Design an interface using MATLAB APPDESIGNER. Let the interface consist of the following components:

a$.$ File reading buton

b$.$ Informative labels

c$.$ Displaying windows $($separate sub$-$windows for processed data$)$

$2.$ Find a dataset related with human sound signals from internet or make a record by using Audacity.

$3.$ With the help of this interface:

a$.$ Read one of data form sound files $($consider the first $5-10$ seconds of data$)$

b$.$ Display the original sound data in a window

c$.$ Add random Gaussian noise to the sound signal

d$.$ Display FFT of the original and noise added sound signals in separate windows

e$.$ Design a digital FIR filter to filter out the undesired signal

f$.$ Filter the noisy signal in discrete time domain.

g$.$ Display filtered sound signals in separate windows
