An adaptive filter is a filter with non-constant coefficients. The filter coefficients are adjusted based on an criterium which is often defined to optimize the performance of the filter in its ability to estimate an unknown quantity in an input signal. In this lecture, we will limit ourselves to adaptive FIR filters.

square (LMS) adaptive filter of audio signals. It restores the desired audio signal by passing the noisy speech through a FIR filter whose coefficients are estimated by minimizing the mean square error (MSE) between the clean signals [10]. In many applications, LMS adaptive filtering algorithms are widely used, partly be-

Adaptive FIR Filter. A common form of a FIR filter is called an adaptive filter. Adaptive filtering is used in cases where a speech signal must be extracted from a noisy environment. Assume a speech signal is buried in a very noisy environment with many periodic frequency components lying in the same bandwidth as the speech signal.

reduction in the noise content of the speech signal. In [12] an adaptive filter based on LMS algorithm was used to reduce additive white Gaussian noise in audio signal. The authors used a sampling frequency of 8000Hz, filter order of 29, step size parameter of 0.006. The result shows that the algorithm performed effectively.
