DoReMedia separates these instruments into their own audio layers allowing for individual volume control. Manipulating the volume of these layers gives the developer complete control over the dynamics of the soundtrack as a whole. Like chunks , each layer is only downloaded once then reused repeatedly. Instrument layers can be played in unison to increase tension and excitement, or they can be played individually to change the mood to match the visual components of the movie. The result is a highly customizable soundtrack with significantly reduced file sizes.
Layers offer complete control over the soundtrack, but are more involved to use than chunks .
For the ultimate sound experience, both chunks and layers can be used together to create the perfect soundtrack. In traditional media such as Television, the message is delivered in an exact, linear manner. Conversely, rich media invites user interaction and decision making. Because of this, Sound Families provide event sounds that are harmoniously tailored to the individual soundtrack giving a fully integrated experience. DoReMedia event sounds are extracted from the individual tracks of the original recording.
