Abstract: A method of creating a template data structure for a media effect involving a media data item to be presented during a presentation of the media effect is disclosed. The method comprises: defining a time stamp for an event of the template data structure, the time stamp comprising a relative time stamp component indicating a time span within the presentation of the media data item as a portion of a duration of the presentation, and an absolute time offset component indicating a time span independent from the duration of the presentation. A related method defines the processing of a media data item to be presented during a presentation, the related method using the above mentioned time stamps to determine a temporal position of an event to occur during the presentation. A corresponding template creator, a media data processor, and a computer readable medium are also disclosed.

Abstract: An audio signal generator for generating an audio signal (20) having a selected length (14) comprises a database interface (10) for accessing a database (12) having information on a plurality of different predefined sequences of audio samples, the information for a sequence comprising an order (12c) of audio samples in the sequence and a duration (12b) of the sequence. The audio signal generator additionally comprises a processor (14) for constructing the audio signal (20) by serially connecting a plurality of sequences using the information on the duration (12b) of each sequence in accordance with the construction algorithm to obtain the audio signal (20) having the selected length (15).
