Abstract
Time scaling is a technique used to modify media-object presentation duration. This paper proposes an audio time-scaling algorithm focused on supporting applications that need: to maintain the original data format for storage or immediate presentation on any legacy audio player; to perform linear time scaling in real time, allowing the adjustment factor to vary along the audio presentation; and to perform time mark-up maintenance, that is, to compute new time values for original marked audio time instants. The proposed algorithm is appropriate for those applications that do not need a great adjustment factor variation. The integration with content rendering tools is presented in the paper and also an example of using these tools in a hypermedia presentation formatter.
