bility
to create session and audio files that can be

How the Save Copy In Command
Works
Unlike the Save As command, Save Copy In does
not close the original session, so subsequent edits
are made to the original session. Session copies
can be used to archive important sessions, for ver-
sioning, or as a means to prepare sessions for trans-
fer to another Pro Tools system.
Save Copy In can save only the audio being used in
the session. Any audio that was recorded or im-
ported and then later removed from the session, but
not deleted from disk, is not included in the new
session or project copy.
Using the
Save Copy In command is the only way
to change the sample rate of a session or project.
The sample rate of each of the session or project
copied audio files is converted to the selected sam-
ple rate. When saving a session copy to a different
sample rate, Pro Tools uses the selected
Sample
Rate Conversion Quality
option in the Import sec-
tion of the Processing Preferences page (
Setup >
Preferences
).
When you save a copy of the session or project to
a lower bit depth, Dither (and Noise Shaping) are
applied automatically.
See the following table:
The dither setting used for any conversion is the
Dither plug-in with
Noise Shaping enabled.
To include all audio being used in the session,
select the All Audio Files option.
To include all audio being used in the session
or project, select the All Audio Files option.
