How to Import Audio to Flash Library
Importing audio and placing it on the timeline is a two part process. It is best to create your audio file and save it in your project's Assets folder. Make sure to save your fla file before importing to create a link to the original. Once the file is imported, simply select a keyframe and drag the file from Library to the stage.
In a new flash document, add a new layer. Name the upper layer Actions and the lower layer Audio.
Choose File > Import > Import to Library.
Navigate to your mp3 or aif file and choose Import.
Open the Library (Window > Library).
Select frame one of your Audio layer and drag the audio file in the Library to the stage.
Publish your movie by pressing Cmd/Return (PC - Ctrl/Enter). The audio starts playing and plays only once.
AIF or MP3
Using this method you can import either .aif files (Mac) or mp3 files (Mac or PC).
Prior to importing audio, it is best to verify the project audio settings. To view and change the default audio settings, choose File > Publish Settings. Click the Flash tab, then click the Set.. button next to Audio Stream.
