Sync Sound

Sync Sound or Double-System sound is the method of recording audio on two separate systems while keeping audio and picture in sync for situations when solid audio capture is most critical. The primary or master recorder is usually a disk based digital audio recorder, like the Zaxcom Nomad, and offers more tracks and a higher quality recording. The secondary or slave recorder is usually the camera being used or a record deck. The method to sync sound to picture uses something called LTC, or timecode. Timecode is the reference that allows picture and sound to reconnect in post production with very precise accuracy. Optimum Dynamics uses sync tools by Denecke, such as a smartslate and lockit boxes.
