APIC is a cloud-sourcing platform to understand the human perception of digital multimedia. Due to the network steam transmission fluctuation and hardware communication asynchrony, the visual image and audio sound may happen with mistiming. However, human perception is with the ability to infer the content source of the clips. Hence, extreme tiny mistiming can be corrected by perception unconscious. We want to further understand the role of perception in the audiovisual asynchrony. The platform provides asynchrony clips with kinds of contents and mistiming. Participants should adjust soundtracks until they feel the video is synchronized. We analyze the operation during adjusting and final synchronous point. A questionnaire is offered after experiment. We will also search the potential linkage between human culture background and the ability of audiovisual integration.
