AS3 Sound Spectrum Experiment.

Compute Spectrum Experiment - Advice Needed
Hi,

I am very much new to AS 3.0 but I have used AS 2.0 for around a year or so.

I have been playing around with a Flash visualization using the soundMixer.computeSpecrtum feature which I found on the web http://www.communitymx.com/content/a...ge=1&cid=8E9A0

I have tried to create a single-line spectrum but have only managed to do this with the lowest frequency so only the leftmost line/bar is drawn.

Is there a way that I could somehow compress entire spectrum into one line/bar?

I have attached my fla and some an mp3 containing percussion samples so you can see how the spectrum is drawn for the lower frequencies.

Any advice on this would really be appreciated.

Thanks for reading,

Sound Spectrum
I'm creating a game which uses a sound spectrum to create the level, think Audio Surf. I know all about SoundMixer.computeSpectrum which outputs the spectrum live. I'm looking for a way to easily pre-compute the sound spectrum so the levels can be made ahead of time.

Is this possible?

Thanks!

Sound Spectrum
Hello everyone I am working on a project where we have to create a music player.But there is a problem that the client wants sound equalizer for that
I came to know that it is possible in actionscript3.But I am very new to it .If anybody have an idea for that or any tutorial available for that using sound object.
Thanks in advance

Sound Spectrum
Hi, i followed the tutorial here regarding the sound spectrum.

Now i only wanted to have 6 bars wich moves along with the music.

So instead of making a for lus wich goes trought 256 items i only made it go through 6.
But i was wondering if this is the correct way to do it.

I have 6 bars on my stage (balk0, balk1, ....)
Code:

init();

var s:Sound;
var ba:ByteArray = new ByteArray();

var tween:Tween;

function init():void
{
   s = new Sound(new URLRequest("music.mp3"));
   s.play(0, 1000);
   
   this.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
}

function enterFrameHandler(e:Event):void
{
   SoundMixer.computeSpectrum(ba, true);
   
   for(var i:uint = 0; i < 6; i++)
   {
      var num:Number = ba.readFloat() * 200 + 150;
      
      this["balk"+i].height = num;
   }
}


ps: sorry for my bad english, but i'm dutch

Spectrum Efect On A Sound
Greetings.

I was taking a look at the wonderful Flashkit's tuturials, and saw one that particularly interesested me : here

This is a great tuturial, but it uses an imported wav sound to play, I wanted to do the same effect with an external ".mp3" sound, so that the .swf wouldn't got too big.

But I don't seem get to work with it, (the spectrum stays still) could you give me any tip? I would be very glad!

Thanks for your support!

Sound Output Spectrum
Have you seen on www.flashkit.com that you can download sound files and there is a preview console. Well my question is does anyone knows how did they capture the sound output spectrum values of the selected playing sound? I think that preview console is great!

Sound Spectrum And Praises
I just stumbled across this site, and am so glad that I did - the tutorials are laid out so simply and easily. It would be nice if the videos were in flv format instead of mov, because for some reason it doesn't player properly in firefox with mediaplayer - so I have to load it in quicktime which slows my computer to a crawl.
Anyways, great tutorials!

I came across the sound spectrum tutorial, and was surprised how simple it was to do that effect. I'm a bit of a beginner at Flash - I have lots of experience with scripting and programming, but Flash is still a bit new to me. What I'm wondering is whether it's possible to instead of using a pre-created sound file - pull audio from the user's computer instead. So if the user plays music, and hits Yes on the security message that popups up in flash - then you could listen to the audio and use that to display the audio.

Maybe you could write a tutorial on it, or maybe someone can just fill in the pieces needed for that. Again awesome site, bookmarked it

Sound Spectrum Display 2
A couple of other quick questions on the code. Is there a way to have the visualizer run without the audio playing? And is there a way to extend the width of the spectrum?

var s:Sound = new Sound(new URLRequest("Valerie.mp3"));
s.play(0, 1000);

var ba:ByteArray = new ByteArray();

addEventListener(Event.ENTER_FRAME, loop);

function loop(e:Event):void
{
graphics.clear();
graphics.lineStyle(1,0xff9100);
//graphics.beginFill(0xFF9100);
graphics.moveTo(-1, 300);
SoundMixer.computeSpectrum(ba, false);
for(var i:uint=1; i<256; i++)
{
var num:Number = -ba.readFloat()*50 + 75;
//graphics.drawCircle (i*2, num, 10);
graphics.lineTo(i*2, num);
}
graphics.lineTo(920, 150);
graphics.lineTo(0, 150);
graphics.lineTo(-1, 150);
}

Sound Spectrum Display
I've been experimenting with the Sound Spectrum Display tutorial with much success though I got stuck on trying to make the spectrum line be more curved and smooth like a sound wave. I was trying to use the curveTo function but I just can't get it to work. Has anybody had any luck smoothing out the rough edges of the audio visualization.

Working Sound Spectrum Analyzer
Hi,

how can I make a REAL spectrum analyzer in flash? it is possible since I think the tiny sound players in the flashkit sound archive use REAL spectrum analyzers too.

but HOW can i build one? please help! please...

Sound Spectrum Issue With Firefox
I am using the sound spectrum class to create an equilizer using the classes from http://www.everydayflash.com/blog/in...r-in-flashas3/

I have got it to work fine locally in the flash IDe when i go to preview the file however when i go to preview the file in firefox it throws errors. If i preview it in IE then it shows fine.

I have previewed other sound spectrum stuff and i get similar errors or sandbox violation errors. I am using the latest flash player too.

On a mac in firefox 3 it just shows it with no EQ, on firefox 2 on a PC it gives me erorrors and it IE on a PC it works perfectly.

Not sure why i am getting the errors if it shows fine in the IDE but not when i preview it in the browser. Am i doing something wrong?

Sound Spectrum Data Without Playing?
Hi, I've been searching around lots of forums for this...

Can you access sound data (like computeSpectrum) of a loaded sound object without actually playing the sound? ie. to show an amplitude graph for an entire mp3 clip as would an audio sequencer.

Thanks in advance...

Cross Domain XML, Sound.Spectrum, And FMS 2
I've created a custom video / audio player which gets it's video / audio content from a Flash Media Server. I'm trying to use SoundMixer.computeSpectrum() to create a nice audio spectrum line. I'm getting this sandbox security error. I'm already using a crossdomain.xml to allow another flash object to call a webservice and it works fine, but since my videos are on another server, I'm not sure what I should do to get this working? Has anyone run into this issue before or have any words of advice?

SecurityError: Error #2123: Security sandbox violation: SoundMixer.computeSpectrum: http://www.MYSITE.com/Flash/player.swf cannot access rtmp://192.114.20.88/Videos. No policy files granted access.

Advanced Filter Effects/Sound Spectrum
hi,

i've watched the tutorials on advanced filter effects and sound spectrum display for as3.
Now I wonder if there's a possibility to "offset" the blurry circles that are dynamically created by the sound from these dots. In other words: I want the circles to be off the stage (at the bottom) and the glowing spectrum to be on the stage, about 30 pixels from the bottom.
The effect is shown in a screenshot of the Zune Media Player Software (http://shadowsillusion.com/blog/wp-cont ... ection.jpg) at the bottom there's a orange/pink glow.

thanks for posting a solution

Sound Spectrum Display Of Music File

My Experiment
hi,

I'm not sure how to explain it best, but I'll still try.

I have a movie clip that contains buttons and this movie clip itself it attached as a content to a scroll pane. Now when I click on the buttons, I want to be able to perform a gotoAndPlay in the main scene.

If you see the attached file, when I click on the next button, it does a 'gotoAndPlay' to the frame named 'next'. There's a movie clip 'scroller' with a button 'best shots' and the scroller is attached to the scxroll pane. When I click on the 'best shots' button, i want to be able to perform a 'gotoAndPlay' to the 'loadimages' frame.

Thanks for any help

Help Me With This Experiment
I have read a lot about the best file format for import images into flash, so I tried the next experiment:

I use the "famous" Dune.tif image of the samples from photoshop, I changd the image size from 600 x 600 px to 300 x 300, and save It as .jpg and .png file formats (the same image) and I get these file sizes

Dune.jpg (80% quality), size 48 Kb aprox
Dune.png (default settings) 172 Kb aprox

Then I imported these images to flash in separates documents, converted the bitmaps to graphic symbols and made a motion twen of 50 frames from alpha 0 to alpha 100. I saved both fla and I get these file sizes

exppng.fla = 220 Kb
expjpg. fla = 44 Kb

Up to here all looks "logic" bigger input = bigger output

But here is the interesting detail, the swf file sizes

expjpg.swf = 32 Kb
exppng.swf = 8 Kb 8 Kb

So I would like if some of you in your spare time, try some variations of this experiment, and post your resoults here, to get a more definitive conclusion...

Becouse so far I have found a reason to use always PNG to import to flash, and is a reason based on one of the most importants facts in WEB, file size. But before that I would like to probe that this is a "general rule" and not and "unique event"

(sorry about my english)

E In 3D Experiment

Little 3D Experiment
The main engine is a variation of the one in the tutorials, but I added other features. You can fire a ball thing by clicking, and hitting shift releases a small ball that I tried to add minimaly physics to. Space is jump, and W, S, A, D are moving keys. You can jump onto those boxes, but it's quite awkward. I'll post the source, but it doesn't have comments, just directions to certain functions.

Link'd: http://www.sheezyart.com/view/166881

The physics-type balls seem to get absorbed by the boxes, so when someone asks, I just say that the boxes are jelly...

Time Experiment
what I want to do is; have two buttons, the user clicks on the first, then the second. Is it possible to return how many seconds past between the two clicks?
Otherwise if it is simpler, can the second button take the user to one frame label if less than three seconds lapsed between the first and second click, or another label if they took more than three seconds?

Im not that familiar with scripting but I have a handle on the basics.

Video DJ Experiment
Hey all,

I'm still starting up with AS and i think its fun as hell and ive been trying to come up with some new ideas. My first idea is about being able to scratch and scrub over a movie clip like is if it was a vinyl.

I got the idea from an advertisement of a guy eating a hotdog really fast in one gulp(i think it was for MasterCard) By mousing over the image you can scroll through the frames of the movie. One night i was just playing around with it and i was making the guy eat the hot dog to the beat of the music i was listening to and i thought it would be cool if you could somehow record all the mouse actions and have flash spit out a .mov or something that has all those same actions in it. That way you have a movie that glitches and scrubs to the beat of a song for use in a musicvideo or something.

Well, i wrote the code and got it to work by recording each frame that the mc is on 30 times per sec, outputting that number sequence and then bringing it back into another fla that creates an array of the sequence and cycles through each frame in the exact order as before.

This works really well and produces an exact replica, but the only problem is i cant use a swf for a music video. I need something editable that maybe doesn't rely on actionscript.

I'm open to all suggestions and comments about my idea. also if anyone knows a program that already does what i want then let me know(but that's no fun!).

Q; On Math Experiment
this draws a nice shape:
(small circle mc named 'sq' on stage w/ alpha 20, and code on empty mc)


PHP Code:



onClipEvent(load){
    _root.sq._visible=0;
}
onClipEvent(enterFrame){
    i++;
    duplicateMovieClip(_root.sq,"sq"+i,i);
    _root["sq"+i]._x=Math.cos(Math.PI/180*j++)*100+300;
    _root["sq"+i]._y=Math.sin(Math.PI/180*(k+=0.4))*100+200;
} 




how'd i stop it once the cycle is completed?

thnx !!~~

Key Class Experiment
I woke up today and i had idea of doing some experiment in flash. Im a very poor coder but came up with something that might look a bit cool to some of you. It has to do with a Key class. I won't tell u much, just to go the link and click on the red/orange box and start typing.

http://www.vdschee.nl/~angelique/euro/keyClass.htm

To see even cooler effect start typing random letters really fast.

VB6 + Flash Experiment
Hi. I'm considering some different soloutions to to a problem at the moment and am wondering if anyone has any ideas on different kinds of solutions.

I am required to publish some standalone flash onto a USB key for publicity purposes, and as a requirement, need to initially store users details on the key somewhere. Doesn't really matter where or in what format, but the users simply need a way of indentifying whose key is whose?!?

I'm currently toying with the idea ofembedding the movie into VB6 so that I can publish as a standalone EXE, which could then be AUTORUN once the device is plugged into a pc.

I'm thinking of VB because obviously I need some method for file IO, as the user infomration must be stored on the device, ruling out any kind of flash cookie (I think).

If I'm wrong and flash cookies could be directed to the usb device I would have no problem publishing a simple swf onto the device without the need to use vb.

Any Ideas anyone??????

Fun Experiment ... Why Is It Not Working?
i'm trying to create the illusion of cracking glass onMouseDown

so when the user presses the mouse button i take the current coordinates, move blank MCs there and then move them off in random directions, i then take another set of blank MCs and use those to draw lines from where the mouse was pressed to it's current location.

i think this will give the appearance of cracking glass

here's the code i have so far

PHP Code:



for (i=0; i<Math.random()*4+2; i++) {
    _root.createEmptyMovieClip("crack"+i, 10+i);
    _root.createEmptyMovieClip("line"+i, 20+i);
}
onMouseDown = function () {
    mouseX = _xmouse;
    mouseY = _ymouse;
    crack[i]._x = mouseX;
    crack[i]._y = mouseY;
    crackle();
};
onEnterFrame = function () {
    crackX = crack[i]._x;
    crackY = crack[i]._y;
};
crackle = function () {
    crack[i]._x += Math.random()*10-5;
    crack[i]._y += Math.random()*10-5;
    _root.line[i].lineStyle(1, 0x000000, 80);
    _root.line[i].moveTo(mouseX, mouseY);
    _root.lineStyle[i].lineTo(crackX, crackY);
}; 




there are no symbols in my movie so just copy and paste that code onto frame one and you'll have what i do. but it's not working yet

any help would be appreciated
thanks

SWF Parser Experiment
I played with SWF format (trying to get an Actionscript solution for online SWF manipulation/authoring).
Here you can find a sample AIR application to extract all images from any swf file and a source example with main Actionscript functions for SWF format parsing:

Online Experiment: Can You Help?
Last edited by mediaRob : 2005-03-04 at 06:37.
























Would you please spend three minutes completing a very simple interactive online experiment? The experiment involves waiting for a square to appear and clicking on it as soon as possible. This is repeated twenty times.

You can access the test at http://lab.webnwap.com.

I am conducting the experiment as part of an assignment for an MSc in Interactive Media Production. By completing the experiment you will be providing me with several valuable elements of data allowing me to analyse human interaction with computers.

Would you please forward this to anyone you believe might be interested in participating in the experiment.

Thanks for your help,

Rob.

ps. sorry if you believe this to be spam, or an inappropriate posting.
