Measuring Lip Sync Error Using the Harkwood Sync-One2

The Harkwood Sync-One2 is a tool designed to measure the lip sync error of a full AV setup involving a source device, transport interface, and sink device, such as a cinema, a video production workstation, a specific Blu-Ray player paired with a TV and sound system, etc. It can be used to calibrate a setup based on the time it takes for sound to travel from the speakers to the listening position.

⚠️ Important notes regarding sink device(s):

It is not easy to accurately measure the lip sync error of only your sink device with this tool because you are just as likely to be measuring the lip sync error of your source as you are to be measuring the lip sync error of your sink device.

To measure the lip sync error that is specific to your sink devices, you can use these other methods.
