In the last tutorial we looked at the design considerations for maximum optimisation. Included in this are some considerations for the usage of sounds and images.
One of the funky aspects of flash is its ability to play sound with its animations but the flip side of the coin is that it takes up space, a lot of it.
Sound uses something called a sample rate. The lower the sample rate the lower the file size (and quality). You can adjust the rate and compression (MP3 is the smallest format for sound) for exported stream and event sounds (see our tutorial on Adding sounds for more info on the difference) in the sound properties box for individuals sounds or in the Publish Settings dialog box for all sounds, by choosing File > Publish Settings. Clicking on Set will give you this dialog box to modify the rate and the compression:
Note: If the movie has no streamed sounds, this setting has no effect.
Note: The sample rate and compression type of sounds acts in the same manner as a .jpg or any other lossy image format. You can go down in quality but you can't go up. The quality of the original file is as good as you will get it (even with increasing the sample rate) without re-recording it.
