ab: Summary: An automatic content extraction from multimedia files is recently
    being extensively explored. However, an automatic content description
    of musical sounds has not been broadly investigated and still needs an
    intensive research. In this paper, we investigate how to optimize sound
    representation in terms of musical instrument recognition purposes. We
    propose to trace trends in the evolution of values of MPEG-7
    descriptors in time, as well as their combinations. Described process
    is a typical example of KDD application, consisting of data
    preparation, feature extraction and decision model construction.
    Discussion of efficiency of applied classifiers illustrates
    capabilities of possible progress in the optimization of sound
    representation. We believe that further research in this area would
    provide background for an automatic multimedia content description.
