knowledge is limited. I'd imagine I can do something along the lines of loading .mp3's off of my website into the frame and the play pause buttons will enact more elaborate scripts that not only stop the progress bar but also stop the music from playing temporarily, or something like this. But I have no idea how to implement it

Most of the desktop application development I do is in Swing, and I'm curious to hear people's thoughts on using JavaFX and/or Adobe Flex for building desktop applications. Have you had success building desktop apps with these? Or would you stick with Swing for now and use tools to help make Swing development more productive?

I'm building a multiplayer card game using Flex on the client side and Java on the server side and I wanted to know if I must sockets and the accept method in order to connect users to the server for in order for them to join a game room or create one or to chat.In the past I've learned how to build a game server which both sides are JAVA and connection was in sockets but now days the client side will be in FLEX which has few ways to connect to a Java server (XML,SOAP,BLAZEDS(AMF)) and I find it hard to understand how to write the Java server in order to do all the features of a game server,especially managing the rooms and sending data back to the users.
In the sockets way, when a user was connecting to the server and he had opened a room, this room was opened on a thread and who ever was joined that room then he was connected to the same thread and sending the messages to the right place was easy, so the problem is understanding how to do the same using SOAP or BLAZEDS.

I have a question on how to combine 2 OOP design patterns. First off, I created a MVC pattern that loads XML into the as3 classes. Now, I want to add another OOP design pattern which is the OBSERVER pattern. How would I call that in the MVC pattern?
To be more clear about this, I created a MVC pattern design of a widget that loads the data from the xml file. I want to input a graph bar observer pattern to the widget. How would i do that?

It works great but only if run it from my desktop. If I change the url to an http source and then upload the swf/html it will load the song but the effect seems choppy since it has to preload the entire song first.

I need to create a basic bar chart distribution in ActionScript 2.0 based on sound output. I realize that ActionScript 3.0 has a very nice sound visualizer class SoundMixer.ComputeSpectrum but the limitations of my project require me to use ActionScript 2.0. Im wondering if you know of
A. Any third party libraries that I can use or purchase to create basic visualization effects based on sound output in AS2
B. Whether it is possible to create the sound visualizer in ActionScript 3.0 and somehow import/embed the AS3 file/swf in the AS2 file but allow the AS3 file to read from the AS2 sound

I had experiences using Mate and Parsley. But for now, I'm using none.For instance, I'm using observer and singleton patterns like following.
RegisterView.mxml implements IRegisterAction interface
function onBtnRegisterClick(){
var action:RegisterAction = new RegisterAction();[code].......
This is my interface IRegisterAction.as
function registerCallback(customer:Customer ):void;
My question is "What additional benefits I will get, if I use a particular framework ?".

How to make a "frame rate visualizer" in flash 8. Because some of my animations have slow frame rates if I use some bitmap or png images, or some big vector objects. So, it is possible to make a real time "frame rate" visualizer for my flash animations? Just like the frame rate viewer of some games.

I created my own custom audio visualizer in as3 a while back and it all worked perfectly fine, but since the update of Chrome in the past week it has stopped working.I think it could be the use of SoundMixer, compute Spectrum or ByteArray that is causing Chrome to block it. Most likely due to security reasons.Has anyone else had a problem viewing as3 audio visualizers in Chrome. I've uploaded my visualizer, so can you try and see if it works URL.

I develop with Actionscript and was glad to see that AIR 2.0 was going to give access to mic input data. I planned to use this to create a visualizer set to the tempo of the incoming live audio. After doing a few days of google research it seems unlikely that it will be possible to analyze the data of the mic input in Flash/AIR. If anyone has ideas on how I can achieve this in AIR please let me know. (I'm open to workarounds.)Run on OSX Two windows - one that can go fullscreen while the other(controller GUI) stays put Able to access live mic input data I've done reading on FFT and understand what needs to be done on the sound side so no need to help with that.

I'm working on an animation where I have my "dog" fighting the evil vacuum cleaner. I got most of it to work the way I want it to.
1) I have movie clips entitled pepper_mc (where my dog is supposed to be walking), swirl (where a swirly-type symbol is supposed to spin over the dead vacuum's head), and vacuum_mc (where the evil vacuum is supposed to have a swinging arm (called vacuumarm_mc) that I created using the bone tool). When I add them to the stage and test them, the animations within the movie clips don't happen.
2) I have background music that I'd like to stop playing at the end of the animation, but I'm not sure how to do that. (using the stop(); actionscript doesn't help).Where am I going wrong? I'm using Flash Pro CS5.
Here's the file --> Pepper and the Vacuum of DOOM!

When the movies performs the getURL action, I want the music to continue playing, but the getURL function seems to stop the music at frame 152 (where the getURL action is placed), when I wanted the music to continue to frame 257 (the end of the movie). I hope I've explained this clearly

I am trying to create a music animator. It will have bars that move up and down do the beat of the music. This is like windows media player where the music animations play. I want it to be verticle bars, where some are in sync with like the base and others are in sync with the tempo. Does anyone know of a tutorial for this? I am trying to emplement it within my website so that whatever music I am playing will auto control the bars and sync.

I downloaded a flash template and have modified it to suit our company but there is something that I can't do. When the file loads in the browser, music immediately plays and loops until you click a button to stop the music. On our video page, we have video
that we need to play that has sound in it. How do I get the background music to stop when my video plays without having to go up and stop the music manually. The videos are loaded via an external XML document and there are no buttons in the FLA file to link code to. the website is [URL]

I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch.
For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely?
I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

I am a .NET Developer, but the question I am having is not related to .NETPlease keep this in mind even if my question sounds very trivial.This is my question:We have an swf in the browser, which communicates with a java extensionIts done using Smartfox Server(Used for MMO apllications)From the swf we are grabbing a portion of the screen as "Byte Array" in action script(3).And in Java, we are calling a function that converts the ByteArray to Image and then saves it.ur Java developer is encountering the errorSo basically, what I would like to know is this:How to accept the object type Byte Array from ActionScript in Java?Whats Java object type that is mapped to Byte Array in ActionScript?The conversion part is easy, I dare say. code in the ActionScript Section
public function savePhoto(uName:String, ba:ByteArray, descr:String):void{
var obj:Object = {};
obj.arr = ba;

I have a client-server multigame suite for PC ("kind of" cross-platform using cygwin), which is developed in Java(game menus and database management), C++ (server side), and adobe Flash (game graphics & interaction).
I have never tried to develop for android, so i have no experience.I am thinking of migrating this suite to google TV. So i would like someone with android experience to give a clue on the following :
1) Is it going to be easy to migrate the Java application to an Android application?
2) What kind of Flash support does Android have? Can it load directly swf applications? Does it have to load swf's through browser?
3) Can i find any kind of performance indexes for google TV hardware?
