Ring Buffer
• AKA:
•
Short definition:
In the Session recording context, the “Ring Buffer” is a cyclic FIFO memory buffer
which continually preloads 60 seconds of audio from all record-enabled inputs.
•
Details:
Audio stored in the ring buffer is used for data integrity insurance and for insertion as preroll
audio before the beginning of a Take.
Postroll
• AKA:
•
Short definition:
A timer that delays disengaging record mode for a set time after the transport re-
ceives an automated “End Take” command
•
Details:
“Postroll” is most often used to capture long ringouts which might otherwise fall below Level
De-trigger settings, and/or to act as a pseudo-freewheel over broken or unstable timecode when
in Timecode trigger record mode
Record Trigger mode
• AKA:
•
Short definition:
The four methods in Session which can engage Record Mode, specifically, “Manual“,
“Level“, “Timecode“ and “Autopunch“
•
Details:
follow below
Manual (Record Trigger mode)
• AKA:
•
Short definition:
Record Mode can only be engaged by a manual command, i.e., a button click, key
command or control surface command
•
Details:
Level Trigger
• AKA:
•
Short definition:
In Level Trigger mode, the amplitude setting (in dBFS) at which Record Mode will
be engaged.
•
Details:
When the input level at at Record Enabled Input reaches the Level Trigger setting, the
recordhead starts moving and a new Take is recorded.
Level De-trigger
• AKA:
•
Short definition:
In Level Trigger mode, the amplitude setting (in dBFS) at which Record Mode will
be disengaged.
•
Details:
when the input level at at Record Enabled Input falls below the Level De-trigger setting,
the Postroll timer is engaged. If the input level reaches the Level Trigger setting before the Postroll
times out, the Postroll timer is reset and the Take continues uninterrupted. Otherwise when Postroll
times out, Session enters “Record Standby“ mode, awaiting a new Level Trigger.
Timecode Trigger
• AKA:
•
Short definition:
In Timecode Trigger Mode, the presence of stable SMPTE at the selected SMPTE
input port triggers Record Start (starting a new Take).
•
Details:
Note: Session Transport does not lock to SMPTE timestamp.
