Time Stretching and Pitch Shifting are no loss-less proce-
dures - depending on the factor there can occur short de-
lays or other artifacts in the sample. To minimize these
artifacts you have the choice between 3 internal algorithms:
Loops/Songs: Use this mode for factors in the range of
0.9...1.1. This algorithm keeps the original phase even of
stereo material, but it produces more artifacts when using
with large factors.
Loops/Songs/Speech: This mode uses a much more com-
plex algorithm, which needs more time that is calculating.
But it gives in most cases better results when using large
factors. The phase of the material is changed to get a
“smoother” sound. If you were for example dealing with
speech, vocals, or orchestral instruments this would be no
problem. More complex spectrums, such as a mix of differ-
ent instruments or completed mix problems, may develop
problems.
Solo Instruments: This mode uses the same algorithms
as the last one, but uses more of the smoothing compo-
nent. This makes it ideal for solo instrumental sounds like
piano samples or vocals.
Beat Marker-Mode: This is a additional Timestretch Mode.
It is made for pure Drumloops. Basically it works like this:
Through activating the option “Find Beat Marker” the al-
gorithm tries to find and mark Beats in the Audio material.
Only these points will be used for timestretching by mov-
ing the autio material at the markers ahead or back.
Increasing the tempo will superimpose some beats, slow-
ing down generates short pauses between the beats. That
mostly sounds better than the older algorithms.
A threshold value for beat detection can be set by using the
sensitivity control.
Furthermore you are able to set the beat markers manual
before you open the Timestretching dialog.
Just set the markers short of the beats (key: shift + 1 ... 0 )
If a Wave Project is open and visible, you can follow the
process of setting beat markers on the screen.
Test Realtime: This is a new function for the beat marker
mode. Herewith it is easy to test the effect before you let
Music Editor calculate the whole sample.
Irrespective of the tempo, the pitch of the loop can be ad-
justed using the pitch control in the upper left region of
the dialog.
