Sync Track
A sync track carries a synchronization signal alongside open-reel audio to coordinate recording with film, video or another machine.
The signal may be a pilot tone or timecode on a dedicated track. Its purpose is to maintain a timing relationship with other equipment. This differs from monitoring an existing audio track through the record head during overdubbing.
Sync Track — Reel-to-Reel
A sync-equipped recorder can record or read timing information for a coordinated production system. Pilot-tone arrangements provide a timing reference, while timecode identifies positions using a code format. The supported system determines what synchronizing equipment and track arrangement are needed.
Compare the named sync system and whether the machine records, reads or supports both functions. Timecode format and dedicated-track compatibility matter beyond the presence of a connector. Sel-sync is record-head playback for aligned overdubbing, not a separate synchronization track. An ordinary tape counter or programme cue does not establish compatibility with film or video timing.
