Abstract -
Blind Audio Source Separation is a technique to separate out audio signal from various sources recorded by number of microphones placed at different positions. ICA is dominant technique to separate independent components of signals from mixture. Inequality based divergence measure is used to develop a contrast function for source separation using ICA.This work addresses various divergence measures and performance of inequality based divergence measure. Experimental result reflects that Jenson Inequality based convex divergence measure gives better performance than other divergence measures such as Euclidian, Kullback leibler, Cauchy-Schwartz etc. Convex divergence measure for α= -1 gives 20-25% better and faster convergence than other and can be adopted for audio source separation by incorporating Independent component analysis.
