Instead of
wavwrite(x.(f{1}),8000,'foo.wav')
try
nBits = 16;
Y = x.(f{1});
Y = Y./max(abs(Y(:)))*(1-(2^-(nBits-1)));
wavwrite(Y,8000,nBits,'foo.wav')

The error means that at least for one sample either x<-1 or x>1.

Thank you equals a vote. I wasn't suggesting you ask in that thread, but rather, that the answer was in the thread.
