Tempo: This control changes the speed independently from the pitch
("timestretching"). The object acts as if it were compressed or stretched on the track.
Tones/BPM: These fields serve for numerical alteration of pitch and speed. Only
MAGIX soundpool files are suitable for numeric entries because they are equipped
with information regarding pitch and speed.
Setup: This button opens a setup dialog, where you can choose between various
pitchshifting and timestretching processes.
• 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.
