Abstract :
This paper shows how the Ratchet fast affine projection (FAP) adaptation algorithm is used in place of a much more sophisticated algorithm in a recently published voice separation scheme. This reduces the system complexity to be comparable to that of a one using the NLMS adaptive filters. Simulations with real room recordings show that the scheme based on Ratchet FAP converges fast, provides a good separation of the sources, and is quite immune to the ambient noise. Audio demos will be given when this paper is presented.
