Property Detail
audioFileproperty
audioFile:Object

The source audio file. The audio file must be a 16-bit 44.1 kHz stereo mp3.

It can be embedded within your swf/swc, stored as external files, or specified as a FileReference. Typical syntax is as follows.

Embedded mp3 files

		 [Embed(source="ImpossiblyFastSolo.mp3")]
		 private var MUSIC:Class;
		 
		 var extender:AudioStretch = new AudioStretch;
		 extender.audioFile = MUSIC;

mp3 in separate file

		 extender.audioFile = "OceanSurf.mp3";
