The Karplus-Strong Algorithm in MATLAB

%Code:-

clc

clear all

close all

x=rand(1,100);

x=[x zeros(1,5000)];

num=[1];

den=[1 zeros(1,99) -0.5 -0.5];

y=filter(num,den,x);

sound(y,44100)

You can change the random sequence range and according to that change the no. of zeros in denominator of the filter and play ---

clc

clear all

close all

x=rand(1,500);

x=[x zeros(1,10000)];

num=[1];

den=[1 zeros(1,499) -0.5 -0.5];

y=filter(num,den,x);

sound(y,44100)
