In this tutorial, we are going to add a music file and modify it. Have a music file ready somewhere on your hardrive, that is all we will be needing.
1. Open a new document and Choose
File > Import > Import to Stage
2. Next open the flash library (Ctrl+L) and drag the music track icon anywhere on the stage.
3. Next, take a look at the timeline. There should be just one frame with a line across the middle of it, this indicates that there is a sound on that frame. What you want to do is
select that frame, it should highlight black when selected.
4. Press (Ctrl+F3) to bring up your properties panel. Press "Edit" to get inside the track
5. Click on the (Minus Maginfying Glass) to view the whole track. It is easier to work with a track if you can see the whole thing obviously.
6. Click on the line to create points in the track to create fade in and fade outs. You can be as creative as you want to using points. Test your track by pressing play. You can even shorten up a track by dragging sliders, view image below

7. You can always go with presets.

Finally, when it is time to export, we recommend these settings for both quick loading and good sound.

There you have it. :D
