| When deciding on the sound effects and background music you will be adding to your FlashR storybook app, you want to remember that the size of the file is very important. Mobile devices have a limited amount of CPU and memory. Each sound file that you use in your app will increase the size of the project file.|
Most mobile devices can play .mp3 files easily, so if your stock of sound files is as old as mine and still in the .wav format, you will probably want to convert the .wav file to .mp3 format. This can be easily done in Adobe SoundboothR. While you have the file open in Soundbooth, you might want to adjust the length and volume. Ask yourself if you can remove any part of the sound and still have the same effect. It's easy to "crop" the ends off a sound file in Soundbooth. Secondly, evaluating the volume of the sound is especially important for background music and sound effects when you are also using a narration. You will want the narration to be loader than the sound effects and background music.
Our example will be a simple jingle sound file in the .wav format. We will trim the ends to shorten the length and then lower the volume. Then we will convert it to the .mp3 format.
