The MDTools application will let us to generate MPEG-7 XML files with multimedia information and its associated metadata. The main tools that will integrate are:
Timeline/segment edition: in that edition mode, segments of multimedia content can be edited, synchronised and re-segmented by hand if needed. We can associate media information to the segments (audio, video, score files, etc.), create links between them, and add MPEG-7 metadata (descriptors, semantics, etc.). All that metadata can be used to search & retrieval purpouses.
Classifications: that will be a hierarchical view to create taxonomies. We can link that with the information in the segments. That can be used, for instance, to search the segments that have violins playing.
Audio analysis and segmentation: a set of tools will be added to make audio analysis of MPEG-7 Audio LLDs and HLDs (Low/High Level Descriptors). Interesting uses of that tools are automatic segmentation of the content, melody recognition or sound classification. Some of these tools will be useful to generate the analysis needed for the OperaTutor application and also for audio-score synchronization.
