Hour 10. Including Sound in Animations > Controlling Quality and File Size

Controlling Quality and File Size

Now that you know how to incorporate sound in a movie, it's time to talk about optimizing it for export. A direct relationship exists between quality and file size. If you want the best-quality sound, the file size will grow. Conversely, small file size means lower sound quality. This is just a fact. You ultimately need to make a decision about how to balance this tradeoff. Is a high-quality sound important enough to make your audience sit through an extended download time? Is a speedy download worth the sacrifice in quality? You should be very deliberate in your decision-making process to end up with the best compromise possible. While exploring this topic further, we'll first cover some digital audio fundamentals, and then you'll learn how to apply this knowledge to Flash's compression settings.

Digital Audio Fundamentals

Earlier this hour I suggested there were two sensible ways to use audio in Flash. You can start by either importing as high-quality audio file as possible (.wav or .aif) and let Flash compress it when you publish or importing an MP3 which, by definition, is already compressed.
