In this paper, we are interested in blind source separation from instantaneous mixtures of audio signals. Using the sparsity property of audio signals, we propose an iterative method that relies on a relative gradient technique which minimizes a contrast function based on the `p norm. This norm is considered as a good sparsity measure. The simulations show that the proposed method outperforms other methods based on source independency.
