"The clapboard, developed in the 1920s, still serves as the best way to sync audio and video"
The Audio Engineering Society held its annual convention in New York this past weekend, and
HD audio and the multitude of challenges involved in delivering a quality experience were at
the center of broadcast-audio discussions.
Problems with maintaining proper lip sync, for example, can quickly lead to issues that bother
more than just engineering types. A recent study conducted by Stanford University found that
when audio precedes video by five video fields, consumers respond viscerally and will view
the person speaking more negatively, perceiving them to be agitated and less successful
than people speaking in proper sync.
Adding to the complexity, the sharper images of HD mean that it is possible that it will be
