Write CRC Checksums This option adds error-
detection data to the MP3 file. This data is not
necessary for most computer and Internet appli-
cations, and also takes away from the space
available for audio data. Select this option only
if you are sure your delivery mode requires error
correction.
Copyrighted This option sets a bit in the MP3
data stream to indicate that the audio is copy-
righted. Not all MP3 players use this informa-
tion. Selecting this option does not guarantee
that the audio file will not be copied.
Original This option sets a bit in the MP3 data
stream to indicate that the audio is the original
media for the track, rather than a copy. This set-
ting is not widely used.
Private This option sets a bit in the MP3 data
stream that is interpreted differently by various
applications. It is not normally used.
Mac File Settings
Mac File Type and Creator If you expect your file
to be used on a Macintosh, you can enter the
Macintosh file type and creator. This will allow
users to double-click the file to open their MP3
player.

Format
This is the format for the bounced result.
Choices are Mono (summed), Multiple mono,
and Interleaved.
To set the bounce file format:
■ Select a file format from the Format Selector.
Mono (Summed) Creates a single disk file that is
a summed mono mix of the current sources be-
ing monitored.
When bouncing to mono (summed) files, the
output may clip. Avoid clipping by monitoring
the meters of your bounce source Auxiliary In-
put or Master Fader. When bouncing stereo
tracks to mono (summed) files, clipping occurs
if left and right signals exceed –3 dB below max-
imum, or full code (0 dBFS).
Multiple Mono Creates multiple mono files with
the same number of channels as the source
path.
•If the source output or bus path is stereo, two
mono files will be created, and appended with
“.L” and “.R” suffixes on bounce.
• If a multichannel format is used (for example,
six-channel, 5.1), individual mono files will
be created for each member of the path. Files
will be appended with path suffixes according
to the path definition in the I/O Setup dialog.
• If the source output or bus path is mono, the
pop-up menu will switch from multiple mono
to mono, and will create one mono file (no
summing of multiple sources).
Stereo Interleaved Creates a single, interleaved
file that contains all of the bounced streams
from the chosen output path. In an interleaved
stereo bounce, tracks assigned to odd-numbered
outputs are sent to the left channel, and tracks
assigned to even-numbered outputs are sent to
the right channel.
