Recently, security of audio data has pulled much attention as any other security systems. Security becomes obvious, especially when these audios are being sent through a communication network. An audio encryption technique transforms an audio to another audio, which is very difficult to interpret.In this issue, we are proposing an encryption system methodology for WAV audios, which is the most widely used audio format.This Algorithm is based on the characteristics of genetic algorithms.Also in this, we introduce an ambiguity factor to our audio encryption system where we can send or store our audio in form of an image or embedded in another image by steganography, which makes it very hard to guess about the kind and nature of data stored in the file.Performance analysis of proposed algorithm confirms that it has good key sensitivity, statistical character and can also is resistant to brute-force attacks, differential attacks, plaintext attacks and entropy attacks quite efficiently.
