| Abstract(in English) | Extracting only the essential sound attributes from sounds is one of the fundamental issues of music information retrieval. This paper shows the efficiency of the use of linear discriminant analysis for instrument feature extraction by analyzing the algorithm geometrically. For monophonic music instrument identification, various feature extraction and selection methods have been proposed. Although raw power spectra have enough information for accurate instrument identification, their dimensionality is too high and redundant. As such a dimensionality reduction method, linear discriminant analysis (LDA) is applied to the preprocessed power spectra by principal component analysis (PCA). |
