Resampling
Samplers and PCM synthesizers transpose samples during this
procedure. Time factor and pitch are dependent upon each other; the
shorter the audio material, the higher the pitch. This effect is
comparable with changing the play back speed of record players or
tape recorders.
The effect is relatively loss-free, and the sound loss is less than all
timestretching/pitchshifting procedures. If pitch change is justified by
changing the speed (and vice versa), use this algorithm.
When lengthening the audio material by resampling, very small
aliasing effects may occur. The anti-aliasing filter helps correct this.
Alternatively, since this filter creates additional CPU load, it can be
activated for computation and real-time previewing. The filter is also
available for the other algorithms that use internal resampling during
pitchshifting.
Default
"Standard" applies an algorithm which usually delivers very good
results, including factors from 0.9 to 1.1, and operates in phase-
locked mode to maintain the room effect of stereo signals. For drum
loops or other "beat heavy" material, this algorithm is only partially
suitable, since it can change the groove and even fade out or double
beats in rare cases.
Time compression (sample length is reduced) is more successful with
this algorithm than timestretching, i.e. it is better to reduce the longer
sample than vice versa when adjusting two samples to another.
Smoothed
A considerably more complex algorithm is used which requires more
processing time. The material can now also be used on very large
factors (0.2 - 50) without bringing about strong artifacts. The material
is "smoothed", making the sound softer and emitting it at an adjusted
phase level. This smoothing is hardly audible with speech, singing, or
solo instrumentation. Problems may arise with more complex spectra
(sound mixes from various instruments or finished mixes). This
algorithm is not very well suited to drum loops and other material with
strong transients. The groove remains intact, but the attacks are
slurred because of phase shifting. With small corrections (factor ca.
0.9 - 1.1) the setting of the smallest possible smoothing value should
be used.
