Actionscript 3 :: Overlapping Sounds And Clipping In StandingWave3?
Aug 22, 2011
I've been playing with the dynamic audio library standingwave 3. Almost the first thing one notices is that if one tries out the code samples in the developer's guide, namely this code:
[code]...
then one gets a really unpleasant sound and trace messages that read "AUDIO CLIPPING". The developer explains in one of the issue reports on github that you need to reduce the gain of samples when you mix them together to avoid this, and that there's no easy way to know dynamically how much reduction is needed.My question is, how is it that stangingwave2 seems to have dealt with this automatically? For instance, the code quoted above did not clip in SW2. Likewise consider this SW2 example demo - if you increase the sustain and hold (the S/H sliders) and press one of the sequence buttons, multiple tones will overlap without clipping, even though the source doesn't show any apparent sign of changing the gain or the volume of the sin tones, they just get mixed together.What's going on here - did SW2 have some way of dealing with this automagically, or is there some robust way of generally overlaying arbitrary numbers of sounds dynamically without causing clipping?

I am trying to simply have it so that when you put your mouse over the little blue guy, the sound repeats faster but does NOT overlap, infact, I don't want the sound to overlap at all. Also I want it so the sound stops playing on the next scene.

I want to trigger a sound from my Library (linkage is: INM_Alarm). I have a problem with the code below. When I click the button a second time the sound should stop, but I get an error like this:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at M_fla::MainTimeline/alarmFunction()[M_fla.MainTimeline::frame1:48]
Code:
alarm_btn.addEventListener(MouseEvent.CLICK, alarmFunction);
var sndAlarm:SoundChannel;
var alarmPlaying:Boolean = true;
function alarmFunction(evt:MouseEvent):void{
if(alarmPlaying){
var sndAlarm:INM_Alarm= new INM_Alarm();
sndAlarm.play();

I am using an xml based slide navigation shell that uses next and back buttons to page through content.
If I use SWFs with embedded audio (which I need to do sometimes) the audio will overlap after I leave the slide, SoundMixer.stopAll() is not doing the trick. I think removeChild may be the direction I need, but I'm not sure how to implement so far.

is there a way to play sounds one after another avoiding overlapping without using the SOUND_COMPLETE event by SoundChannel? I have a few sounds to be played in order and using SOUND_COMPLETE would take me to add to many listeners.

The problem that I am having is that stopping sounds using a basic "mySound.stop()" command, or using "setVolume" to fade it out instead - causes clipping. I understand that, technically, it is not "clipping" (this is part of the reason why I can't find any forum threads about this). What is happening really is that the sound card is interpreting going from an average dB level to zero makes a square wave, and thus the popping sound. For example, imagine that each dot is a sample in a WAV, and as you can see the straight vertical line occurs when the sound is stopped:BUT, what I am confused about is that this does NOT ALWAYS happen. I find it hard to believe that I am just getting lucky and hitting the stop button exactly at a moment when the wave is at zero (or really close).

I followed the mp3player tutorial (part 3) from [URL] and got it working fine. Only problem is that the setVolume I'm trying to use with my music is affecting all my other sounds - button sounds and background sound. I'm aware of the createEmptyMovieClip/attachSound approach and got it working on my other sounds. But Lee's tutorial-mp3player is using a slight different technique, and so my normal approach doesn't quite work.

I want to synchronize sounds perfectly to do a kind of Audio Mixer, using different sounds. [URL] does it perfectly, I've been researching and researching and I just don't know how to do it! How does [URL] synchonize audio so perfectly? you can even change sounds and the new ones will come on time! How do I do that? Is it just Action Script? or something else?

I noticed that for some reason whenever I use the 3d rotation tool on an object inside of a clipping mask that the object releases the clipping mask. Are 3d objects not supported within clipping masks? Is there a way around that?

The last 2 characters or so are partially obstructed by parentheses.
For example, when I type: "stop()" it looks like "sto()".

I have a simple flash video player that streams the video from a streaming media server. The stream plays fine and I have no problems with playing the video and doing simple functions. However, my problem is that on a mouse over of the video, I have the controls come up and when I do a seek or scrub on the video, I get little weird boxes that show over the video - like little pockets - of the video playing super fast (you can basically see it seeking) until it gets to the point it needs to be at and then these little boxes disappear.

Notice that the lineTo completely leaves the UIComponent and Panel.How can I cause my UIComponent or Sprite, Or Panel for that matter, to be cropped/clipped? I realize I could just change the hard-coded 2222's to something more reasonable, but I need a generalized solution to this, since the actual project doesn't involve hard-coded values that I can alter, but works with dynamic data.

I have a container with a vertical layout inside which I have two other child containers "A" and "B". n the first container "A" there is a component that I would like to resize dynamically based on the available display size. To to that I tried listening to the resize event of the main container and do my measures accordingly. That works somewhat until the parent container reaches a clipping size : container "B" gets clipped earlier than "A" because it contains much more stuffs : As soon as the parent container reaches "B"'s clipping size, it does not resize anymore (so no more resize event either) thus preventing me from updating my component's display in "A".

I am trying to figure out bitmapdata and was attempting to draw 2 ellipses as sprites,capture the bitmapdata and then spit them out with draw(). The problem is, there is some nasty clipping and I don't know how to get rid of it. I have tried using rect and messing with the draw parameters but nothing seems to work.
Code:
public class fhParticle extends MovieClip

I want to create a MovieClip symbol of a certain width and height, but with content that extends outside its boundaries, with the option to have the external content be clipped/hidden or visible.
In Flex, the solution would be to create a group with .clipAndEnableScrolling = true.
Is there a way to do this in Flash CS5, or will the symbol always resolve to the size of its contents?

when I move the camera around my scene the rendering at certain points is odd. Triangles become missing and it seems as though its just not working correctly. When you move the camera beside the cube, triangles along the side of the cube go missing. Is there a way I can turn the clipping off? Should I use more triangles? Is it a material/render engine/viewport problem?

I have a Plane and I try tweening a MovieClipSprite on it. I run into trouble when I try to tween near the points where both segment triangles meet (I have kept both segments as 1), While moving near these points the Sprite disappears. I can tell it goes beneath the Plane because when it reappears it does so gradually and I can see it's lower half appearing as it moves away from these points. Increasing the segments obviously deteriorates the performance further as this begins to happen at other points as well. I am pasting some relevant code var planeMaterial:BitmapMaterial = new BitmapMaterial(texture.bitmapData, {smooth: true, precision: 4});

I have a film with 4 scenes in it: Here's a link to the film and as you can see the film does not play the music the second time because of the StopAllSounds function which is probably the wrong code to use. The first scene is just a button with 1 frame, a stop action and a music clip. The second scene is the film. The third scene is the credits fourth scene is a Play again button. I have a Stop all Sounds action on the fourth scene because if I do not use it and I press the Play Again button, the music from the first song keeps playing but also the music from the film starts up again so it starts to play twice. What I want to know is, how do I get the music to stop at the end of the film but start up again once I hit Play Again?
I am using Flash CS3 if that helps and using Actionscript2.

I have been trying to import clipping paths into Flash, but the images look fine, except for the white outline around the imported clipping paths. what I could do to remove this. The clipping path looks fine when I drop it on the same color background in Illustrator. I'm using CS2 and Flash 8.

var snapshot:ImageSnapshot = ImageSnapshot.captureImage(someSprite);
var file:FileReference = new FileReference();
file.save(snapshot.data,'abc.png');
n the above code I am able to capture an image.But I also want to apply a scalingMatrix(for zoomIn/Out) and a clipping rectangle to it. How to do it? I tried capturebitmapdata too, but with that I can't even get a proper image. See here. So I don't want to use that.

I wrote a collision detection class that works off using BitmapData.hitTest. Basically, every update, the .draw method is called and then two BitmapData's are hitTest'ed against each other to see if there is a collision.It works pretty well, however if I start rotating the source MovieClip I use for the BitmapData, the transformations don't get registered in the draw method. So what I did was pass through a Matrix in the draw method. That works. But here's the actual issue. If I output the BitmapData to a Bitmap on the stage, I see that Bitmap is, in fact, rotating, but now it's exceeding the bounds (width and height) of the BitmapData. Which is cropping / clipping the image of the source MovieClip.
UPDATE: Basically, when the Bitmap clone of the MovieClip rotates outside the positive co-ordinate space, it doesn't get drawn. It rotates outside the bounds of the BitmapData set width and height. I can multiply the bounds by 2, and then center the bitmap inside the set bounds, but then the origin point is never fixed and the object is always being moved around. Works pretty well, but makes aligning the object to any specific point impossible.Here's my isolated test code. It requires you to have a MovieClip on the stage named "iTest". I used a fairly vertical arrow shape (higher than it is wide) so I could keep track of rotations visually accentuate the clipping problem:
var rotateTimer:Timer = new Timer(10);
function rotateObject_init():void

I'm working on a game where clicking an object causes cartoon animals to appear. The animals stick around and do a little animation for about 5 seconds, before disappearing. I'm having a problem where if I click the object before the animal disappears, another appears on top of it.This is my code:
on (release) {
i = Math.ceil(Math.random()*3);
if (i == 1) {[code]...........
I'm trying to find a way to make it so "on release" is disabled for a set period of time once it executes, enough time to ensure the animal movie clip playing has disappeared.

I have a movie clip with hit zones over buttons. It looks like a cam corder and when you roll over them a thumb moves to that button and when you click. The thumb presses on the button. That all works great. I want to put buttons in the main scene over top of these that will change things on the screen when you click it. And get urls of the videos that I have on my website. But when I put the hitzones over other hitzones the ones in back dont work. Is there a way to make them both work or am I going to have to make everything contained in the movie clip? So in short can I have two buttons on top of each other that do two different things?

This seems like such an easy thing to do but it's driving me crazy. Sorry if this is a simple question. In a site I am building it is necessary to have a large movieclip overlaid over an image gallery. This movieclip controls scrolling so has a rollover listener attached, but of course the gallery pictures also need to have button actions. I cannot get them both working at the same time. How can I make it so that rolling over a movieclip doesn't disable the rollover for any movieclips underneath it? Here is a very simple example of the problem. Where the two buttons intersect, I want for the rollover to trigger them both: [URL]

Has any one encountered this problem or know how to solve it?
