Double System Audio
- VPAudio that is recorded with a separate audio recorder apart from the camera. When shooting double system, the audio is synched up with the picture by using a clapper slate, so the sound of the clap can be aligned with physical clap seen on camera. It is also common when shooting video to record a "dirty" reference track with a camera mic to assist with synching.
