Native Instruments Traktor Kontrol Z2 User Manual

6.2.1 Settings on Mac OS X
On Mac OS X, you can adjust the settings for the Z2 audio interface from within each music
application. In TRAKTOR:
►
Open Preferences > Audio Setup to access the settings for the Z2 audio interface.
There, you can adjust the audio interface settings of the TRAKTOR KONTROL Z2. You have
two settings:
▪ Sample Rate: The Sample Rate is fixed to 48000 Hz for the TRAKTOR KONTROL Z2's
audio interface.
The sample rate defines how many samples are played/recorded per one second of sound.
A higher sample rate results in higher audio quality; however, 44100 Hz (as used for re-
cording audio CDs) is a common setting and absolutely sufficient for most tasks. If your fi-
nal destination is CD you should use this setting or a multiple of it (88200 Hz). For a bet-
ter understanding: 48000 Hz is used by DAT recorders, and for DVD (films) recording.
96000 Hz is typical for DVD, HD DVD, and Blue-ray Disc audio recording. You should be
aware that a higher sample rate also causes higher CPU load.
▪ Latency : Lower the latency value for a quicker response of your computer to TRAKTOR
controller and software actions.
When converting audio information to digital and vice versa, the audio driver needs to store
the data in buffer packages (audio buffers) which are then sent to and processed by the
CPU. The higher the buffer size, the longer it takes for a signal to finally arrive at the out-
put as audio. You might experience this as late response in between hitting a key on a con-
troller which controls music software on your computer, and hearing sound at the output.
This delay is called latency. You should start off with a higher latency value, and gradually
decrease it until you find the perfect balance between playability and audio quality for your
system. If you experience crackling at the audio output, the latency value is very likely to
be too low for your computer’s CPU to cope with, as lower latency values cause a higher
load on the CPU.
