Write a Matlab script that:

Exercise 2 (Convolution and echo): There are several built-in MATLAB sounds, such as chirp, gong, handel, laughter, splat, and train. These sounds are built-in *.mat files that define the sound to appear in a vector named y, and also define the sampling rate for that sound to be in Fs. Pick two sounds and figure out the length of the sounds in seconds. Next, pass the sounds of your choice through the following system: h |1, zeros( 1, dly * Fs), 0.75 where dly is the delay of the echo in seconds. Use sound to play both the input and output for various choice of dly. Explain what you heai.
