This paper proposes an algorithm for removing the noise from the audio signal. Filtering is achieved through recording the pattern of noise signal. In order to validate our algorithm, we have implementation in MATLAB 7.0. We investigated the effect of proposed algorithm on human voice and compared the results with the existing related work, most of which employ simple algorithm and effect the voice signal. The results show that the proposed algorithm makes efficient use of Voice over the IP communication with less noise in comparison to similar existing algorithm.
