sir @Walter Roberson, i have infants cry signals of short duration as my samples. normal baby,jaundice and Apnea disease baby. now want to classify them. For using ANN, we need inputs in binary form.0's and 1's. my samples are stored in .wav format. how to go ahead?

You have digital computer files that represent sounds. Why are these .wav files already not in binary form? Did you use wavread() to read them in? Now you have numbers that represent the strength of the signal at each time point. A number is binary, like 9 is 1001 when you look at the low level computer storage of it. So, what do you mean?
