The art of information hiding has done much progress in the recent years as security of information has become a big issue in this online communication era. The demand of security and privacy is increasing for confidential matter day by day, necessity of covering valuable and secret information have much importance during online communication. To fulfil this necessity, Steganography technique is very much useful which embed information in a digital media in such transparent way so no one should able to understand it. Audio Steganography is one of the most prominent and recognized technique. As it is known, imperceptibility, robustness and payload or hiding capacity are pillars of the steganography. The previous LSB techniques when increases payload capacity would hamper robustness as well as imperceptibility of the cover media. As well as when it matters of robustness to maintain then hiding capacity gets limited. This paper includes study of some audio steganography techniques with their merits and demerits. This paper proposes an audio steganography technique to improve the performance. The proposed method will provide optimum increment in the payload capacity by dividing the bytes of cover media into ranges to hide the bits of secret message appropriately. Use of range to hide secret data will maintain the robustness of cover media along with preserving the imperceptibility.
