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