This paper presents a delayed instantaneous demixer (DID) for speech signal separation from real recordings. Based on the fact that the original signals are colored and mutually uncorrelated, a simple algorithm is derived to estimate the parameters of the demixer. This algorithm consists of two parts: a grid searching method to estimate time delays and an alternating projection method to estimate gain coefficients. Experimental result demonstrates the performance of the model and the algorithm.
