Chapter 11: Sessions 165
Using the Save Copy In command is the only way
to change the sample rate of a session. The sam-
ple rate of each of the session’s copied audio files
is converted to the selected sample rate. When
saving a session copy to a different sample rate,
Pro Tools uses the selected Sample Rate Conver-
sion Quality option in the Import section of the
Processing Preferences page (Setup > Prefer-
ences).
When you save a copy of the session to a lower
bit depth, Dither (and Noise Shaping) are ap-
plied. See the following table:
The dither setting used for any conversion is the
Dither plug-in with Noise Shaping enabled.
Save Copy In Options
When saving a copy of a session, the Save Copy

When saving sessions to versions lower
than Pro Tools 5.1, multichannel tracks
(including stereo) and multi-mono plug-ins
are lost. In this case, separate the tracks and
plug-ins to individual mono tracks before
saving as a Pro Tools 5.0 session or lower.
