Property Detail

bufferTime | property

`public var bufferTime:Number = 1000`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The SoundEffect class uses an internal Sound object to control the MP3 file. This property specifies the minimum number of milliseconds worth of sound data to hold in the Sound object's buffer. The Sound object waits until it has at least this much data before beginning playback, and before resuming playback after a network stall.

The default value is `1000`.

isLoading | property |

`isLoading:Boolean` [read-only]

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

This property is `true` if the MP3 has been loaded.

Implementation
`public function get isLoading():Boolean`

loops | property |

`public var loops:int = 0`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The number of times to play the sound in a loop, where a value of 0 means play the effect once, a value of 1 means play the effect twice, and so on. If you repeat the MP3 file, it still uses the setting of the `useDuration` property to determine the playback time.

The `duration` property takes precedence over this property. If the effect duration is not long enough to play the sound at least once, the sound does not loop.

The default value is `0`.

panEasingFunction | property |

`public var panEasingFunction:Function`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The easing function for the pan effect. This function is used to interpolate between the values of `panFrom` and `panTo`.

panFrom | property |

`public var panFrom:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Initial pan of the Sound object. The value can range from -1.0 to 1.0, where -1.0 uses only the left channel, 1.0 uses only the right channel, and 0.0 balances the sound evenly between the two channels.

The default value is `0`.

panTo | property |

`public var panTo:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Final pan of the Sound object. The value can range from -1.0 to 1.0, where -1.0 uses only the left channel, 1.0 uses only the right channel, and 0.0 balances the sound evenly between the two channels.

The default value is `0`.

sound | property |

`public var sound:Sound`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Reference to the internal Sound object. The SoundEffect uses this instance to play the MP3 file.

soundChannel | property |

`soundChannel:SoundChannel` [read-only]

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The SoundChannel object that the MP3 file has been loaded into.

Implementation
`public function get soundChannel():SoundChannel`

source | property |

`source:Object`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The URL or class of the MP3 file to play. If you have already embedded the MP3 file, using the `Embed` keyword, you can pass the Class object of the MP3 file to the `source` property. Otherwise, specify the full URL to the MP3 file.

Implementation
`public function get source():Object`
`public function set source(value:Object):void`

startTime | property |

`public var startTime:Number = 0`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The initial position in the MP3 file, in milliseconds, at which playback should start.

The default value is `0`.

useDuration | property |

`public var useDuration:Boolean = true`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

If `true`, stop the effect after the time specified by the `duration` property has elapsed. If `false`, stop the effect after the MP3 finishes playing or looping.

The default value is `true`.

volumeEasingFunction | property |

`public var volumeEasingFunction:Function`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The easing function for the volume effect. Use this function to interpolate between the values of `volumeFrom` and `volumeTo`.

volumeFrom | property |

`public var volumeFrom:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Initial volume of the Sound object. Value can range from 0.0 to 1.0.

The default value is `1.0`.

volumeTo | property |

`public var volumeTo:Number`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Final volume of the Sound object. Value can range from 0.0 to 1.0.

The default value is `1.0`.
