Question 1: Audio processing in Matlab Find an audio clip (.wav file, or other audio format) and load the audio clip into the Matlab. You can use the audioread function in Matlab to do this. Type help audioread at the Matlab prompt for more information. Achieve the following: • Learn and demonstrate how to play the audio clip within Matlab. • Find the discrete Fourier transform (DFT) of the audio clip using the fft function in Matlab. • Plot the magnitude and phase of the DFT of the audio. • Lets call your Matlab variable containing the audio clip x(n) for index n. Define a lineae time-invariant system as y(n) = x(n) +0.5r(n-1) +0.7.r(n − 2) and implement it in an M-code. • Play the sound of the LTI system output y(n) using the same method you used for playing the input clip.
