AbstractIn this workshop we will demonstrate three applications for content-based retrieval and transformations of audio recordings. They illustrate diverse aspects of a common framework for music content description and structuring implemented using the MPEG-7 standard. MPEG-7 descriptions can be generated either manually or automatically and are stored in an XML database. Retrieval services are implemented in the database. A set of musical transformations are defined directly at the level of musically meaningful MPEG-7 descriptors and are automatically mapped onto low-level audio signal transformations. Topics included in the presentation are (1) Description generation procedure, manual annotation of editorial description the MDTools, automatic description of audio recordings, the SPOffline; (2) Retrieval functionalities, local retrieval SPOffline, remote retrieval web-based retrieval; and (3) Transformation utilities the SPOffline.
