Steganography, the idea of hiding messages and data within other pieces of data, can be useful in many real world applications alongside encryption and other code-writing methods. Data hiding methods are a new kind of technology in secret communication. Multimedia objects like audio are the most used in today’s information hiding systems. Audio file due to its high degree of redundancy and high data transmission rate can create a good hiding medium. Several formats such as MP3 have been used in audio data steganography. Varieties of methods have been established for embedding data in digital audio. In this article, in addition to more emphasis on MPEG-1 layer III (MP3) steganography methods with thorough information about weaknesses and strengths of these techniques, we present a complete study of audio file steganography approaches.
