摘要：A Steganographic method for embedding textual information in WAV audio is discussed here. In the proposed method each audio sample is converted into bits and then the textual information is embedded in it. In embedding process, first the message character is converted into its equivalent binary. The last 4 bits of this binary is taken into consideration and applying redundancy of the binary code the prefix either 0 or 1 is used. To identify the uppercase, lower case, space,and number the control symbols in the form of binary is used. By using proposed LSB based algorithm, the capacity of stego system to hide the text increases. The performance evaluation is done on the basis of MOS by taking 20 samples and comparison of SNR values with some known and proposed algorithm
