Basically, a steganography indicates two of the principal requirements such the messages and the carrier file. Besides, it should have three aspects: capacity, imperceptibility, and robustness. This paper will show how to enhance the capacity of two types of carrier files for embedding message. By using least significant bit method and modifying the four last bits of carrier files, bitmap and wav files could show the increasing of message size to be inserted to the carrier than only modifying the last 1 bit of carrier files.
