2:1 Compressed is a
format which does some squeezing
to
save the
same
amount
of
information in half the
space,

same
as
above hut compacting even
more. The difference bern'een 2:1

The
greatest
difference
between a
compressed files and a non-compressed file
is
the
amount of space
it takes to store the file
.
Another
difference is that the fidelity may be decreased by
the
compression. The quality
loss is
very slight,
especially
in the
case of voice recordings,
Try
saving
a file in both the
compressed
formats
and compare
disk
space and
quality
with
the
original.
Raw Data is a mono fil
e
saved in straight
binary format.
This
means that
information,
such
as
the
speed at which
the file
was
recorded,
is not saved in
this
format. If you're
saving
a
file recorded in
stereo as
raw data, the two
channels
will
be
combined into
one
channel
and
saved as a mono file
.
When
raw data files are loaded, the playback rate is set to the
default
setting of 22,200 Hz .

Note:
If you plan to use
a
program or desk
accessory
that plays back
sound
files,
other
than th
e
ones
provided
with the
Audio
Animator, you'll need
to find out the program's or desk accessory's default
playback
rate (if it does not let
you
set the
playback
rate)
and
record your sound files at that speed
before saving
as Raw
Data.
Try
saving
the same file in the different formats and then play
them back
and check
the amount
of
memory used to
determine if you
can
tell a difference.
Delete ...
Delete is
extremely
useful for
getting
rid of files you no longer
want in order to make room for new files. When you
choose
Delete, you'll be
presented
with the Open
dialog.
However,
the Open button is now the Delete
button.
Choose the
disk
that contains the file you want to delete. If the file is in
a
folder, double-click on the folder to open it. Click on the file
you want to delete and then click Delete. You'll be asked if
you want to delete the file you've selected
(a
safety
precaution). Click Yes to delete or
No
to
return to
the
main
screen without deleting the
file.
