R – Sound visualization in ActionScript 2.0

actionscript-2actionscript-3audioflashvisualization

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

Best Answer

A: AS2 cannot analyze the sound in real time. Your best bet is to run it through some software that can export the values to a file, load the file, and visualize the numbers somehow.

B: AS3 runs under AVM2 while AS1/2 run under AVM1. It is not possible to load an AVM2 file into AVM1. You could create an AS3 file that loads the AS2 file and gets the spectrum and visualizes it. Any audio going out (except microphone, with the current flash player) will be analyzed. Sending the numbers back to AS2 for whatever reason becomes hacky (using LocalConnection) and most likely will cause sync issues etc.

Not sure I get exactly how the application works so excuse me if I'm wrong. If the flex instance must load the AVM1 proxy wouldn't it be possible to inject a flash-var via the URL containing a generated ID for the LocalConnection to use ?

In addition to your comment, just added how to send variables to the AVM1 movie. This works fine locally at least (not tested on network):

AS3 - FP10:

loader = new Loader();

var request:URLRequest = new URLRequest("as2proxy.swf");
var variables:URLVariables = new URLVariables();
variables.id = "local_connection_id";
request.data = variables;

loader.load(request);

AS2 - FP7 (first frame on the timeline of "as2proxy.swf") :

trace(id); // (_root.id)

BTW, stumbled on the following class from Libspark : http://www.libspark.org/svn/as3/ForcibleLoader/src/org/libspark/utils/ForcibleLoader.as

R – How to receive the events from an ActionScript 1/2 swf in a flex swf

You'll need to use LocalConnection calls for the two swfs to communicate, even within a parent swf. Grant Skinner wrote SWFBridge which may be useful to you: http://www.gskinner.com/blog/archives/2007/07/swfbridge_easie.html.
