Hi everybody,
I have a problem using your AudioAS framework. When i play a sound, the iPhone requires the microphone. Do you know how to solve this bug? Thank you.

The SoundInstance.stop function resets the pauseTime and stops the current and old channels, which successfully stops the audio. However, isPlaying does not reflect that since all of it's conditions can still be true.

This only really presents itself with a looping sound, since onSoundComplete seems to adequately clean up the current sound channel.

I think stopChannel needs to clear the current channel and possibly clean up the list of old channels in addition to simply stopping the current channel. But, I'm unsure of the affect of this on other scenarios.

Hi guys,

When I add a new sound, the masterVolume doesn't seem to be initialized for the new SoundInstance.

How to reproduce :

private var sound:Sound;
private var i:int = 0;

public function testMasterVolume():void
{
    sound = ResourcesController.getInstance().getSound("sound_jump");
    var myTimer:Timer = new Timer(1000, 3);
    myTimer.addEventListener(TimerEvent.TIMER, onTime);
    myTimer.start();
}

private function onTime(event:TimerEvent):void 
{
    switch(i)
    {
        case 0:
            SoundAS.addSound("mySound_1", sound);
            SoundAS.masterVolume = 1.0;
            SoundAS.playFx("mySound_1"); // ok
        break;
        case 1:
            SoundAS.masterVolume = 0.5;
            SoundAS.addSound("mySound_2", sound);
            SoundAS.playFx("mySound_2"); // WRONG : still use masterVolume at 1.0
        break;
        case 2:
            SoundAS.masterVolume = 0.5; // update all SoundInstance
            SoundAS.playFx("mySound_2"); // ok
        break;
    }

    ++i;
}

Im doing update on enter frame that checks for isPlaying. For the first 3 frames its false even when sound is playing, then it is true for few another frames, and once again after sound loops it gets "false".

I just posted about this on the official starling game engine forum here: http://forum.starling-framework.org/topic/does-anyone-else-use-tree-fortresss-soundas-sound-manager#post-89464 but I'll go ahead and summarize here:

I think I've found a memory leak. If you do something like the following:

SoundAS.play('my_sound').soundCompleted.addOnce(function(si:SoundInstance){
trace('Hello, my name is Mr. Leaky McLeakerson! I'm here to eat your memory.');
}
SoundAS.stopAll();

Using .stopAll() will not remove the callback you just added. The closure hangs around in memory along which whichever class originally added that callback. (In my case, it was the play screen, so needless to say things got out of hand quite quickly.)

I won't rule out that maybe I'm just misunderstanding how SoundAS callbacks are supposed to work. If I'm not understanding the proper way to stop them, I'd love it if you could fill me in.

(Thanks a million for the library BTW, it's been great- save for this one hiccup!)

Hi. I read your comments about adding the enableSeamlessLoops flag, and I see that you are aware it is perhaps buggy, but I thought I'd report this in case it is unknown.

My issue is that when I use the playLoop function, the sound loops back to the supplied starting position, not back to the start of the sound, as seems like the expected behaviour. By turning off the enableSeamlessLoops flag it worked fine. It actually only caught me out because the flag is true by default.

So, this loops back to midway through:

SoundAS.playLoop(  'some_music', 1, resumePosition, true );

...and this loops back to the beginning, as expected:

SoundAS.playLoop(  'some_music', 1, resumePosition, false);

Thanks :)

In my game I have the following scenario:

Multiple instances of an enemy all have the same looping sound started via:

_loopingSound = SoundManager.play("howl", 1, 0, 999, true);

(_loopingSound is a private SoundInstance contained inside each enemy instance.)

Now let's say one of the enemies is killed and I want to stop his sound:

_loopingSound.stop();

This causes ALL the other enemies looping sounds to suddenly stop.

Ideally by stopping one enemy's sound the others would still keep playing.

Am I missing something, or is this behaviour not currently supported?

If so it would be a great option to have.

Is there a reason why you don't support panning?

it should be

sound.volume = value;

Hi guys.

I'm just playing around with your awesome SoundAS framework, but I have some trouble with using it on the iPad.

Sounds load and play correctly when running the Air application on the desktop (actually when testing in the Flash SDK), but as soon as I port it to the iPad, all sounds are gone.
Is this something you can help me solve?

Thanks in advance guys. :)

Assume you have 2 instances of the same sound

var si_1:SoundInstance = SoundAS.getSound("somesfx",true);
var si_2:SoundInstance = SoundAS.getSound("somesfx",true);

now if both sounds are playing and you wanted to fade out one of them the SoundInstance.fadeTo method doesn't actually fade that instance .. it calls the SoundManager.addTween with the "type" of sound .. many instances are playing having the same type! .. in this case the addTween method call the getSound() method that throws a stack overflow error .

When pausing an already completed sound instance (or using pauseAll as I am in this case), a TypeError #1009 (Cannot access a property or method of a null object reference) is triggered after attempting to execute resume (or resumeAll) on that instance.

TypeError:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at treefortress.sound::SoundInstance/play()[F:\development_libs\SoundAS\lib\src\treefortress\sound\SoundInstance.as:98]

This SoundInstance has actually completed. The startTime and pauseTime values equal the length of the sound property, and the channel property has been set to null.

Yet, because resume only checks for isPaused or forceStart, and isPaused only checks the pauseTime value, which is greater than 0, it attempts to resume the sound. Which fails.

Presumably, it fails because this line in the play method is not returning a value for the channel when the startTime = sound.length.

channel = sound.play(startTime, 0);

This invalid channel variable is what is then being accessed on the line indicated in the error message.

Possible solutions are either to include a check for a valid channel variable in the isPaused property and/or reset the pauseTime variable in onSoundComplete.

If a group is created using

SoundAS.group("name");

and you try to play a sound that is lot loaded, the getSound() function in SoundManager.as goes into infinite recursion on following lines:

//If instance was not found, check out parent manager;
if(!si && parent){ si = parent.getSound(type); }

//Still not found, check the children.
if(!si && groups){
    for(var i:int = groups.length; i--;){
        si = groups[i].getSound(type);
        if(si){ break; }
    }
}

having a group, causes the check in children to run, which in turn checks the parent, which in turn again the children - and lo infinite recursion!

An easy solution would be to not check the parent for the sound.
If I am requesting a sound in a group I surely don't want it from another group or the parent.

Hi, noobs here!

question is... How to check that sound is already load?
so i can just play if sound already load...
far as i try is

var si:SoundInstance = SoundAS.getSound("somesound");

but at present it will throw error if it not exist, i did expected null for first load then call SoundAS.loadSound if si is null e.g.

if(!si)
    SoundAS.loadSound("somesound.mp3", "somesound");

and if i load sound via SoundAS.loadSound again without check for existing
SoundAS.loadCompleted is seem to be never fire for second load same url and type.

btw, i don't think it's a good idea to try catch there. "null for non exist SoundAS.getSound" should be better there.

Thanks

Hi,

I have found that when calling fadeTo() to fade out a SoundInstance with a volume of less than 1.0, the volume of that instance jumps up to 1.0 before fading back down to zero.

_currentSoundInstance.volume = _globalVolume; // 0.3 - just making sure it is set
_currentSoundInstance.fadeTo( 0, fadeTime, true );

If I step through the SoundAS code, the volume jumps in SoundTween, at line 45:

sound.volume = easeOutQuad(t - startTime, startVolume, endVolume - startVolume, duration);

The volume gets set to 1.0 regardless of the startVolume. (Which in this case is 0.3).

Thanks.

This is a handy utility class! One nice feature would be a group.playRandom() function. For example, I may have a group of punch "swooshes" or VO queues that get played when the hero accomplishes something awesome, but I don't want to play the exact same sound every time. It would be nice to be able to create a group of sounds, and then just .playRandom() on that group.

Thanks!

I'm confused on how I could load a Soundfile from an SWC library.

I started of my using:
private var SoundAS:SoundManager;

and thought I could then add the MP3 from my SWC like so:
SoundAS.addSound("found", mp3found);

But that didnt worked. Any tips?

SoundAS cannot play loops seamlessly, even the loop sound is gap-less and embedded inside flash ide.. which means it can be played back in seamless loop by using sound.play(0, int.MAX_VALUE)

hopefully it can be fixed.

Code:

SoundAS.addSound("sample",new samplesound());
var snd:SoundInstance = SoundAS.getSound("sample",false);
trace('getSound("sample",false).type='+snd.type);
var snd:SoundInstance = SoundAS.getSound("sample",true);
trace('getSound("sample",true).type='+snd.type);

Output:
getSound("sample",false).type=sample
getSound("sample",true).type=null

Presumably, the "si = si.clone()" is failing.

A quick review turns up this likely culprit:

public function clone():SoundInstance {
var si:SoundInstance = new SoundInstance(sound);
return si;
}

The new instance is not being passed the existing type parameter in it's constructor, thus resulting in a null value.

I'm trying to use fadeMasterTo on groups, like this:
SoundAS.group(Configuration.musicGroup).fadeMasterTo(0);
but it doesn't change masterVolume value. Setter works properly.
SoundAS.group(Configuration.musicGroup).masterVolume = 0;
Can you confirm this?

Thanks

I'm waiting on a sound to complete with soundCompleted firing a function.

However, if the sound fails to load, that function never gets called.

Is there a way to fire the function even if the sound fails to load, so at least the rest of the program can continue on its merry way?

Cheers

I do this:

_scenarioSounds.play("audioStart").soundCompleted.addOnce(startSoundComplete);

and in the next function I try to tidy up and release the memory used by the sound:

private function startSoundComplete(si:SoundInstance):void
{
trace("startSound complete");
si.soundCompleted.removeAll();

                    //cleanup methods I tried.

        //1: _scenarioSounds.removeSound(si.type);
        //2: si.destroy();
    }

Both fail, I presume because of the last line in the destroy function:

fade.end(false);

Since fade is already null this won't work like it's supposed to.
