Everyone has seen presenters tapping on their microphones saying “one, two…” and clapper boards, which were invented in the early days of motion pictures to synchronise vision and sound.
These methods rely on a human, subjective interpretation of whether a sound is in sync with the video. This is hard to rely on for accuracy, especially as distances between the subject and a master control room increase. And any misalignments are much more noticeable these days with audiences enjoying hyper-clear pictures and near cinema-quality audio in the home. Even the slightest mismatch of sound and video is noticeable and all too often can lead to viewers switching channels.
Hitomi takes guesswork out of the equation, replacing subjective estimates with highly accurate, mechanised test audio and video generators along with a state-of-the-art analyser.
