Audio-to-image wavelet transform based audio steganography
Resvicar Alwan Pratama Santosa, Paul G. Bao · 2005
In this paper, we propose an audio steganographic scheme based on wavelet audio-to-image transform. The scheme converts the audio steganographic issue into well-explored image steganographic one. In the scheme, the host audio signal is transformed into image, the covert data are embedded in the image by an image steganographic scheme and finally, the image is transformed back into audio signal. The performance of the proposed scheme under MP3 compression is shown in the experimental results
