User Guide

Overclock – This setting can make your computer run faster (especially on laptops) and

therefore be compatible with lower latencies.

Scratch – Allows for adjustment to how VirtualDJ reacts to scratch motions

Optimize for:

Quality – VirtualDJ will more

accurately represent how a

scratch sounds when moving the

virtual record back and forth

Latency – VirtualDJ reacts as

quickly as possible but might

result in a somewhat more

metallic sound.

Scratch algorithm:

Simple Algorithm – adds no

computational overhead, and will

use a simple interpolation

algorithm to compute the scratch

sound

Enhanced Algorithm – uses an advanced algorithm that mimics the movement

of the needle on the grooves, to obtain the best scratch sound possible. A filter

size of 11 gives the best quality/CPU ratio, producing a very good quality while

keeping a low computational overhead.

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 quality interpolation, choose “Lowpass Filter”. 11 taps is the best

quality/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 output to 44.1kHz. This 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)
