Abstract:

After studying about human auditory system and narrowband communications system model, a narrowband audio hiding algorithm based on human auditory system was presented. A lot of experiments proved that the algorithm had strong robustness to prevent many attacks from such as D/A, A/D, channel noise and so on. In time domain, frequency domain, especially for hearing, it had high transparence. What’s more, the algorithm, whose hiding capacity reached up to 20 bit/s, had intelligent blind detection property and can be used in many domains.

Key words: human auditory system, narrowband communications, audio hiding, intelligence training
