The course content includes an introduction to Chongqing cuisine, such as hotpot and noodles, and their uniqueness in audio representation. We will demonstrate through video to understand the generation of sound and the use of sound wave diagrams. The course focuses on the role of sound rhythm in attracting audience attention, creating atmosphere, guiding viewing rhythm, and enhancing memory points. We also systematically analyzed the sound types in food videos, including dialogue, ambient sound effects, sound effects, and music, and their roles in conveying information, enhancing realism, and setting emotional tones. Through this course, students will learn how to use audio elements to enhance the overall effect of food videos, providing viewers with an excellent visual and auditory experience.
