The Sample Editor
When you click Auto Adjust, the following happens:
• If you created a loop by defining a selection range in a longer
audio file, the snap point (S symbol) will be moved to the loop
start.
• In the waveform, vertical lines will be displayed. The thick lines
should match the bar positions and the thin lines the beat po-
sitions. You can adjust these lines by means of the Manual
Adjust tool, see below.
• In the Definition tab the Manual Adjust tool will be activated
(see “Manually adjusting grid and tempo of your audio” on
page 250).
• In the Playback tab the Straighten Up button will be switched
on (see “About the Straighten Up mode” on page 249).
5. Open the Playback tab to select an algorithm that
should be applied on realtime playback.
In this pop-up you can find various options that govern the
audio quality of the realtime time-stretching. There are pre-
sets for common types of audio material and an Advanced
option where you can manually set warp parameters:
Option Description
Drums This mode is best for percussive sounds, because it will not
change the timing of your audio. Using this option for pitched
audio will lead to noticeable artefacts. In this case, you can try
the Mix mode.
Plucked This should be used for audio with transients and a relatively sta-
ble spectral sound character (e.g. plucked instruments).
Pads Use this mode for pitched audio with slower rhythmics and a
stable spectral sound character. This will minimize sound arte-
facts, but the rhythmic accuracy will not be preserved.
Vocals This mode was optimized for slower signals with transients and
a prominent tonal character (e.g. vocals).
Mix This mode will preserve the rhythm and minimize the artefacts
for pitched material which does not meet the above criteria (i.e.
with a less homogenous sound character).
This will be selected by default for audio that is not categorized.
Advanced This allows for a manual tweaking of the time-stretching param-
eters. By default, the settings that are shown when you open the
dialog are those of the last used preset (except if the Solo mode
was selected, see below). The Advanced settings are described
in more detail below this table.
Solo This mode will preserve the formants of the audio. It should only
be used for monophonic material (solo woodwind/brass instru-
ments or solo vocals, monophonic synths or string instruments
that do not play harmonies).
