PERFORMANCE SETTINGS

48kHz <-> 44kHz

Describes how VirtualDJ will interpolate between the 48kHz and 44.1kHz sample rates.
Choosing “Basic Interpolation” will save some system resources and could improve
performance. For better q uality interpolation, choose “Lowpass Filter”. 11 taps is the best
q uality/CPU ratio.

NOTE: Most commercially
available music is recorded at
44.1kHz (including MP3s) so it is
a good idea to set your
soundcard’s o utput to 44.1kHz.
T his will prevent your soundcard
from having to interpolate to
different sample rates and will
improve performance. Unless
you have worked with different
sample rates before, the 44.1kHz
setting should be default for your
soundcard)

M aster Tempo

The master tempo is the algorithm controls how VirtualDJ changes the pitch of the song
without changing its tone (“KeyLock featu re”).

The default “Fast” algorithm takes only a small percentage of the CPU power, and produces
good results at pitches in the range of -10% to +10%. For extreme pitching, the fast algorithm
can produce some choppiness. If your computer is fast enough, this can be corrected by using
the Advanced algorithm option. With the Advance option, raising the complexity or
spatialization of the algorithm can quickly overflow the systems CPU’s capabilities.

NOTE: Disable safe-mode for better performance with the Advance algorithm
