i have some arbitrary signal data which i'd like to get a frequency analysis of. it's not audio data. is there a way to coerce AS3's computeSpectrum() call into doing this work for me ?
View 1 RepliesI am executing a computeSpectrum function every 1/10 of a second (the speed I should be sampling the sound frequency to obtain a data bit). However the computeSpectrum seems to be giving me the same output every two or three times I call it.
Take a look at the source code and check the Binary read. Notice the binary read is repeating numbers, and the lack of single '0' or '1' bits? There should be some single '0's and '1's in there! I even made arrays of all of the input to check if the uncompressed ByteArray data was repeating and sure enough, the samples were quite often IDENTICAL every 2 or 3 calls...
PS: The audio sample data [More audio samples available there] I'm using is Peceptive Development's 'How to talk to Tin Can' [More info on reading audio as data there]. The audio sample provided in the archive is 'Low speed', which means the data is being sent at 100 baud (100 baud / 1000 ms = 10 bits per second)
I'm used to using SoundMixer.computeSpectrum, but I need to get some data on-the-fly from the microphone (and I can't use the SoundMixer with the microphone).
I'm having trouble translating the FFT data (from this class) as shown in this excellent spectral analysis example to match the ByteArray output from computeSpectrum. My existing code is built to handle the data received from computeSpectrum (with FFT set to true).
I have an arbitrary number of files that I need to load in an AIR app.I want to iterate through an array of File object and create and launch Loaders for each one's File.url.When they are done (event COMPLETED or IOErrorEvent.IO_ERROR), I want to stuff their data somewhere. If they fail, I want to make an exception report. I cannot find any way to reference the File object from the event listener (certainly not the IO_ERROR)The best way would be to create individual event handlers for each Launcher that had the File information "hard-coded" into it. At the very least, I could use the function itself as an index to a Dictionary:
foo(fileToLoad : File) : void
{
var theCompletedHandler : Function =
{
[code]....
Can I use event.currentTaget and use the Loader instance as an index? Will that have any weird dependencies ?
I wrote something to capture sound from my microphone. I can visualise the sound data with SoundMixer.computeSpectrum.is there a way to mute the sound and still get sound data from SoundMixer.computeSpectrum?Now I have this:
sc=son.play();
var t:SoundTransform = new SoundTransform(0, 0);
sc.soundTransform = t;
but I do not get any data. if I pump up the volume, data comes through again(I need to mute it because it will echo otherwise).
Im new to placing external data into Flash. I just got CS3 and Im trying to use Flash to dynamically load XML data via a FlashVars call in the HTML.
The problem is I have followed the very straight forward AS2 Help files for using FlashVars and URL variables.I have placed the code directly from the Help file into the Html between
<noscript> <noscript>and i keep getting undefined.I have tried saving the file as flash 8 and i am publish flash 8.
I want to separate the data from the PHP call to Different CollectionArrays So that I can use the data for a bar-graph;
I created a static version of the bar-graph and separated the Collection array manually I don't want this done manually I need to do it dynamically. So what I am trying to understand is where to put the event-listener how to add to a collectionArray then once the collection array(s) are built. use that information to build the bar graphs...

is possible to draw a border around an arbitrary Shape (or Sprite) dynamically with ActionScript? From the IDE is really easy, just select the line color and click the Shape with the paint tool (S).How can we the same with Actionscript?
View 0 RepliesUsing the example found in the class documentation, you'll notice the bass frequencies are crammed on the low end too much, and the higher frequencies will sometimes register even in the bytearray.position = 0 float. Is this a problem with the design of the computeSpectrum class? Because I can take the same file, put it in another spectrum analyzer and see the bass and treble spread more evenly.[URL]
View 4 RepliesI'm building a media player with a sound visualizer using computeSpectrum(). When I adjust the volume, there is no longer any data for the visualizer. Does anyone know a way to adjust the volume of audio, but still access audio data using computeSpectrum() as if the sound were still audible?
View 3 RepliesJust wondering how often Flash (as3) will allow me to computeSpectrum? I am currently attempting to computeSpectrum 100 times per second, but I am finding that the data repeats every few times.

View 3 RepliesI'm trying to figure out how to tile a rectangle (the stage) with an arbitrary number of rectangles. Simple tiling where all the tiles are the same size and simply stacked in a grid.I'm doing this with a resizable layout and a number of tiles that is arbitrary and will change over time.
Given a more or less 4:3 or 16:9 monitor I would like a solution that tends toward minimizing the perimeter of the tile and being similar in aspect ratio to the screen. I realize that if I have a prime number of tiles that I won't be able to make a nice grid, but other than that it seems there should be some way to do this.Lets say I have 231 tiles I need to arrange. The factors are 1, 3, 7, 11, 21, 33, 77 and 231.If the screen is really, really wide 1 x 231. Wide but not not as crazy wide as before 3 x 77. And most likely 11 x 21 is what I would need.So is there an easy way to do this on the fly? Is there a pre-calculated way to make it easy?

View 2 RepliesSay I've got a utility class in which I would like to access the stage (in order to get the frameRate).

Is there any way to get ahold of the stage without it being passed in? All I need is the frameRate!
Below is code that populates a menu. Everything seems to work great, with no errors thrown, except for one crucial part. My megaPages array has the values ["HOME","BABIES","BRIDALS","MISC","WEDDINGS","ABOUT"], but the actual text that displays on screen (which is produced by megaPages) is like this:
As you can see, some of the text is arbitrarily being truncated. I've traced the text strings as they get passed through the various functions at various stages of the menu-build, and they are always right, but somehow when each DisplayObject make it on screen, letters get ommitted (notice though that 'HOME' abd 'ABOUT' are fine). I don't even know where to start with this problem.

I have a floor plan of a building in PDF that I want to visualize as a map, using tools like MapBox, FusionMaps, or AmMap. I am willing to redraw the floor plan if needed. What format should the map data be in? What kind of tool can I use to create that data?
View 3 RepliesI have several custom functions that I import as .as files, but I frequently have to modify them to suit projects, which makes standardization and version tracking harder.Is there a way to pass arbitrary expressions to a function when it's called? For example, if I write the function,
Code:
function foo(){
for(i=1; i<=1; i++){
trace(i);
}
}
would there be some way to attach an additional expression after the trace function during the function call? As in,
Code:
foo(do_stuff_here);
where the function would act as if it had said,
Code:
function foo(){
for(i=1; i<=1; i++){
trace(i);
[code]....
but without modifying the original function?I realize I could add an expression to the original function within a conditional, and toggle it via an argument within the call, but since I don't know what I'll add next, or whether I'll need it next time, this would become impractical quickly.

Since there's (obviously) only one instance of SoundMixer in any given file, is it not possible to run computeSpectrum discreetly on different soundfiles loaded into an application? Basically I want to visualise each sound differently. Anyone come across any workarounds?
View 4 RepliesFor the past couple of weeks I've been wracking my brains over SoundMixer.computeSpectrum(), arguably the coolest method in ActionScript 3. It's the one that spits out the last 256 (or so) audio samples that hit the speakers, with the option of viewing that data in the time domain (waveform) or the frequency domain (Fourier transform). It's great for visualizing music, but its major drawback is that it only operates on global, playing audio, which means you cannot visualize different channels or preprocess the visualization.
Sound.extract(), a new method in Flash Player 10, gives you a Sound object's entire waveform at any time you want; I've managed to line up the waveform in Sound.extract() perfectly with the waveform in SoundMixer.computeSpectrum(), so they are literally neck-in-neck. In this SWF I'm drawing two lines- a blue line, which uses data from SoundMixer.computeSpectrum(), and a red line, which uses data from

I'm trying to do some beat detection on a sound, but I want other sounds playing at the same time, and I don't want those to be included in the beat detection. Is there anything like SoundMixer.computeSpectrum for individual Sound or SoundChannel instances ?
View 2 RepliesI'd like to convert an arbitrary string (or for easier process a string hash) to a float number between 0 and 1. The purpose is to create a function that returns a color code for a given string so the user always sees that entity in the same color that is generated from its name.OP included this code in comments (included here for readability):
var hashed:String = MD5.hash(input); // creates a 32 long hexa
const max:Number = Number("0xffffffffffffffffffffffffffffffff");
var hashedHexa:Number = Number("0x" + hashed);

In ActionScript 1 and 2, if you compare undefined, null or NaN with an arbitrary number using >= or <= operator, the result is always true. Test code:
var x, n, range = 1000;
for (var i = 0; i < 3; ++i) {
switch (i) {
case 0:
x = undefined;

Furthermore, isNaN(null) return true. These are contrary to JavaScript and may not conform with ECMA standard.
I want to be able to take a general sine wave y=Math.sin(x) and rotate it around some other angle, so instead of going strictly left-to-right, I'd like to go from, say, the top left corner toward the "center," or from the bottom right to the center, or any other arbitrary angle. Like this: I want to be able to use that wave as a "path" for enemies in a game, but I cannot seem to wrap my head around it. I've tried matrix transformations, but I was missing something there, too, because the origin was wrong.

View 4 RepliesI have a Flex3 app I wrote and I'm streaming audio over RTMP from a Red5 server. I'd love to be able to use SoundMixer.computeSpectrum(), but the spectrum data is all zeros. In one location, Adobe writes that SoundMixer.computeSpectrum() does not work with RTMP data:
"For media loaded from RTMP sources, you cannot use the BitmapData.draw() and SoundMixer.computeSpectrum() methods to extract run-time graphics and sound data." [URL] Clear enough. Except, there's the actual documentation for computeSpectrum(): "In addition, this method cannot be used to extract data from RTMP streams, even when it is called by content that reside in the same domain as the RTMP server. [...] This method is supported over RTMP in Flash Player 9.0.115.0 and later and in Adobe AIR."
