The default settings of this parameter aim at stable and trou-
ble-free system performance. However, if you are using a fast
computer and good audio hardware, you can diminish the
latency of your system by experimenting with the Granulation
parameter: A low granulation value will result in better sound-
ing playback of volume changes. But if granulation is set too
low, the computer and operating system might not be able to
perform all tasks “in time”, resulting in short dropouts and
unwanted noises. So for proper optimization, it is necessary to
find a good balance between low granulation and safe audio
playback performance. Proceed as described below:
•
Set up LADS as described above. Take your time!
•
Lower the granulation value in steps of approximately 50
milliseconds.
•
Quit LADS, start Logic fun and test the audio playback.
•
If all audio is played backwithout problems, you can try to
further diminish the granulation value. Don’t forget the
previous value.
•
If dropouts or other problems occur during audio playback,
choose a higher granulation value again.
Up-to-date PCI sound cards, like the Sound Blaster Live! allow a granulation of
approximately 200 milliseconds. For professional PCI cards an even shorter value
may work. Please note that the Granulation parameter is not available for Direct-
Sound drivers.
Removing Settings from LADS
If you have changed settings in the Logic Audio Device Setup
(LADS), you can remove your changes. By clicking on Remove
all you can remove all settings made. You can restore the system
to as it was right after Logic fun’s installation by clicking on Full
Rescan.
