The course of digital audio production in the modern college curriculum teaching system is mainly oriented at students majoring in digital media and animation. However, the existing teaching pattern dominated by movie and TV appreciation is already out-of-date and does not suit the full-media teaching development in the new era. In this study about auditory language analysis of movies, we probed into the expressing ways and patterns of auditory language under the modern production techniques and conditions, discussed the important effects of auditory language on the overall effects of movies, and explored the new teaching patterns of digital audio production. Appreciation from aspects of human voice, audio and music was taught with relevant cases of teaching as example. The advancements of modern production technology brought new techniques, methods and patterns for the production and innovation of auditory language. Then a novel teaching pattern of “movie and TV teaching, case production” and starting from rationale understanding to practical application was established and used to uncover the bonding relationships among production techniques, methods and effects of auditory language that were needed by any successful movie. This new teaching pattern will offer some theoretical guidance for the teaching practice of digital autio production.

At present, capacity is the prevailing paradigm for covert channels and most of current researches are based on Shannon’s channel theory. With respect to steganography, however, capacity is insufficient. Ira S. Moskowitz et al propose “capability” paradigm in [1], but they had not given a feasible algorithm for “capability” description. In this paper, a new capability description for audio information hiding is proposed and a feasible mathematic method is given to determine how much information can be hiding. The proposed capability description can be used to give a prediction framework of steganographic communication in our speech steganography system.
