System information
Setting Description
ėlastique The élastique method uses technology from zplane.development,
and provides enhanced real-time time stretching and pitch-shifting
capabilities.
The élastique method also allows you to preserve and shift a clip's
formants, which are the characteristic resonant frequencies of a
sound.
1. Choose a setting from the Stretch attributes drop-down list
to choose the stretching method best suited to your media:
n Pro – Provides the highest quality stretching but
requires more RAM usage and CPU power.
n Efficient – Uses fewer resources while still producing
great time-stretching quality for polyphonic audio.
n Soloist (Monophonic) or Soloist (Speech) – Provide
good quality for monophonic audio with little effect
on system resources.
2. Type the desired event length in the New length box.
The event's original length is displayed for reference in the
Original length box.
3. Type the desired pitch shift (in semitones) in the Pitch change
box.
If you want to change the event length without changing
pitch, type 0 in the box.
If you want the pitch to be determined by the new event
tempo, select the Lock to stretch box. For example, doubling
an event's tempo will raise its pitch by one octave.
4. If the élastique Pro mode is selected in the Stretch attributes
drop-down list, you can type a value in the Formant shift box
to adjust the event's formants.
This option is only available when the Preserve formants
check box is selected.
Formant shifting can be used to deepen the tone of a vocal
performance without changing the pitch.
The formant shift amount represents the number of
semitones to shift the timbre in addition to the offset required
to compensate for any pitch shifting. For example, a setting
of 0.000 applies formant correction with no additional
shifting, while a setting of -7.000 will apply formant
correction and deepen a sound by 7 semitones.
