| Abstract: | In this paper a novel method for digital audio steganography is presented where encrypted covert data is embedded into the
coefficients of the host audio (cover signal) in the integer wavelet domain. The hearing threshold is calculated in the integer
domain and this threshold is employed as the embedding threshold. The inverse integer wavelet transform is applied to the
modified coefficients to form a new audio sequence (stego signal). The characteristics of this method are large payload, high
audio quality and full recovery.
