MATLAB: How to filter a noisy sound with Kalman filter

Question

Hello! I am a begginer in Matlab and I have to filter a noisy sound with a Kalman and a Kalman Like filter. My code is:

load handel.mat

hfile='bugsbunny1'; wavwrite(y, Fs, hfile) clear y Fs

[y, Fs, nbits, readinfo] = wavread(hfile); sound(y, Fs); pause %pt a asculta varianta cu sgomot apasati enter noise=randn(length(y),1)*0.20; sound(y+noise,Fs)

Do you have any idea how can I do this? Thank you a lot! Diana
