Actionscript 3.0 :: Changing Volume With SoundChannel
Jun 1, 2009
Code: Select allprivate var musicFadeAmount:Number = 0.005; // Amount to fade the music
// Helper function to change volume
private function SetVolume(vol:Number, sc:SoundChannel):void
{
[Code].....
I run the last two rows in an ENTER_FRAME loop, and from the trace in the SetVolume() function I can see that scMusicIdle changes it's volume like it's supposed to, but scMusic keeps it's volume. I can change the volume when I play the sound with a new SoundTransform().
how to fade between two tracks in a better way I'm all ears. If it makes any difference it's an AIR 1.5 app.
AS2 -> AS3 migration: doncha just love it?!have a look at the attached code. selection one makes us anew sound and gets it playting, great. then we need to adjust thevolume so we read in the files that:You can alter the volume and panning while a sound is playingby setting the pan or volume properties of a SoundTransform objectand then applying that object as the soundTransform property of aSoundChannel object.great, so selection 2 in code below should do that, right?
I just finished a simple music player... For testing purposes. I upload it in the following address:http:[url]....with 10 music songs that I had recorded from radio stations(added the last 2 twice for testing).The problem is that when a song has totally loaded, stop action taken needs about 1 second to be applied!I.e. When I press "STOP", the sound continue to play for 1 sec before stop. When I push "pause" it takes one second for the music to stop!
However when using resume (second time pause) the sound starts instantly! Thus I guess there is an issue with stop()function of the SoundChannel object that I am using to stop the sound. Also notice that when unpause the music, it continue ~one second before the last sound - which means that I saved the soundChannel.position number (and also call soundChannel.stop()) in correct time, but it didn't stop immediately - bug!?
This only happens when the application runs through a browser(plugin v. 10) - programmed in CS3.
PS1. Notice that ,this also happens when I change Volume too. Thus because Stop and Volume are parts of SoundChannel, I guess there might be a bug with SoundChannel in online plugins..... :/
PS2. Notice that ,this also happens when I close the browser (firefox). Even if browser is closed the music continue for 1 sec the same way as when pressing stop!.. Thus I guess it's flash bug!...
I'm currently having problems using the volume property of the SoundTransform class to change the volume of the sound effects played in the game I am building and was hoping someone here would be able to point out what I'm doing wrong. Essentially I am setting the volume property to various values between 0 and 1 but the volume is not changing in the slightest!
In the main menu of the game there are two slider bars that can be used to adjust the volume of the background music and sound effects respectively. When the user moves the slider a value between 0 and 1 is passed to the SFXHandler class which I have created to handle all sound effects in the game.[code]Can anyone see why calling SetSFXVolume would not change the volume at which the sounds were played?
What Im looking to do is decrement the volume level on each iteration of a looped sound.[code]How do I check each time it loops? I'm currently storing all playing sounds by ID inside a Dictionary object. Keep in mind that there will be different sound playing. I wasn't sure if I should be using a SoundChannel here either.
Cannot read property (or target) a Sound thats playing in a SoundChannel.... in this case I am refering to a class the extends the Sound class (SoundEffect class), that is currently playing in a SoundChannel. Each SoundEffect has a volumeLevel property that I would like to restore once I have unmuted the SoundEffect's in my application. I cannot figure out how to target that property once its playing in the Channel.I am extending the Sound class:
ActionScript Code: public class SoundEffect extends Sound { public var ID:String;
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.
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].....
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 wondered if there is a way to find out from the soundChannel the url of the sound it is currently playing. once I found out its url, i can than use its name to call something else.Or anyway to find out the sound that is playing on a soundChannel.I will know which channel to look into, but different sound will be loaded into this soundChannel.If this is not possible, i thinking along the line of overloading SoundChannel play method so that is fires an event when the sondchannel plays and also find out the name of the sound file it is currently playing.
I am trying to build a simple player inside my swf file. The code is a bit messy but it seems to work.I´m using a soundChannel for Playback..I´m trying to figure out how to have the player play the next song once the previous one has reached its end.Do I add some sort of EventListener to the soundChannel?[code]...
i have a little flash-player with a playlist and so, it plays normally a vlc-mp3-stream but has an extended prelisten-function (wich plays the mp3's directly via http, secured with a password)i've got an array with 2 Sound()-objects (for preloading purposes), the code looks like this :
this works for the vlc stream (which is not continuos), but not for the mp3s on the http-server in my opinion, this doesn't makes sense..except, maybe the recent CSRF-hardcore-paranoia [URL]
PS: i use AS3 with flex_sdk_3.2.0.3794 and flashdevelop (i activated flash10-support, but it still works in fp9)
I'm having some problems with a script.I developed the app on a mac. It's intended to be both on mac and windows and also air and swf (I save data or not depending if it's installed or not).I've tested it on mac and several pc (winXP) but on win 2003 server and win 2008 server I get an error. Also on a winXP without flash player installed (through the projector) breaks at the same point.The problem is on the red line. It does always work right, sound loads, plays and when it finishes the event is called (in this case it loops). In other cases when sound completes the event should load a screen or so but, as I get an 'Error #1009: Cannot access a property or method of a null object reference' so the movie stops.I need all sounds to be inside flash so I put them in library and set their classes as com.escacs.sound.* (there are many sounds) I can't understand how mainSC can be null or undefined if the previous instruction initializes it.
I was debugging sound in an app and decided to make a little test case as I kept getting odd errors... well I just moved to a new desk yesterday so hadn't hooked up speakers yet. Here's the test:
var backSound:Sound = new bgSound(); var backChannel:SoundChannel = backSound.play(0, 999); trace(backChannel);
bgSound is just a library sound... if my speakers are unplugged from the sound card backChannel returns null. If speakers a plugged in backChannel is a soundChannel object.
so I have a lot of classes in actionscript 2. But I need to modify my application to use the soundchannel object for audio monitoring. as far as i know this is only in actionscript 3. so it it possible to write one class in AS3 and leave the rest in AS2?
if not is there a conversion tool which can make the process easier?
EDIT: Sorry for the question being reworded, but I am just simplifying the issue. I am not getting accurate values for SoundChannel. position for an external MP3 that is playing.I've tried a variety of audio bitrates and consistently,i am getting a SoundChannel.position that is less (~250 ms) then where the actual audio has played to. As well, the position never equals the duration. It always finishes behind, even when the SOUND_COMPLETE event is generated.
Adobe says any Sound position/duration issues are fixed with the latest Flash Player. I am obviously not getting the same results. I need very accurate position values in order to have a custom draggable timeline and cue points.
I have a Flex(4.6.0) application which creates 3 SoundChannels. I'd like to attach 2 of these channels to a NetStream for publishing, leaving the 3rd SoundChannel only for listening to locally.
The only audio component I can seem to attach to a NetStream is a Microphone, so I could use a Microphone loopback adapter and send ALL sound to the stream, but this would include all channels, windows sounds, sounds from other applications etc.
How do I attach individual soundchannels to a stream, or should I be going about this in a different way?
I'm creating a mute/unmute button.I have it working correctly, except 1 part.I want to make my SoundChannels remove themselves when the SOUND_COMPLETE Event is fired.I'm storing my Sounds and SoundChannels in an array called "soundsPlayingArray".I want to do 1 of 2 things.Either:
1) Have my "unMuteAll" function check to see whether a song is "playing" before unmuting it.
2) Remove the Sound + SoundChannel from array (and make them null) when the SOUND_COMPLETE Event fires.
How can I figure out what the instance name of the SoundChannel that dispatched the SOUND_COMPLETE event is?[code]
I am trying to call a method that pulls several variables depending upon the button clicked.Depending upon the button, it will play a certain sound/song. Below is what i have so far, if anyone could figure out why i get the following error: TypeError: Error #1034: Type Coercion failed: cannot convert "test_Btn12_soundChnl" to flash.media.SoundChannel."test_Btn12" is the button that i happened to click on at that time.
Code: public function buttonClick(e:MouseEvent):void { playSound(MovieClip(e.currentTarget), SoundChannel(String(e.currentTarget.name) +
For some reasons, my soundchannel event.sound_complete is not working. Basically, my class is to import sound into it and to allow use to change their volumes and the speedness of the sound.
This is the tutorial for the speed [URL]
Right now, what I want to do is to auto loop back the song once the song have finished play but I have having troubled doing it.
As I have commented before I am building English teaching apps. I will have music playing in the background, words being pronounced and at times a surprise sentence. All three could sound at the same time at any given point. To build this properly should I use SoundChannel for all of these?
At the moment my code for the music loop is as so. The sound is in the library and exported for AS. Is this code fine or is it better to assign it to the SoundChannel class.
I have some sounds in my library that I want to play in a soundchannel, but how? This is what I have so far:
var music:Sound = new Sound();var channel:SoundChannel = new SoundChannel();var sTransform:SoundTransform = new SoundTransform();var sound:SoundFile1 = new SoundFile1(); // Note: SoundFile1 is a class; in it is my soundfile in the library// music.load(sound); ??channel = music.play();
its for a music sequencer im working on. the class needs an mp3 loaded into the soundchannel to work.I want the soundchannel to be empty and to listen for the sequencer,The visualisation reacts to the sequencer but only when an mp3 is loaded, I just want it to react without an mp3 loaded...
Is there a better way to use the sound channel is AS3?
var mySound:Sound = new Sound(); playButton.addEventListener (MouseEvent.CLICK, myPlayButtonHandler); var myChannel:SoundChannel = new SoundChannel(); function myPlayButtonHandler (e:MouseEvent):void {
I've just started working with sound and as I understand it I primarily need two objects: Sound and SoundChannel. Every call to a Sound.play() method will create a new SoundChannel object. So technically, I could write my code like this:
Code: package { import flash.media.Sound;
[code]....
Will simply create a new SoundChannel object and the first one created by the constructor will be garbage collected? As a side note, it's possible to see Adobe's source files e.g.SoundChannel.as. I'm curious as to how the SoundChannel.stop() method works since it doesn't throw an error or exception even if the audio has already stopped playing.
