Abstract :
This paper is devoted to show the possibilities for optimally steering a Binaural Negative Filter using two techniques based in the optimisation of a Cost Function. These filters may be used in source separation, speaker tracking, or speech enhancement with application in Robust Speech Recognition, Domotic Control, or Video-Conferencing, among other fields.
