Linear timecode

Longitudinal ( or linear ) Timecode ( LTC), pronounced " lit -si " is a timecode type that is on certain magnetic tapes recorded along (eg SVHS ) of the band. Mostly for an audio track is sacrificed.

The advantages of LTC are that it can be read in contrast to Vertical Interval Time Code ( VITC), even during a rapid preroll and can also be subsequently recorded.

The downside of LTC is that it can not be read from stills or during the slow preroll, which is possible with VITC.

In audio engineering LTC plays a key role in the synchronization between multiple analog tape or a tape recorder and a digital audio workstation (DAW ). One or more devices are called " Slave" a "master " subordinate. You go on the timeline as soon as possible after the movements and actions of the master. Following the same principle, the procedure also when synchronizing tape machines, sequencers, DAWs and film projectors.
