Steganography is an information hiding technique where secret message is embedded into unsuspicious cover signal. Measurement of good steganography algorithm includes security, capacity, robustness and imperceptibility. These measures are contradicted, therefore improving one, affects the others. In this paper, we propose a new high capacity audio steganography algorithm based on the wavelet packet transform with adaptive hiding in least significant bits. The adaptive hiding is determined depend on the cover samples strength and bits block matching between message and cover signals. The results show that message can be embedded up to 42 % of the total size of the cover audio signal with at least of 50 dB signal to noise ratio. � 2011 IEEE.
