Audio Plug-Ins Guide130
The Formant section is only available when
Monophonic is selected as the Audio Type. The
Formant section provides a single control for
transposing the formants of the selected audio
by –24.00 semitones (–2 octaves) to +24.00
semitones (+2 octaves), with fine resolution in
cents. Adjust the Formant Shift control or click
the Shift field and type the desired value.
Time Shift Transient Controls
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
The follow button enables an envelope
follower that simulates the original acoustics of
the audio being stretched. Click the Follow but-
ton to enable or disable envelope following. Fol-
low is only available when Polyphonic is se-
lected as the Audio Type.
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 charac-
teristic sound or timbre. When pitch shifting
audio, the formant shape is shifted with the
rest of the material, which can result in an
unnatural sound. Keeping this shape con-
stant is critical to formant correct pitch
shifting and achieving a natural sounding
result.
