Security in data communication is a very important concern today. It is used in almost every region like e-commerce, education, and industry and data warehouse. Steganography literally means secret writing. The technique has been used in various forms for 2500 years or long but in the last two decades Steganography has been introduced to digital media. The goal of steganography is to hide information by concealing it into some other medium like image, audio or video so that only sender and intended recipient knows existence of information in communication. So the main focus of this paper is to study and discuss the trends which are already been proposed in the direction of cryptography and steganography. The main focus of this paper is on emerging concepts and recent techniques like Parity Coding, Least Significant Bit Coding (LSB), Phase Coding, Echo Data Hiding, Spread Spectrum about audio steganography. The performance of recent audio steganography techniques on the basis of strengths, weaknesses and hiding rate is evaluated. Some advancement like Generic Algorithm based Audio Steganography and steganalysis concepts are also discussed.
