A mono audio signal is stored in MATLAB as a vector, while a stereo audio signal is stroed as a two-column matrix. The elements of the vector (or the matrix) are sampled and quantized data points. The data points range from -1 to 1 if the data type is double, and they range from 0 to 255 if the type is uint8. Other data types can be used, but most commenly used data types are double and uint8, for audio signals proccced in MATLAB. Download the four audio files from Beachboard. Then, use the MATLAB program below to listen to the bass audio. bass # audioread('bass.war'); or : bass audioread('C:\Users\ Ibrahim A\Desktop\EE386 (DSP)\Labs\Lab2lbass . war'); 9 # 44100; bass seq bass (fs 10:fs 20) s sampling freq segment from 10th sec t. 20th 5ec sound (bass_seq, fa) i s use clear sound to stop playing bass-sound audioplayer (bass-seg, fa) ; play (bass sound) s use 'stop (bass sound)" to stop playing plot (bass seq) (A) Is bass a mono audio signal or is it a stereo audio signal? Explain. In the Workspace window, double click eg, and guitar_seq all from the 10% second gnals (from part B) together into one audio and why? Explain your answers on bass. What do the numbers that you see represent? (B) Modify the MATLAB code to plot bass seq, drums s to the 20th second. Use MATLAB function subplot and make sure to label both axes and include titles. (C) Modify the code to combine the three segments of the three si play it. Now, double the sampling frequency and play it again. What changed and why? Cut the original sampling frequency by half then play the audio one last time. What changed and in terms of up-sampling and down- sampling
