Apollo Software Manual Chapter 9: Working With Apollo 160
Using Apollo as an Audio Interface
Apollo functions like other (non-DSP) audio interfaces when it is used without the Con-
sole application, the Console Recall plug-in, or UAD plug-ins. Apollo’s Core Audio drivers
enable it to be used for computer audio I/O routing with any Core Audio-compliant audio
software, including DAWs, music players (e.g., iTunes), system software alert sounds,
and similar applications.
Accessing Apollo I/O via Core Audio
Audio is routed to and from Apollo via its Core Audio device drivers. The audio software
accesses Core Audio interfaces directly via the audio settings/preference panel in the
audio software, or it uses the audio device set as the preference in the operating system.
Apollo I/O Driver Names
Each Apollo input and output has a channel number and name provided by the Apollo
drivers to Core Audio. If an audio software application can access Core Audio devices
directly, it may be possible to designate specific inputs and/or outputs within the appli-
cation.
All Apollo Driver I/O numbers and names are listed in “Driver I/O Tables” on page 185.
These values can be used to reference specific Apollo inputs or outputs by number or
name if allowed by the application.
Setting the I/O in the audio software application
To access Apollo’s I/O in an audio software application that can select Core Audio devices
directly, look for a setting in the audio software application’s preferences called “audio
setup” or “output device” or similar. Each application is different; consult the software
application documentation for specifics.
