Adjust the Formant Shift control or click the
Shift field and type the desired value.
Transient
The Transient section is only available when
Polyphonic or Rhythmic is selected as the Audio
Type, and provides slightly different controls for
each.
When Polyphonic is selected as the Audio Type,
the Transient section provides controls for set-
ting the transient detection threshold and for
adjusting the analysis window length for pro-
cessing audio.
When Rhythmic is selected as the Audio Type,
the Transient section provides controls for set-
ting the transient detection threshold, and for
adjusting the decay rate of the transients in the
processed audio when time stretching.
Follow Enables an envelope follower that simu-
lates the original acoustics of the audio being
stretched. Click the Follow button to enable or
disable envelope following. Follow is only avail-
able when Polyphonic is selected as the Audio
Type.
Threshold Sets the transient detection threshold
from 0.0 dB to –40.0 dB. Disable transient detec-
tion by setting the Threshold control to Off
(turn the knob all the way to the right). Part of
Time Shift’s processing relies upon separating
“transient” parts of the selection from “non-
transient” parts. Transient material tends to
Time Shift plug-in, Formant section
Audio with a fundamental pitch has an
overtone series, or set of higher harmonics.
The strength of these higher harmonics cre-
ates a formant shape, which is apparent if
viewed using a spectrum analyzer. The over-
tone series, or harmonics, have the same
spacing related to the pitch and have the
same general shape regardless of what the
fundamental pitch is. It is this formant
shape that gives the audio its overall char-
acteristic sound or timbre. When pitch
shifting audio, the formant shape is shifted
with the rest of the material, which can re-
sult in an unnatural sound. Keeping this
shape constant is critical to formant correct
pitch shifting and achieving a natural
sounding result.
