Modern state-of-the art watermarking systems use precise algorithms for ensure perceptual transparency of the additional signal in the host signal presence. Various Human Auditory System (HAS) models are implemented but only few of them are computationally effective giving reliable acoustic masking effect. This paper presents efficient algorithm and its implementation for Just Noticeable Difference level estimation using HAS for data hiding application. Implementation is based on effective Johnston [1] HAS model and real-time processing using TMS 320C6713 DSK board. The results of implementation as well as subjective fidelity test using standard ITU-R BS 1116.1 are described and illustrated. Numerical results of DSP real-time implementation are compared with the Matlab off-line HAS computational model.
