If we listen to the original wave file, we can hear the noise. Using MATLAB, we can remove the noise by moving average filter. Additionally, we will find the impairing frequency and the order of Moving Average filter removing the impairing noise.

※ Moving Average Filter
Moving Average Filter is a filter averaging some consecutive values of the signal. If we average (N+1) values, then we can call the filter ‘(N+1) point Moving average filter’, or, ‘ Nth Order Moving Average Filter.
