Synchronizing
the
audio
portions
of
a
film
is
done
by
transferring
the
DAT
cassette
or
Nagra
reel
to
reel
audio
tapes
to
a
magnetically
coated
roll
of
film
know
as
"mag-track"
complete
with
perfs.
The
device
doing
the
tape
to
mag-track
transfer
ensures
that
the
speed
of
the
audio
on
the
mag-track
matches
the
speed
of
the
film
frame
by
frame.
Traditionally,
once
the
audio
has
all
been
transferred
to
mag-track,
it
can
be
synchronized
and
edited
to
exactly
match
the
picture
by
using
rewinds
or
a
Moviola.
Now
however,
most
audio
editors
work
digitally
for
both
film
and
video
using
Adobe
Premiere
(on
the
low
end)
in
conjunction
with
Sound
Forge
that
get
pretty
close
results
to
the
high
end
Avid
system
and
Pro
Tools
software.
