Steganography is an art and branch of science of hiding data secretly. Steganography can be applied to various digital mediums such as image, text, audio, video, protocols, radio waves, floppy disk, hard drive, network packet etc. Audio steganography uses audio file as the cover medium. It is more difficult to implement than image steganography as Human Visual System (HVS) is less sensitive then Human audio system. ZDT enables to achieve this task and ensures no distortion in the cover audio file. Along with steganography this approach uses cryptography for security concern. Indexed Based Chaotic Sequence is used as an encryption technique. This technique is applied on several audio files and the obtained results shows efficiency, robustness, better complexity (time and space) in terms of performance analysis matrix.
