the transform domain. To be specific, wavelet domain is used here, to encode the data. A wavelet is a waveform of limited duration that has an average value of zero. E.g. Haar Wavelet as shown in the Figure 1. Figure 1- Haar Wavelet The Haar wavelet transform decomposes a discrete signal into two sub-signals of half its length.

of a signal simultaneously Wavelet transform is a useful tool as it provides a lot of application and compression is one of them. Wavelet transform is being used here because it provides various options for selecting the best wavelet for the compression. Wavelet transform includes the decomposition of a signal in approximation and detail parts. Approximation

digital audio streams and the size of the audio. An effective Discrete Wavelet Transform (DWT) is used at various scales for the decomposition of the original signal into wavelet coefficients. To secure the processed audio signal, Audio Steganography is used. Steganography is the art of secret hiding and its study. The origin

Audio steganography is defined as the Cover Audio + Secret data = Stego-audio signal [ 6, 7, 8 ]. The essential requirements for audio steganography are: (1) the secret data should not be perceptible to humans [ 6, 7 ]; (2) it should maximize the hiding capacity; and (3) preferably, the hidden data should be encrypted.
