PathOriginal = fullfile('C:\Users\Documents\MATLAB', 'AUD-20150716-WA0032.wav');
[y, Fs, n] = wavread(PathOriginal);
b=1;
a=0.1;
a=[1 -0.1];
x(n)=y(n)-0.1*y(n-1);
y=filter(b,a,x)
what command should i use to hear the sound before and after applying filter??

I do not see any connection to the tags "Matlab compiler" or "differential equations". Please use tags, which helps to identify the nature of the question.

See: audioplayer
PathOriginal = fullfile('C:\Users\Documents\MATLAB', 'AUD-20150716-WA0032.wav');
[y, Fs, n] = wavread(PathOriginal);
b=1;
% a=0.1; Useless, omit this line!
a=[1 -0.1];
% ??? x(n) = y(n)-0.1*y(n-1);
yFiltered = filter(b,a,y);
audioplayer(y, FS);
audioplayer(yFiltered, FS);
