FlashAudioPlugin Class

Extends AbstractPlugin
Defined in: FlashAudioPlugin:41
Module: SoundJS

Play sounds using a Flash instance. This plugin is not used by default, and must be registered manually in Sound using the registerPlugins method. This plugin is recommended to be included if sound support is required in older browsers such as IE8.

This plugin requires FlashAudioPlugin.swf and swfObject.js, which is compiled into the minified FlashAudioPlugin-X.X.X.min.js file. You must ensure that swfPath is set when using this plugin, so that the script can find the swf.

Example

 createjs.FlashAudioPlugin.swfPath = "../src/soundjs/flashaudio";
 createjs.Sound.registerPlugins([createjs.WebAudioPlugin, createjs.HTMLAudioPlugin, createjs.FlashAudioPlugin]);
 // Adds FlashAudioPlugin as a fallback if WebAudio and HTMLAudio do not work.

Note that the SWF is embedded into a container DIV (with an id and classname of "SoundJSFlashContainer"), and will have an id of "flashAudioContainer". The container DIV is positioned 1 pixel off-screen to the left to avoid showing the 1x1 pixel white square.

Known Browser and OS issues for Flash Audio

All browsers

  • There can be a delay in flash player starting playback of audio. This has been most noticeable in Firefox. Unfortunely this is an issue with the flash player and the browser and therefore cannot be addressed by SoundJS.

)
protected

Handles internal preload completion.

Parameters:

_handlePreloadError

(
  • event

_updateVolume

() Boolean protected

Inherited from AbstractPlugin but overwritten in _updateVolume:317

Available since 0.4.0

Returns:

create

  • src
  • startTime
  • duration
)
AbstractSoundInstance

Inherited from AbstractPlugin: create:213

Create a sound instance. If the sound has not been preloaded, it is internally preloaded here.

Parameters:

  • src String

    The sound source to use.

  • startTime Number

    Audio sprite property used to apply an offset, in milliseconds.

  • duration Number

    Audio sprite property used to set the time the clip plays for, in milliseconds.

Returns:

AbstractSoundInstance :

A sound instance for playback and control.

getVolume

() Number

Inherited from AbstractPlugin: getVolume:252

Get the master volume of the plugin, which affects all SoundInstances.

Returns:

Number :

The volume level, between 0 and 1.

isPreloadComplete

(
  • src
)
Boolean

Checks if preloading has finished for a specific source.

Parameters:

  • src String

    The sound URI to load.

Returns:

isPreloadStarted

(
  • src
)
Boolean

Checks if preloading has started for a specific source. If the source is found, we can assume it is loading, or has already finished loading.

Parameters:

  • src String

    The sound URI to check.

Returns:

isSupported

() Boolean static

Defined in isSupported:224

Determine if the plugin can be used in the current browser/OS.

Returns:

Boolean :

If the plugin can be initialized.

preload

(
  • loader
)

Inherited from AbstractPlugin: preload:154

Internally preload a sound.

Parameters:

  • loader Loader

    The sound URI to load.

register

(
  • loadItem
)
Object

Inherited from AbstractPlugin: register:132

Pre-register a sound for preloading and setup. This is called by Sound. Note all plugins provide a Loader instance, which PreloadJS can use to assist with preloading.

Parameters:

  • loadItem String

    An Object containing the source of the audio Note that not every plugin will manage this value.

Returns:

Object :

A result object, containing a "tag" for preloading purposes.

removeAllSounds

(
  • src
)

Remove all sounds added using WebAudioPlugin/register. Note this does not cancel a preload.

Parameters:

  • src String

    The sound URI to unload.

removeSound

(
  • src
)

Remove a sound added using WebAudioPlugin/register. Note this does not cancel a preload.

Parameters:

  • src String

    The sound URI to unload.

setMute

(
  • value
)
Boolean

Inherited from AbstractPlugin: setMute:261

Mute all sounds via the plugin.

Parameters:

  • value Boolean

    If all sound should be muted or not. Note that plugin-level muting just looks up the mute value of Sound muted, so this property is not used here.

Returns:

Boolean :

If the mute call succeeds.

setVolume

(
  • value
)
Boolean

Inherited from AbstractPlugin: setVolume:239

Set the master volume of the plugin, which affects all SoundInstances.

Parameters:

  • value Number

    The volume to set, between 0 and 1.

Returns:

Boolean :

If the plugin processes the setVolume call (true). The Sound class will affect all the instances manually otherwise.
