Question

Q1) Record your voice introducing yourself (Name, Student ID Programme. Affiliation,
etc.);
Read the recorded sound file using the appropriate Octave command. Determine is the sampling
rate of your recording? To view the signal, plot the recorded signal in the time domain with
sufficient information added to the graph.

Q2) Write the Octave data for the audio back to another audio file on your desktop, using Octave
audiowrite command with 40% of the sampling rate found in (Q1). Listen to the new voice file
then write your conclusions. Add Octave statement to overcome the issues caused by reducing
the sampling rate

Q3) Apply the FFT (Fast Fourier Transform) algorithm to find DFT, to your audio script. Plot
them in the frequency domain, explain the differences plot from the plot of Q1, the benefits of
the DFT, and the meaning of it.
