声频技术从1877年美国爱迪生(Edison)发明圆筒留声机算起,已经经历了一百多年。在前一百年期间一直是以模拟声频技术(Analogue Audio Technique)为主的。随着广播技术的飞速发展,我们已经迎来了广播数字化时代。这就需要我们从业者尽快地掌握计算机技术、网络技术,了解广播电视的声频的处理、变换、传输和再现的全过程,掌握数字广播设备的工作原理和技术特点,并利用现代先进的教育教学技术和手段教授给学生。
Audio technology has been around for over a hundred years since Edison invented the cylinder phonograph in 1877. Analogue Audio Technique dominated the first hundred years. With the rapid development of broadcasting technology, we have ushered in the digital broadcasting era. This requires our practitioners to grasp the computer technology and network technology as soon as possible to understand the whole process of audio and video processing, transformation, transmission and reproduction of broadcasting and television, master the working principle and technical characteristics of digital broadcasting equipment, and make use of modern advanced education and teaching Professor of technology and tools to students.
