ActionScript 3.0 :: Converting Sound To Info (Numbers To Draw Waves)
May 20, 2009
I'm working a project for school in which I'm using the sound spectrum. Only problem is, I only know Action Script 2, which does not use it. I'm currently using this code to create sound waves and it works fine.
var url:String = "[URL]";
var request:URLRequest = new URLRequest(url);
var s:Sound = new Sound();
s.addEventListener(Event.COMPLETE, completeHandler);
s.load(request);
var song:SoundChannel = s.play();
[Code] .....
How to turn the sound into numbers (which are then usually used to draw waves).
I'm doing the finishing touches on my games. I want to keep track of and display the level (waveCount) and display it in a dynamic text box. However, AS isn't allowing me to convert the number into a string.

private var waveCount:Number = new Number(); private var waveOutput:String = new String (waveCount); private var waveWord:Sprite = new WaveWord();
I am currently trying to make a financial calculator that will calculate loan payments. However, I am having trouble converting the final product into a currency format.
I have seen that tutorial on Flashkit, but it has to be one of the hardest-to-read tutorials I have ever seen. Has anyone tried this, and if so, do they know a good way to handle this problem?
if the title of this post is misleading.I have a slider that outputs a number from 0 to 10 which is backwards from what i need. so when its 0 i need it to be 10. when its 1 i need it to be 9. when its 8,2. ect is there a function in as3 for converting these numbers?

I get this out put (each row is a different element) and I don't know how to convert it in to a readable value.
it should be number with 9-10 digits. from what I have seen in other sites regarding this specific data (this is the value of the tempo in a midi file) - it looks something like this: "tempo is 06 96 27 (in hexa format)"
these values are ByteArray type. how do I convert them to the readable numbers (or perhaps they contain text)?
Or... how do you XOR doubles without getting integer results? I am using Actionscript 3.0 and found the following:
var a:Number = 3.000000004; var b:Number = 29.999999999; trace ("a: " + a); //3.000000004[code]..........
Clearly, the XOR operation is converting my Numbers into ints. I am a bit surprised by this and don't exactly understand the reason behind it. But I do know that other bitwise operations will also change Number into int, so I am not that surprised.Be that as it may, is there a way to XOR doubles (aka Numbers) without having them get truncated to integers?I used the above XOR originally for performance optimization (these number switches are executed millions of times in an array).I assumed if I skipped the temporary variable, I would see a speed increase.Alas, if the Number data gets changed to int, it is all for naught.
public static function reversePairs(values:Vector.<Number>):void { //1, 2, 3, 4, 5, 6 -> 5, 6, 3, 4, 1, 2 var l:int = values.length;[code].........
does anyone know of a script that will take up to 500 words per conversion, or does anyone know a application that will be able to do this? unlimited amount of words would even be better.
What i want to do is to allow a user to input a time of when the alarm should sound. However, when i press like "2" or any number i get "22" instead of just "2".Also, is there a way to stop people from entering letters along with this piece of code?[code]
In the order listed above, I get the following trace when I export via Flash CS3 (9.0) on my PPC mac: number
boolean true true
[code]....
The same exact FLA file, unmodified, gives the following trace output on 2 different intel macs (one mac pro, one imac) using Flash CS3 (9.0).
number boolean false false
[code]....
have a clue why this is giving falses for statements such as "(Number(435/100)==4.35))", "(435/100==4.35)" or "(Number(input_txt.text)==4.35000)" but ISN'T giving a false for (Number(input_txt.text)==(435/100)) (NOTE: input_txt.text is an input field which contains the string 4.35) I'm expecting the latter since they're generally intel chipsets too??
Note: once i compile the code on my PPC mac, intel macs that run the SWF (but don't recompile the FLA) do return the correct booleans that match the PPC output.
I created an mp3 player but i have problems in getting info from XML file (song duration)
[Code]....
I'm new to the action script and problems about creating functions after preload() function i call for firstsong(). I have firstsong(), prevsong() and nexsong() functions and timebar() function that is called in each firstsong(), prevsong() and nexsong() functions. In problems about streaming audio this can't work for me and i come up with an idea that to add each songs time as seconds on XML.
im going through ASDG, page by page, and learning everything from scratch. he's explaining datatypes, i.e. strings, numbers, booleans, arrays, etc...i get that. then he goes into explaining how to convert datatypes from numbers to strings using "toString" , and then strings to numbers using "Number()"...and then later, strings to booleans and stuff. My question is this. where someone would want to turn a number into a string or a string into a number? and how would someone even turn a string into a number? i dont understand how that works.
I have a specific request or a general pondering really.I know you can create a sine wave type thing with as, could you then perhaps create movie clips, letter by letter that would move along and up and down on this sine wave?could you then, instead of setting the size and scale of the sine wave have it react to the input levels of a mic.i've been hunting for something that will help for a while and have drawn a blank
I am curious about where I can find sound files that I can use in Flash CS4 or some software that may be usefull in creating/editing/converting sound files to .wav or .mp3 for use in Flash. I should probably also note that although I do have Flash CS4 I am very low on funds for software
I looking into become a sound programmer. As I could find some sound analyzer would display a nice spectrum of color on bitmap. Which API do I draw a dot shape? Is it circle or line? Is it possible to resize the bitmap width and height after adding all the dots?
I'm trying to create some letter effects like waves, cascades, ripple etc.I saw these effects years ago in the old Flash MX/AS1 but I need to create them in AS2.
With Keith Peter's "Actionscript 3.0 Animation" book it's dead easy to make one that oscillates smoothly between two fixed values but I need one that varies it's oscillation randomly (within reason of course). Imagine the teeth of a saw, up-down-up-down-up-down, very dull. What I want is more like a range of mountains, the same smooth change in height but less regular.
posting after a long while, so i thought i'd actually follow the rules for posting,.. I am trying to get this waves thing done, here is the sketch [URL]I am trying to create those antenna waves as in making alpha go to 10% or so in a continuous loop....
I have some scrolling content (info). I've also made my own scroll bar.I want the scrollBar dragger to be positioned in relation to the info._y as the user scrolls info.I have created two vars: one that worsk out where info._y is as a percentage and the other that works out where the scroll._y dragger should be as a percentage...
Actionscript Code: var scrollBarPercent = Math.round(scrollBar.dragger._y / [code]........
also onMouseWheel working too.I need a small bit of code that takes the % of info._y and moves the scrollBar dragger to the same % but in relation to the Stage.height...so if projectGalleryPercent = 50%, make dragger._y 50% of Stage.height using scrollBarPercent.
How can i draw sound spectrum inside a display container other than stage?I tried to display it inside the rectangle movieclip but end up in failure.[code]...
I want to generate a variable number of random numbers less than 16 with no duplicate numbers
Ive posted the fla, and what i'm doing is generating a random number and putting it into an array then using a for loop to cycle through the array for each new random number to check if its already there. if it is, then i want to regenerate that number.
if you test the fla you'll see that all i get in my array is some lovely zero's and i sort of know why this is, but don't know how to stop it.
I am trying to convert a string having numbers to an integer.
//15 9's are there var str:String="999999999999999" var res:Number = new Number(str);
But it is not able to convert correctly as the the var res now has the value 100000000000000000. I know that the number has 52 bits of memory, then why is it not able to do the conversion?
create a function that picks out X amount of numbers from a set of numbers? So if X=3, then i need this function to pick out 3 different numbers from say a set of numbers (1, 2, 3, 4, 5, 6, 7, 8) and then stored it into X number of variables.
In saying that, X will only =2, and =5. So in the first instance, i'll need 2 random numbers from the set above that are not the same numbers, and second instance 5 random numbers from the set above (also no repeats of numbers). Then i need to be able to store those 2 or 5 different random numbers from the set into variables to call them with other functions.
I am using the draw() method of the BitmapData to encode a jpeg of part of the image. Now this should be easy enough given the object I want to draw to the bitmap is on the stage at design time so I know its location and dimetions exactly! Heres the code I have in place.
Code: var myBitmapSource:BitmapData = new BitmapData ( street.width, street.height, false, 0x333333); myBitmapSource.draw(street, null, null, null, new Rectangle( 96, 5, 571, 450 ), true );
I know for a FACT that no part of the street clip I am drawing out is in negative space, and it's registration is (0,0). However, it cuts off A lot of the top of my image. y=5 in the above rectangle is where I need the top to be, but it cuts the top off of the image... even if I change it to 0, it has no effect.
I'm trying to do some lean blitting for an object that rotates by rotating it once at startup and capturing a BitmapData snapshot of each 5 degrees. The problem I'm having is that the draw() method of the BitmapData object is only picking up pixels in the MovieClip that are below and to the right of the registration point. If I change the MC so that the registration point is in the top left corner, I sometimes get what looks like most of the pixels, but the entire object rotates into and out of the frame, since it's rotating around the corner and not the center.
