| Abstract(in English) | This report presents a method to separate the audio sources from their single mixture. The system is based on deriving some independent basis vectors from the mixture spectrogram and clustering them to produce the individual source subspaces. Principal component analysis (PCA) is used to reduce the dimension of mixture spectrogram producing some basis vectors. A data-adaptive decisive factor is proposed for the proper selection of the basis vectors. Independent component analysis (ICA) is employed to make the selected basis vectors independent from each other in their own domain. Kullback-Leibler divergence based k-means clustering algorithm is introduced to grouping the independent basis vectors into given number of sources. The satisfactory result of two-source mixture separation motivates to use this system for real world single mixture audio source separation. |
