SMPTE Tab
This is where you adjust Adobe Audition’s settings for working with time code.
The SMPTE tab of the Settings dialog
Lead Time This sets is the amount of time (measured in milliseconds) that Adobe Audition has to establish sync with the
incoming time code. Lower settings (200ms) will result in faster response (when pressing Play), but at the risk of true
sync not being established. 500ms to 1000ms should provide plenty of Lead Time to establish lock-up. The default value
is 200ms.
Stopping Time Stopping Time is the amount of time (measured in milliseconds) Adobe Audition will continue playing
if a dropout in the time code is encountered. The default value is 1000ms.
Lag Time This setting, measured in samples, fine tunes the relationship between time code coming in and audio data
coming out. It can be used to make up for any discrepancies introduced by your sound card buffers. The default value is
10 samples.
Slack This sets the number of frames CEP can periodically be “out of sync” with the time code before either reposi-
tioning the playback cursor to match the code, or perform a full re-sync. Generally a setting of about 2.5 frames will do,
as there are occasions when the time code frame location numbers may be incorrect, usually corrected on the next frame
sent. This will not cause a sync problem in the audio sense. The default value is 1 frame.
Clock Drift Correction Time This specifies how many samples to crossfade when making time corrections to audio played
back, so the playback chases the time code. The default value is 200 samples.
Reposition playback cursor when shuttling If selected, the playback position will readjust if the sync is off by the Slack
amount.
Full re-sync when shuttling If selected, a full re-sync will be performed if the sync is off by the Slack amount.
