A significant fraction of mobile users in the rural developing world use low-end mobile devices and have restricted data connectivity services due to a variety of economic factors. These devices have restricted capabilities with voice and SMS remaining the primary communication channels. The penetration of mobile information services in rural areas has(More)

In this paper classification of musical instruments is done using higher order spectra using different hierarchical taxonomies. Since last three decades higher order statistics techniques have been developed but until not applied to musical instrument classification. Present work uses higher order spectra to detect and quantify non gaussianity and(More)
Higher order statistics in signal processing plays very important role to extract additional information from signals than second order statistics. This paper used higher order spectra to obtain phase entropy, non-linearity and non-gaussianity statistics from musical instrument signals to classify them hierarchically with two different taxonomies. 19(More)
