 Standard: Timestretching and pitchshifting in standard quality. The method is
suitable for audio material without a pronounced beat. Existing beat markers
are evaluated to improve audio quality.
 Smoothed: Timestretching and pitchshifting for audio material without
impulse-like components. The method is suitable for several voice orchestra
instruments, surfaces, speech and singing. Beat markers will not be evaluated.
A complicated algorithm is used here, which results in a higher processor
load. Material can also be edited using very large factors (0.2...50), without
large artifacts. For this, material will be somewhat "smoothed", which will be
manifested in a softer sound and an altered phase length. This smoothing is
hardly audible, e.g. with speech, singing, or solo instrumentation. For complex
spectra, such as mixes of different instruments and finished mixes, this can
lead to problems.
 Beat marker slicing: Beat-synchronous timestretching and pitchshifting via
splitting and temporal repositioning. Exactly set beat markers are required at
the beats or transients. Markers can be generated in realtime (automatically) or
read out from the source file, as long as they are available (patched). A patch
tool is available in MAGIX Music Editor which lets the user set own markers.
The algorithm is suitable for rhythmic material that can be divided into
individual beats or notes. For this, the levels before and after the individual
notes or beats should be low.
 Beat marker stretching: Beat-synchronized timestretching and pitchshifting in
high audio quality. The material is stretched between beat markers positions
so that the impacts or attacks at the beat markers positions are not impaired
by stretching. The markers can be generated in real time from the audio
material (automatically), provided they are present (patched). The method is
suitable for rhythmic material which is not separated into individual beats or
notes because the beats or notes overlap.
 Beat marker stretching (smoothed): Beat-synchronous timestretching and
pitchshifting in high audio quality, even with extreme timestretching. Beat
markers are used at the beats or transients. The markers can be generated in
real time from the audio material (automatically), or read out from the wave file,
provided they are present (patched). The method is suitable for rhythmic
material which is not separated into individual beats or notes because the
beats or notes overlap. This method results in relatively high CPU loads, and
should be used carefully on less powerful systems.
 Universal HQ: Universal method timestretching and pitchshifting in very high
audio quality. Suitable for all types of audio material. Existing beat markers are
evaluated to improve audio quality. This method requires so much processing
time, that a realtime application is recommended only in exceptional situations.
For this reason, we recommend to use the apply function.
 Monophonic voice: Time-stretching and pitch-shifting for vocal solos, speech
or solo instruments. The material may contain no background noise, and even
strong reverb can reduce the usefulness of this method. With suitable material
