This paper will provide two data hiding methods which will embed secret information in a digital audio media. One will embed data in a audio file expressed in the time domain, it provides high embedding capacity. The other in the frequency domain, it can resist audio compression under adding the error control code in the secret information. These two methods utilize some characteristics of sound, for example, loud sound can mask out quiet sound. Experimental results also show the effectiveness of these two methods.
