Audio Clock

Clock Device - Interpret external audio timecode

audio clock allows to interpret external audio timecode LTC of a configured Audio Input Device.
Go check the Clock Device In use to bind an animation to Time Code Read More topic to see how to bind a timeline to a clock
To set an Audio Clock, go inside EDITMenu for Copy/Paste and Undo/Redo operations > Preferences > Engine > Clock Inputs or press "F11". Add a device and the choose an Audio Clock:

Then go configure an Audio Device Use audio in Smode Read More to get an audio Input.
If you get seeking issues in your timeline, it probably is a buffer / signal issue. First check that you receive a clear signal (green arrow).
If the issue remain, edit your devices (1) and try to increase the sample rate and buffer size using the menu presets (2):

Not that you also have acces to a "manual override" inside the device panel, this will allow to pass this clock into a Manual Clock Set the time you want Read More which will override the audio signal.

Parameters common to all Stream Clocks

  • Transmission Delay (Floating point number) : Transmission delay to subtract from the playing audio clock time, before sending to linked cues transports
  • Global Offset (Floating point number) : Time offset added to audio clock time (whether playing or not), before sending to linked cues transports
  • No Signal Threshold (Positive floating point number) : No signal threshold of the audio clock is used to let the clock run in case of short disconnection, this avoid to be interpreted as clock pause
  • Resync Now (Trigger) : Trig to enforce re-sync of audio clock
  • Reception Warnings (Positive floating point number) : Number of warnings in the signal reception. (Read Only) Note that it is normal to have a few warnings when seeking with LTC/MTC. In case of many continuously increasing reception warnings with LTC, check your audio signal and try increasing the audio input device buffer size.
