this paper presents a new audio encryption algorithm based on permutation and residue number system. in the current approach, signal samples are combined with residue number system through permutation; therefore, a specific noise is generated. then, the audio signal is combined with the noise, generated by the algorithm, to produce a silence signal. for this purpose, the algorithm uses a predef...

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...

This work reviews the human auditory system, elucidating some of specialized mechanisms and non-linear pathways along chain events between physical sound its perception. Customary relationships frequency, time, phase--such as uncertainty principle--that hold for linear systems, do not apply straightforwardly to hearing process. Auditory temporal resolution certain processes can be a hundredth p...
