A piece of noise music signal is given. It is processed with a sliding average filter to observe the effect of changing the width of sliding window to the sound effect.
(1) a noise signal is read and the time domain waveform and signal spectrum map of the unprocessed noise signal are drawn.
(2) in Matlab, a sliding mean filter is used to process the noise signal, and the image after processing is obtained.
(3) to change the width of the sliding window, to observe the noise after processing and to the effect of the image.
