Abstract
A method and apparatus for generating and observing a transition between a first and second sequence of information. The invention is practiced on a computer controlled display system and a computer controlled sound generation system. The method includes providing the first stream and the second stream of information to the computer system; creating a template for modifying an audio signal during a transition from the first stream of information to the second stream of information; specifying the duration of the transition and specifying at least a portion of the first stream and a portion of the second stream for the transition; creating an audio transition using the audio template for modifying an audio signal and using the portion of the first stream and the portion of second stream. Another aspect of the invention includes a method for controlling the rate of transistion from the first stream of digital information to the second stream of digital information which method includes: providing the first stream of information and second stream of information to the computer system; providing a rate transition template for specifying the rate of transition during the transistion; specifying the duration of the transistion and at least a portion of the first stream and the second stream for the transition; creating the transition using the rate template and the portions of the first and second streams, wherein the rate transition template includes a visual representation of the rate of transition over the duration of the transition.
