Session Parameters
Audio File Type
You can save the session to reference BWF
(.WAV) or AIFF audio files. On the Macintosh,
you can also save the session to reference SD II
audio files (at sample rates up to 48 kHz).
Using Mixed File Types
A session can use mixed audio file types. If your
original session has mixed file types, they are
not converted to a different file type unless you
specify that they be converted. However, when
using mixed file types, audio performance will
be reduced (due to additional file handling re-
quired for some file formats).
Bit Depth
You can save the new session at 16-bit or 24-bit
depth. If your session is in a different bit depth,
audio files are converted to the new session bit
depth, and copied to the location you specify.
Sample Rate
You can save the new session at sample rates of
44.1 kHz or 48 kHz (on Mbox, Digi 001 and
MIX-series systems) and at sample rates up to
96 kHz (on Digi 002, Digi 002 Rack and HD-se-
ries systems with a 96 I/O or 96i I/O) or up to
192 kHz (on HD-series systems with a 192 I/O or
192 Digital I/O). If your session is at a different
sample rate, audio files are converted to the new
session sample rate, and copied to the location
you specify.
The higher the quality of sample rate conver-
sion you choose, the longer Pro Tools will take
to process the audio file.
Fader Gain
You can save the new session with a +6 dB or a
+12 dB maximum fader gain. When saving a
+12 dB session as a +6 dB session, Pro Tools
alerts you that any automation breakpoints over
+6 dB will be lowered to +6 dB.
Enforce Mac/PC Compatibility
This setting forces Windows or Macintosh ver-
sions of Pro Tools to create sessions and audio
files that are usable on both platforms. For more
information, see “Creating Macintosh and PC
Compatible Sessions” on page 131.
Items to Copy
All Audio Files
When this option is selected, all audio files are
copied to the new location.
This setting is automatically selected if you are
changing the bit depth or sample rate of the ses-
sion.
All (Non-Native) Audio Files
The name of this option varies depending on
the audio file type you select. If you are chang-
ing the audio file type of the session, this option
ensures that all files in the copied session are
converted to the selected file type. Use this op-
tion to avoid the reduced performance of a ses-
sion with mixed file types.
This option is automatically selected if you are
changing bit depth or sample rate, or copying a
session on the Macintosh from SD II format to
AIFF or BWF (.WAV) format with Enforce
Mac/PC Compatibility selected.
SD II sessions are not supported with
Pro Tools for Windows, or with sample
rates higher than 48 kHz. You cannot set
the session audio file type to SD II on the
Macintosh if Enforce Mac/PC Compatibil-
ity is selected, or if the sample rate of the
destination session is greater than 48 kHz.
