Burn Options
Logic can directly burn Red Book audio to blank CDs.
Should the selected sample rate be higher than 44.1 kHz, a copy of the bounced PCM
file is created—with an automatic sample rate conversion to 44.1 kHz before encoding.
This conversion takes place because the CD Audio format (Red Book) does not support
sampling rates higher than 48 kHz.
Note: Should your system contain multiple CD burners, the first one detected is used.
Important: Some of the options listed below will only become active when blank CD
media is physically placed in the CD recording mechanism.
Simulate write only
The Simulate write only option requires that a blank CD be inserted into the SuperDrive
or ComboDrive. As the name suggests, this will simulate a CD burn, but will write no
data to the blank media. This can be used either alone, or in conjunction with, the Write
as multi session option.
Write as multi session
The Write as multi session option allows you to add a data session to the same CD at a
later date—to add the Project folder, for example.
Speed
The first time you use the Speed pull-down menu, a request is made to the CD burning
mechanism, which may take a while. Once the scan is complete, you may freely select
from the available speeds.
Dithering
Use of the Dithering parameter is recommended when bouncing 24 bit recordings into
16 bit files.
Burn
Clicking the Burn button initiates the Bounce and burns the audio to CD.
Note: Following confirmation of the file location(s), you may encounter further dialogs
that will ask if you want to overwrite existing files. Use these as required.
