% create a matrix , the size of x for efficient and speedier operation
y = zeros(size(x)); % filter the signal
for i = D + 1 : 1 : xlen;
y(i) = x(i) + a*x(i-D);
end;
sound(y, fs); %play the echo signal
plot(y) % add labels on plot…use xlabel and ylabel
f=fft(y) % get the fast fourier transform of sound file
whos % checks the variables used and the size check out f
plot(abs(f)) %plot magnitude of the fft(frequency content of speech)
plot(abs(f(1:50000))) % plots a section of the fft
