Using Component Audio (Chunks) and SyncTracks to Create Compelling Soundtracks with Small File Sizes - Page 3
Why Use Chunks?
Chunks can be implemented in a few different ways. They can be implemented almost exactly the same way as layers, triggering 2 or more chunks on the same keyframe, and then using volume envelopes to mute and unmute each piece of audio to create musical dynamics. Or, Chunks can be used in a linear fashion and inserted at various points across the timeline, using Flash to "shuffle" the playing order to build a unique musical arrangement. Using chunks frees you from the 8 part limitation of Layers, and allows for more musical variation. Layers give you more permutations, but less dynamic range. Think of it this way: Layers put together make up a groove. Chunks put together make up a song.
As described in Tutorial 1, by using layers and volume envelopes, we can avoid the need to force frame rates (see below). But Layers can be limiting. You can only have up to 8 layers at a time (muted or unmuted). You can only have up to 8 envelopes per layer, which can become an limiting issue with longer or more complex soundtracks. And layers can be difficult to modify - if your movie structure changes, or you want to change the arrangement of your layered soundtrack, you have to progressively edit every layer's envelope many times. In these situations, Chunks can be more scalable and simpler to modify.
Chunks are like sound Legos. You simply "attach" one clip to the next to construct your own musical arrangement. Similarly to layers, after you use a chunk for the first time, it's "free". The file is stored in cache and can be re-used later in your movie without adding to file size. And you can associate specific pages, scenes, buttons and user actions with specific chunks, making your soundtrack truly interactive.
