In today's digital world one is concerned with the secrecy of data and focused on copyright-dependent individuals and organizations, specifically in the domain of the entertainment industry. The variations in the human voice lead to the difficulties to generate the watermark to the audio signals in order to preserve them from unauthenticated access. The major objective of the steganography process is to enhance the security of the transmitted data. The unauthorized user can not access or misuse the steganographic file. Audio steganography is also applicable to the non-technical fields in order to keep the privacy and security of the data. This paper presents a review of recent research on audio steganography. The major focus of the study is to address various types of audio steganographic techniques along with their pros and cons. There is a need to find technique so that the data hiding is done more securely and it is not possible for the third parties to detect the data in bits.
