Flash :: Translate FFT Data To Match ComputeSpectrum FFT Output
May 30, 2011
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).

The type count is correct but the information for the project is wrong.

I 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 stuck on this tutorial trying to learn how arrays functions. My task is to declare a variable, write an array, loop through the array and output the match in a textfield already created on stage. This code does that, but it gives me the match in number, instead of writing the name I get the number from the array, 2. How can I get the textfield to display the name Stian?
var bestevenn:String = 'Stian'
var mineVenner:Array= new Array();mineVenner[0]='Janne';mineVenner[1]='Liv';mineVenner[2]='Stian';mineVenner[3]='Henri

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 ?

Is there an easy way to output flash data into a word document or into a text file without using API scripts,PHP and all that kind of stuff? Because it's fairly over my head. And If there is a way possible - will it interfere with security settings on someones computer?

how to show output data in a text area. I'm making a logger of variables being sent from a game. I notice the output records all the data. But, when I make it into standalone, there isn't a output. How do you show the data in from the output into a text area on the layer.

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).

It seems there are lots of topics close to this, but none with answers. I have attempted to complete the Dinner Menu sample example in Flash 8. I finally got ti to work but the columns do not match the order of the items in the XML document. I cannot find an answer to this problem anywhere on the internet so far.

im using flash professional cs5.5 Here's my issue: I'm trying to translate my flash site with a .txt (loadvariable)
Here's my code so far:
It loads automatically the english at start so..
Code: Select allloadVariables("english.txt", "_level0");
and then, on button160 I have this
Code: Select allon (release)
{
loadVariables("french.txt", "_level0");
}
So I can only translate it one time... then I cannot revert back. How do I do it ?
I tried doing:
Code: Select allon (release)
{
if (var == "english.txt")
{

I 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."

I'm developing using Actionscript 3.0 for Flash Player 10.3.I'm using computeSpectrum() on a loaded .mp3. Running *Event.ENTER_FRAME* to get snapshots of each sample in an byteArray.The ByteArray contains 512 values (256 for each channel). These values are FFT Spectrum, ranging from 0 to 1.I can't use the peak frequency for each of the samples (as I found found out!) because the highest value is not necessarily the fundamental frequency. As a result I'm getting lots of random values all over the place.Of course I'm getting some correct too, but that's not enough.

I am trying to load an external XML file and then output select pieces of data (location data) based on mouseover events on different objects (images of provinces). Something is wrong with my attempt to put data from the XML into the text objects I created. I think it is finding the file because when I remove the file, it balks, and when the file is present, it stops balking. But it keeps saying "Access of undefined property" or other things along the lines of "This thing is empty". My guess is that the syntax is wrong in the area below which I marked with an "ERROR HERE" comment.[code]...

I need a very special component written in ActionScript 3. It is a rectangle filled with a bitmap. The bitmap is loaded from an external URL based on some programmed rules. The textured rectangle is then animated using Flash CS. Animation is performed using rotate/translate/scale/skew tools. How to create such a component and add it to Flash CS library?

Whenever I output the xml data, it still brings out the xml tags but on the second row it shows the elements.
//First Row Load
<item>images/1.jpg</item>
<item>images/2.jpg</item>
<item>images/3.jpg</item>
<item>images/4.jpg</item>
<item>images/5.jpg</item>
<item>images/6.jpg</item>
//Second Row Load
images/11.jpg
so on and so forth....
The AS I used is this:
//Loading of Images
if(rCount > 0 && index < rCount) {
var i = index;
index++;
var adThumb = qAds[i].*;
trace(adThumb);
I've tried using the "toXMLString()" and the "toString()" but still the same thing continues to output.

I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.

Using 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]

I'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?

I need to translate this AS2 code into AS3 ASAP! how to translate a few lines from AS2 to AS3 [URL]I was supposed to make a flash 9.0 cs3 menu with buttons that stay down until another button is clicked.I've found an example of this on the net, one that is perfect in every way for what I need to have done.However, as always, there's a catch. The code on that site is written in AS2, which doesn't work for me because I'm using some functions which are incompatible with it (I suppose they're AS3 supported only, e.g. loaderComplete)

am trying to make a mp3 player by using actionscript3.In this , am trying a upload a mp3 file and play that particular file. Am also using the computespectrum() to display the graphics.Now the problem am facing is with the computespectrum . Randomly , the computespectrum is failing for the same file and is throwing error.The error is as follows [code]Am actually uploading the file into a folder named "mp3files". The "mp3files" folder and the swf are lying in the same domain.
