Steganography is the art or science that is used in secret communication.It means that there is a secret message that is hidden within another cover media.The cover media may be image, video or audio and the secret message may be any type of digital message.The hidden message doesn't have any relationship with the cover media where the cover media is just to protect the secret message from hacking by unauthorized receiver.The audio cover is used in this paper because of the higher sensitivity of the human auditory system (HAS) than the human visual system (HVS).In this paper, we proposed a hybrid technique to audio steganography.This technique is based on a hybrid between two techniques of audio steganography.These techniques are Least Significant Bit (LSB) technique and modification of phase coding.The hybrid between them is for improving the performance of the phase coding where the performance of it is very low.Audio steganography performance is measured by several factors, the most important one of them is Signal to noise ratio (SNR) which is used to compare the performance of our technique with some known techniques.
