FAST PLEASE
You are asked to design and create a MATLAB GUI to test DPCM
with audio signals.
The audio signal should be recorded by the user, all needed
parameters should be entered by the user using the graphical user
interface.
All needed parameters for DPCM simulation should be entered by
the user using the graphical user interface.
The recorded and the reconstructed signals should be
sketches.
At the end of the simulation, the user can play the original and
the reconstructed audio.
The mean squared error should be shown as well.
