The OBS Audio and Video Sync Tool has been designed to answer the important question of how much audio delay an Open Broadcaster Software user should apply in their live streaming system. The tool is a video that combines a visual scale of time with a countdown timer looping in sync with audio blips every second. OBS users can capture a video and audio recording of this tool to accurately determine the amount of audio delay they should apply to their live streaming system to sync up their audio and video streams.
