Appendix a: Configuring CoreAudio (Mac OS X Only) 23
Configuring a Pro Tools|HD
Audio Interface for Third-Party
Applications
When using a Pro Tools|HD Native with an ap-
plication other than Pro Tools (such as Apple
GarageBand), you can configure hardware set-
tings through the audio preference settings
available in that application.
To configure hardware settings through a client
application (such as Apple GarageBand):
1 Choose CoreAudio for Audio Output and Au-
dio Input.
2 Select a buffer size for your system by selecting
an Optimize For option (Maximum/Large buffer
size or Minimum/Small buffer size).
Refer to the documentation for your third-party
application to learn more about how these op-
tions affect that application.
Configuring the Apple Sound
Preferences or Apple Audio
MIDI Setup
(Required for Using Qualified Pro Tools System
Interface with Apple iTunes or QuickTime
Player)
To use your Pro Tools hardware with certain
CoreAudio-compatible playback applications
(such as Apple iTunes or QuickTime Player), you
will need to configure either Sound Preferences
or Audio MIDI Setup in addition to CoreAudio
Manager. However, for most CoreAudio-com-
patible client applications (such as BIAS Peak or
Ableton Live) this is unnecessary, because you
can configure the CoreAudio Buffer Size setting
and input and output channels from within the
client application.
Apple Sound Preferences
To configure the Apple Sound Preferences:
1 Launch System Preferences (Apple menu > Sys-
tem Preferences).
2 Click Sound.
3 Click Output and select Pro Tools HD Native as
the device for sound output.
4 Click Input and select Pro Tools HD Native as the
device for sound input.
5 Quit System Preferences.
