The world is tend now a lot of development in communication field specially in internet , therefore it is very important to find security methods for files that is send from one place to another. One of these security approaches is steganography which have characteristic of transfer massages within transmission media (files) without notice from any obtrusive. This paper provide anew suggested method for hiding text in audio file (wav file), first the text file will be read to extract the massage which is hidden, for more security this massage will be encrypted (or coded ) before hiding it inside sound media (in time domain) . This algorithm was applied on more than one example and good results were obtained without missing the text massage or notice any noise in the cover file.
