ActionScript 3.0 :: SoundChannels, Soundtransform And Volume Question(s)
Feb 2, 2012
Trying to reduce frame overhead in my game, im trying to figure out how to speed it up.These are some 'simple' questions if you know your way around sounds and channels so i'm hoping you'll read on and perhaps give me some insights.
I'm noticing that playing soundclips sometimes make it stutter so im looking for the best way to use sounds and channels.The main question is below: how costly is a soundtranform.volume and is it persistent on a channel?secondairy; does it matter howmany soundclips i drop into the same channel?What i noticed: The channel.soundtransform.volume only works after playing the sound. Q: How costly is a channel.soundtransform.volume?&; Will it stay this volume on the next sound that plays? or do i have to reset it each time?
Also: playing a lot of sounds in 1 channel isnt a good idea.So i created a channel for each gameobject that could produce sound.On each sound play i calculate distance from main player and set volume accordingly.
1: I could just pre create like 10 channels set the volume from 0.1 to 1.0 accordingly then play each sound in the specific range channel This way i wouldnt have to do soundtransforms on the fly.If however every sound producing object would be at the same distance it would clutter 1 channel with a lot of clips to play at the same time.
2: I could pre create 10 channels as a queue. On every play i would pick the next free channel, looping & wrapping through them as i go.
Here however i will have to set the soundtransform volume again on each play according to distance.

I have this code, and it works perfectly fine for the most part:
soundTrans.volume = 0.1
What this does, it plays the Sound at about 10% of its total volume.But about 1 out of 10 times, there seems to be a bug, that causes it to play 100% of its volume for like a split second then it goes down to the 10%.Like if the soundTransform is applied after the sound has already started playing, and the Player just sometimes cant synchronize it perfectly? I tried to play around with trying to set the soundTrans BEFORE starting the channel, like:
soundChannel.SoundTransform = soundTrans;
but to no effect, it seems the player Applies the soundTransform always just when the Sound starts playing.(or actually just a bit after)This is especially annoying if you are trying to Fade in a music slowly maybe over the course of 5 seconds, and then it starts with a big BANG, and then it goes down, then it fades in, ruining the whole effect.

I have a video chat application where there can be 6 participants. What I would like to do is give the option to each publisher to control their own stream's volume. The code I have looks like this.
[global]
private var volumeTransform:SoundTransform;
[In the init method where ]
outgoingStream = new NetStream( nc );
[Code]....
A possible solution can be this : Calibrate the slider and set the microphone gain, a gain of zero effectively is mute and a gain of 100 is full volume.

If I call the play() function of a Sound, which returns a SoundChannel object, will the SoundChannel still linger around after the sound clip is finished playing and eat up resources? Or will Flash's garbage collection scoop it up?

I'm trying to synchronize 5 mp3 (128kbs 44hz stereo), each one in a different SoundChannel, and some animation. I've red a lot about the variable delay of the soundChannel, and how the "position" property return where the soundchannel should be, and not where it actually is. But I didn't find any real solution to these issues.
For the moment what i'm doing :
- load the 5 mp3 in their soundChannel
- start the soundChannels
- put a timer to check the first soundChannel position to change the animation
I've tryed to solve the delay between the soundchannels by resynchronizing them after a few seconds to the first soundchannel position, but it's only getting worse.
I'm using Flash CS4 / AS3 but I can easily go back to AS2 if needed. And I can embed the mp3 in the swf or using any other audio format.

So I followed a tutorial and got my video player working perfectly, then hit a wall when trying to replace the volume slider with volume up and down buttons.
attached is the current working video player, I didn't bother uploading the .XML and the .FLV files, but I will if you're interested.
Here is the code which handles the SoundTransform object, but I can't figure what to apply to my EventListener on the Volume Up and Down buttons.

I am really close I can feel it. I am doing something stupid I know. I have a file where one button simply controls stop and play of a looping audio stream. (by overlapping the buttons and making them visible or invisible depending on buttonClick) I have it where it does work for stop/start but I really need to to Play/Resume.

Somehow my class is giving me the following error, after I added a SoundTransform object.What am I missing The issue is somewhere with the
private var soundTrans:SoundTransform;
soundTrans = new SoundTransform();
Why would that be happening?

I've created a small music player with a sliding volume control. I'm having trouble with the volume. Though it does control volume properly, if I set the initial volume to less than 100%, the volume always starts at 100% until I move my mouse over the player. At that point, the volume changes to whatever the initial volume is set to.Is this a flash bug, or am I missing something? Here is the affected code (code for other buttons/functions omitted for brevity):
var song_initvolume:Number = 100;
slider_1._x = groove_1._x + song_initvolume;
playSong(0,song_play);[code]....
I'd like to be able to set the volume at say 50%, but the above mentioned behavior happens each time.

I'm building a video player and am kinda stuck at the volume slider part. It's a YouTube style vertical slider, meaning if the slider is in the top position volume should be 100% and if the slider is dragged to the bottom position sound should be 0. Currently it's doing the opposite of what I want :(
Dragging the slider down will make the sound louder, while dragging up lowers it.
Here is my code below dealing with the volume slider.
[Code]....
The (-4) is an offset value so when you drag it all the way to turn it off, it's 0 and not 4. I need to reverse this somehow, so the traces above will swap... going down will make userVolume = 4 and going up will make it 30.

On a recent project I am working on, I created an event-based sound engine. Different components within Flex will be registered, and then the controller will listen to events and handle the information correctly. So, it just takes a custom SoundEvent or ChannelEvent to alter one of the channels, or play a sound.
I can not quite figure out what is wrong with my code, and I am finding myself snow-blind to the issue at hand. At first, I was going to rewrite it but I figured it would be better to learn from my mistake. Also, I realize that this is not correct for streaming sounds, but I am working off a local sound library until I get it up and running smoothly.
Here is the code for the SoundEvent:
package code.events
{
import flash.events.Event;
public class SoundEvent extends Event

I've got a serious of games which in turn load off a main main swf.I have mute and unmute buttons on the main menu and the same buttons in each game.When I unload/load a game I want the volume to stay as it is so they player doesn't have to keep turning the volume off. AudioOff is the button shown when the volume is off and AudioOn is the button shown when the volume is on.The code I've got now keeps the volume on or off through the games but the buttons aren't showing up correct with this code..
if (SoundVolume.volume == 1)
{
AudioOn.visible = false;[code].....

I converted the slider bar and slider button to buttons. Then, I made the slider button into a movie clip.
Here is the code I placed while slider button was a button:
Code:
on (press) {
startDrag(this, false, left, top, right, bottom);
}
[Code]....
It seems right to me but I don't know. The movie button slides down the slider bar but it just doesn't affect the volume. Going to try to attach my FLA to offer better insight. Just tried to upload it and no matter if it's FLA or zipped FLA, it says it failed.

I have a tower defense game that I am working on and I'm in the process of adding sounds. Each tower plays its own fire sound when it fires. However When I have 5+ towers of the same type firing at the same time the volume gets louder.
Here is my game as is, the sounds are only in testing stage right now and I am aware that they can get annoying with the current set up.[URL]..
Most noticeably are the air towers. if you feel like listening play my game and first place 1 Air (blue) tower on screen. When the first air wave starts (lvl 4) hear the one tower firing alone and then during this stage add a 2nd tower and the volume almost, if not, doubles.

I'm a designer that inherited a project with a volume slider. I'm not that good with actionscript yet and haven't been able to figure out the code. The volume and slider starts at 100%, and I need it to start at 50%. Can you tell me how to set both the volume and slider at 50%? I'm sure it is a simple solution but I can't figure it out. I tried a few things but have not been able to get it to work correctly in both the volume level and start position for the sliderHere's the code on the 2nd frame of the mc:
Code:
stop();
var NiVol:Sound = new Sound(_root.Container);

My site is nearly ready, but I still want to add two buttons: one to set the volume to a normal value; another one to set the volume to 0 (like a mute button). I don't have a background music, I just want these two buttons to make effect on several other buttons with "click" sounds attached.
I have my buttons ready, and tried using this code for the "no sound" button:
ActionScript Code:
on (release) {
set.volume(0);
}

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?

On a movieclip I have a sound that plays whenever the movieclip is dragged over the right object. It works but the problem is that it lowers the volume of the background music (which I don't want). I think that if it were possible to change the type of sound using ActionScript to an Event sound it would work.Here is the code:
ActionScript Code:
unlocking = new Sound(this);
unlocking.attachSound("unlock");
unlocking.start();

I know how to make a slider that controls the volume from 100 to 0. But is there a way to boost the volume in Flash?
I want the movie to open with the volume slider at 50% (visually) but the volume level (audibly) to be 100%. Then lowering the slider to 0% will cut the audible volume to 0 but raising the slider to 100% will boost the volume audible to 200%.

I've been trying to create a volume slider for about two hours now and it just doesn't work. I followed Ilyas' slider tute and Kirupa's volume control tute both to the letter and now no sound loads, the slider doesn't control anything and it sticks to the mouse when you let go i.e. it still drags left and right across the slider after you release the mouse button.I can't show you my code unfortunately as I just got really angry and wiped it.Could someone please either show me exactly how to load a sound and control it's volume in one tute (Kirupa uses a different method from the "load sounds using AS" tute to load his sound in the volume tute but he doesn't explain it. I don't want his source .fla+mp3.) or make me a .fla that loads a sound called "music" (linkage name) and controls it's volume.
