Configuring the Apple Sound
Preferences or Apple Audio
MIDI Setup
(Required for Using Avid Audio Interfaces with
Apple iTunes or QuickTime Player)
To use your Avid audio interface with certain
Core Audio–compatible playback applications
(such as Apple iTunes or QuickTime Player),
you will need to configure either Sound Prefer-
ences or Audio MIDI Setup in addition to Avid
Core Audio Manager. However, for most Core
Audio–compatible client applications (such as
BIAS Peak or Ableton Live) this is unnecessary
since you can configure the Core Audio Buffer
Size setting and audio input and output chan-
nels from within the client application.
