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.
Recommended for:
• Orchestra instruments: String instruments, wind instruments, etc.
• Speech, single voice, and multi-voice sections
• Speech with background noise like video sound, etc.
• Synthesizer areas, guitars, etc.
Not suited for:
• Stereo mix
• Drum loops, percussion
CPU strain: very high
Beat marker slicing
This mode focuses on customizing drum loops, but can also be used on other material
like monophonic bass runs or sequencer lines. The algorithm splits the material into
individual components, individual notes, or beats, which are then selected via the beat
marker.
These "snippets" are then compiled into the new temporal measure. If the tempo is
increased, then individual beats begin overlapping; if it is slowed down, then short
pauses between the beats become audible.
