![]() OBS is great broadcasting software and handles many sophisticated internal features. When a chunk of audio data gets combined with a chunk of video data that represents two different points in time, the broadcast will be out of sync. The audio is often ready to stream slightly ahead of the video. It takes more cycles, or computing power, to process video than it takes to process audio. There can be a number of contributing factors why this occurs, but the chief reason is a slow computer / CPU. It is like watching a badly dubbed foreign movie. When the audio and video get “out of sync,” you witness the phenomenon where you see the lips move but hear the voice slightly later, or vice versa. It is the synchronization of the audio with the video. We’ll go into more detail about improving latency in another blog.Īudio Sync Audio Sync is today’s topic. ![]() Improving latency is a factor of improving your internet connection (upgrading to a better ISP or broadband connection) and reducing the amount of data your stream (turn down your broadcast quality). As a broadcaster, you all have experienced this when you ask your audience a question and have to wait until they respond. Different viewers will experience the live broadcast at different times than other viewers. This time is based on the internet speed of the broadcaster AND the viewer. Many factors determine how long this can take, anywhere from a few seconds to 20 or more seconds. Latency Latency is the term we use to describe the time it takes from the broadcaster to send his or her stream up to the internet, travel across the planet, and get pulled down to the viewer’s computer. Let’s define when people say lag, but really mean… You often hear audio issues called “lag.” However, that term gets confusing since many people use it as a catch-all phrase. Ever notice a live stream that has audio a little off from the video? We’ll help you fix that when broadcasting with OBS Studio.
