EE434 - Project 1 Sound Processing Part III (Echo Generation) (a) Write a MATLAB rn-file to simulate an echo described by the following equation: y(n) z(n) + ax(n-D Let a = 0.9 and D is a number of samples equivalent to a delay of 2 seconds. Test your code using sound editing wav file. What is the effect of increasing or decreasing the value of a? What is the effect of increasing or decreasing the value of D? (b) Repeat part (@) with y(n) = x(n) + a, x(n - D.) + a, x(n-1) + a, x(n- D) where a =0.9, az = aš, az -a, and D, = 2D, D = 3D, where D, is a number of samples equivalent to a delay of (1/3) second. Test your code using the same sound editing wav file. What do the constants az, az, and a, represent? What are the effects of increasing or decreasing their values? Justify your answer using MATLAB. What do the constants Di, Dy, and Dy represent? What are the effects of increasing or decreasing their values? Justify your answer using MATLAB.
