山东大学本科毕业论文 影视后期制作音效制作技术研究与实现 摘 要 随着影视技术的发展和时代进步，人们对影视作品在视觉上的要求不断提升。然而在追求画质与剧情的不断提升之外，时常忽略了声音在画面背后的意义。从一开始人们试着在无声电影中加入现场的乐器演奏，到影视后期音效制作技术的出现，这期间已经产生了许多进步。然而，这项技术的完成却受到了许多约束。为了达到准确的描述，就必须对一部影视作品其视觉图像的运动和变化进行准确的剖析并在有限的时间中尽可能丰富地表现出来。 本文结合国内外几部电影对影视后期音效制作技术进行了分类和效果分析，然后结合影片的情节发展和人物心理走向，完成相应的音效处理与后期制作。其中，通过研究人物的性格特点和心理转变，对人物声音进行调整使其符合人物形象；通过影片剧情的发展和场景变换，对背景音效进行处理从而让观众感觉身临其境；通过对背景音乐环绕声的处理，增强影片的视听冲击。 通过对此项目课题的研究，进一步体现了音效制作对影视后期的重要性。一部好的影视作品，只有做到声音与画面有效的配合统一，才能进一步深化影片的艺术效果和主题风格。 关键字： 音效处理；后期制作；视听冲击 ABSTRACT With the development of film and TV technology and progress of the era, people have great expectation for the vision of film and television works. However, in the pursuit of quality and the improving of the plot, they often ignore the sound effect behind the scenes. At the beginning, people tried to put the sound of instruments in silent films, then the digital audio technology emerged, a lot of progress had made during this period. However, the completion of the technology has received many constraints. In order to achieve accurate description, the visual image of the movement and change in a movie has to be analyzed accurately and showed as rich as possible in the limited time. Following the films plot development and the character psychology, this paper does the research and deals with audio processing and production. By adjusting the sound of characters to comply with the characters personality and psychological change; by dealing with the background sound effect to let the audience overwhelmed through the development of the plot and change of the scenes; by dealing with the background surround music to enhance the films audio and visual impact. Through the study of this project, this paper shows the importance of sound production in the production of film and television technology. Only do sound effects and images cooperate unity effectively, can a good film and television works further deepen the art effect and the theme style. Keyword: Audio Processing; Post-prod
