Audio processing and functions
Time stretch algorithm
280
Standard – Mix
This mode preserves the rhythm and minimizes the artifacts for pitched
material that does not meet the above criteria (i.
e. with a less homogenous
sound character).
This preset is selected by default for audio that is not categorized.
Standard – Custom
This preset allows you to manually tweak the time stretching parameters (see
below). By default, the settings that are shown when you open the dialog are
those of the last preset used (except if the Solo preset has been selected, see
below).
Standard – Solo
This mode preserves the timbre of the audio. Only use it for monophonic
material (solo woodwind/brass instruments or solo vocals, monophonic
synths or string instruments that do not play harmonies).
If you select the “Standard – Custom” option, a dialog opens where you can
manually adjust the three parameters that govern the sound quality of the time
stretching:
Grain size
The standard time-stretching algorithm splits the audio into small pieces
called “grains”. This parameter determines the size of the grains. For material
with many transients, use low grain size values for best results.
Overlap
Overlap is the percentage of the whole grain that will overlap with other
grains. Use higher values for material with a stable sound character.
Variance
Variance is also a percentage of the whole length of the grains, and sets a
variation in positioning so that the overlapping area sounds smooth. A
Variance setting of 0 will produce a sound akin to time stretching used in early
samplers, whereas higher settings produce more (rhythmic) “smearing”
effects but less audio artifacts.
