Hello,
While I know I can't load .wav files dynamically in Flash and play them, I did find a workaround solution. However, I can't quite figure out how to get started.

In my list of questions, here's the big one: How do I load a .wav file into a byteArray?

Once I get that far, I should be able to use popforge (http://code.google.com/p/popforge/) library to convert the byteArray into samples, and eventually a Sound object. Also, working in CS3 (not Flex), this page is handy for making it all work in CS3 in case you are curious: http://www.signar.se/blog/popforge-flash-workaround-fp-9/comment-page-1/#comment-42

I appreciate any help you could provide! Thank you much in advance.

OK this is easy.

There are essentially two ways I know of. One is URLLoader and the other is using FileReference.

FileReference allows the user to browse through explorer and select the file whereas URLLoader hardcodes the path, it can be changed but you should get what I mean.


I used frame code just for sample as it's easy,if you want I can convert it to a document class if you want.

If you need help with any of the code, just ask.

I divided the two code below in the code snippet.

~~~~~~URLLoader Method~~~~~~
 

var byteArray:ByteArray;
 

var loader:URLLoader = new URLLoader();

loader.dataFormat = URLLoaderDataFormat.BINARY;

loader.load(new URLRequest("test.wav"));

loader.addEventListener(Event.COMPLETE, completeHandler);
 

function completeHandler(evt:Event):void {

	byteArray = loader.data;	

}
 

~~~~~FileReference Method~~~~~
 

var byteArray:ByteArray;
 

var file:FileReference = new FileReference();

var fileFilter:FileFilter = new FileFilter("Wav Files (*.wav)", "*.wav");

file.browse([fileFilter]);

file.addEventListener(Event.SELECT, loadFile);

file.addEventListener(Event.COMPLETE, completeHandler);
 
 

function loadFile(evt:Event):void {

	file.load();

}
 

function completeHandler(evt:Event):void {	

	byteArray = file.data;

	trace(byteArray.length);

}
