Digital Audio In The Research On The Application Of Multimedia Teaching

Sound is teaching information carrier. Digital audio as multimedia material of multimedia teaching, is one of the important research content. Along with the information technology and the rapid development of computer technology, digital audio and related technology is mature, and various media information fusion of digital media and the development trend of the teaching media, digital audio applications to teaching is unstoppable, but also education technology research topic today. The multimedia teaching has wide application and promote teaching media, the optimized combination, improve the learners' interest in learning, but also improve the teaching efficiency and teaching quality. As one of the elements in the multimedia teaching in the teaching of the proper application of not only affect the mood and interest, learners and influence of knowledge of learners' acceptance. Although it has been generally realize the importance of the teaching resources on the audio, but carefully study will find, due to the audio resource file itself, but no larger volume of digital audio suitable for designers, resource database retrieval of audio resources of design and technology applied on the lack of adequate knowledge, people often only know its importance in practical application, shall not use, is the lack of design. Some teachers in multimedia teaching courseware on select material, or improper use, or in the technical requirement, real sets artistic quality and technology advanced educational, in a few good works. Therefore, the comprehensive use of audio system of theoretical research and technology for expansion, learning resources, improving teaching quality has important significance. This paper studies the digital audio LiTi in application of the multimedia teaching, for future study and design of audio resources to provide assistance.Currently, the study of the information resources of digital audio, mostly studied the technical aspects of the audio, but will be applied to the teaching of digital audio metagame study, based on this, the author in teaching theory and application of digital audio, a comprehensive analysis. This paper through the literature, journals and books through many experts, multimedia courseware, and related information, summarize and take example, contrast analysis method, through analysis of the characteristics of digital audio teaching and the design of digital audio frequency analysis, the application of digital audio in teaching research and systematic guidance and strong practicability.This was the first chapter of multimedia digital audio and the related concept, digital audio formats and characteristics, digital audio in multimedia teaching, and points out that the role of digital audio in multimedia teaching application problems, Chapter 2 introduces digital audio in detail the application of multimedia teaching theory, including the pedagogy theory, theory of education, psychology and aesthetic theory and the theory of communication education aesthetics, The third chapter of digital audio use cases were analyzed, and the excellent characteristics of digital audio use case, and puts forward the digital audio in multimedia teaching design principles of use. The fourth chapter through theoretical guidance for the design of digital audio using works, and summarizes the application of digital audio technology. The final paper summarized in this study.
