PC And ASIO Drivers
There are a few extra ASIO related options available for PC users. These options are not relevant to
Mac users.
Use ASIO direct mode: This option may improve performance with some ASIO drivers. Typically it is
benign at worst, and many USB devices will benet from it, so it is probably worth leaving it enabled. If
you are having problems with sound in Tracktion, you should try toggling this setting though.
If ASIO Direct mode is turned off, then Tracktion will use a slower but safer method of working with
ASIO drivers.
Show ASIO control panel: This button displays the control panel for the currently selected ASIO
device. Please note, the screen you see here will be specic to your hardware, so refer to the docu-
mentation that came with your audio hardware for further information.
Use real-time priority mode: This option can help with compatibility for some ASIO sound cards. Real-
time priority mode allows the ASIO drivers to take precedence for computing resources over all other
tasks that are running on your computer. This can reduce the risk of audio stuttering. This option can be
dangerous though, as it may conict with some VST plug-ins, causing your entire system to freeze. For
that reason, you should only enable this option when absolutely necessary.
PC users note: Some ASIO drivers do not allow settings such as sample rate and latency to be ad-
justed by external applications. If your ASIO driver is one of these cases, then Tracktion’s sample rate
and latency options will have only the current values as choices. In this case you will need to set these
values from the ASIO driver’s own interface by clicking the “show ASIO control panel” button. Be sure
to click the “restart device” button when you are done.
Mac And CoreAudio Drivers
If you are using a Mac and some of your CoreAudio devices are not listed, this may be because they
are not currently connected to the Mac. Close Tracktion, check the connections, and try again.
A good way to check if a CoreAudio device is properly connected to your computer, is to launch the
“AudioMidi Setup” Utility and make sure that the device in question is available as a hardware choice.
Input Device Properties
When an audio input device is selected, its various conguration options will be displayed in the
properties panel (Fig. 2.1.2).
Treat as stereo pair: You can opt to have Tracktion combine two mono audio inputs into a single ste-
reo pair. When disabled, the two channels will appear as two mono devices; when enabled, they will
appear as one stereo device. The les created when recording through mono input devices, will be
mono. Audio recorded to a stereo input will likewise produce stereo les.
