| In 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. |
