How I can remove noise from wav file and play file after noise be remove?

How I can remove noise from wav file and after noise be removed, play the file?

this is my program :

y1=wavread('Doraemon.wav');

Fs=8000;

Fs1 = Fs;

wavplay(y1,Fs1,'sync')

N=length(y1);                    

var = 0.2;

noise_1=var*randn(N,1); 

y_1n=y1 + noise_1;         

wavplay(y_1n,Fs1,'sync')

anyone can help me solve my problem? thanks

You can play the same way that you play the samples with noise added: by using wavplay() with the appropriate array in the first parameter.
