Pro Tools Reference Guide 354
Normal (Nondestructive) Record Mode
In Normal, Nondestructive Record mode,
Pro Tools records audio nondestructively, which
means that if you record over a track’s existing
regions, the audio is not erased from your hard
drive. Both the new and old audio files remain
on your hard drive, available as regions from the
Region List.
In Normal Record mode, the record range can be
defined by selecting a range in a ruler or in a
track’s playlist, or by specifying start and end
points in the Transport window. If there is no
selection, recording begins from the current
Cursor location and continues until the Trans-
port’s Stop button is clicked.
The pre- and post-roll settings allow material to
be heard up to and after the start and end
points, which is useful when punch recording
(see “Audio Punch Recording Over a Specified
Range” on page 377).
Destructive Record Mode
In Destructive Record mode, recording over ex-
isting regions replaces the original audio perma-
nently, which allows you to keep disk use to a
minimum. However, if you have sufficient drive
space, it is usually best to use Pro Tools in Non-
destructive Record mode, to avoid losing any
previously recorded material.
When defining the record range and setting pre-
and post-roll, Destructive Record mode works
the same as Normal (Nondestructive) mode.
Unlike the other record modes, it is not possible
to cancel or undo record takes when using De-
structive Record mode (see “Canceling a Record
Take” on page 371).
Loop Record Mode
Loop Record mode lets you record take after take
(nondestructively) while the same section of au-
dio repeats. This is a convenient technique for
quickly recording multiple takes of a part with-
out losing spontaneity.
The time range that is looped and recorded—
which must be at least one second in length—is
defined by selecting a range in a ruler or in a
track’s playlist, or by specifying start and end
points in the Transport window. The pre-roll
setting, if enabled, is used during the first record
pass, but on each successive loop the pre- and
post-roll times are ignored.
When using Loop Record mode, each successive
take appears as a region in the Region List and
each is numbered sequentially. The various
takes, which are identical in length and start
time, are easily auditioned and placed in the
track at the correct location with the Matches
pop-up menu (see “Selecting Alternate Takes”
on page 383).
To set a record range by selecting within a
track’s playlist, the Timeline and Edit selec-
tions must be linked. See “Linking or Un-
linking Timeline and Edit Selections” on
page 473.
In Destructive Record mode, the waveform
overview is not redrawn until you stop
recording.
To set a record range by selecting within a
track’s playlist, enable the Link Timeline
and Edit Selection option. See “Linking or
Unlinking Timeline and Edit Selections” on
page 473.
In Loop Record mode, the waveform over-
view is not redrawn until you stop
recording.
