In this paper we employ
information theoretic
algo rithms, previously used for separating instantaneous mixtures of sources, for separating convolved mix tures in the frequency domain. It is observed that convolved mixing in the
time domain
corresponds to instantaneous mixing in the frequency domain. Such mixing can be inverted using simpler and more robust algorithms than the ones recently developed. Advantages of this approach are improved efficiency and better convergence features.
