Chapter 23: Time Shift 131
Threshold The Threshold controls sets the tran-
sient detection threshold from 0.0 dB to
–40.0 dB. Disable transient detection by setting
the Threshold control to Off (turn the knob all
the way to the right). Part of Time Shift’s pro-
cessing relies upon separating “transient” parts
of the selection from “non-transient” parts.
Transient material tends to change its content
quickly in time, as opposed to parts of the sound
which are more sustained. Adjust the Threshold
control or click the Threshold field and type the
desired value.
The default value for Threshold is –6.0 dB. For
highly percussive material, lower the threshold
for better transient detection, especially with
the Rhythmic audio setting. For less percussive
material, and for shifting with the Polyphonic
audio setting, a higher setting can yield better
results. Experiment with this control, especially
when shifting drums and percussive tracks, to
achieve the best results.
Window The Window control sets the analysis
window length for processing audio. You can set
the Window from 6.0 milliseconds to 185.0 mil-
liseconds. Adjust the Window control or click
the Window field and type the desired value.
The Window control is only available when
Polyphonic is selected as the Audio Type.
The default for Window size is 18.0 milliseconds
and works well for many applications, but you
may want to try different Window settings to get
the best results. Try larger window sizes for low
frequency sounds or sounds that do not have
many transients. Try smaller window sizes for
drums and percussion. 37.0 milliseconds tends
to work well for polyphonic instruments such as
piano or guitar. A setting as large as 71.0 milli-
seconds works well for bass guitar. Settings in
the 12 millisecond range work well on drums or
percussion.
Decay Rate The Decay Rate control determines
how much of the decay from a transient is heard
in the processed audio when time stretching.
When time stretching using the Rhythmic set-
ting, the resulting gaps between the transients
are filled in with audio, and Decay Rate deter-
mines how much of this audio is heard by apply-
ing a fade out rate. Decay Rate is only available
when Rhythmic is selected as the Audio Type.
Adjust the Decay Rate up to 100% to hear the au-
dio that is filling the gaps created by the time
stretching with only a slight fade, or adjust
down to 1.0% to completely fade out between the
original transients.
Time Shift Pitch Controls
The Pitch section of Time Shift provides con-
trols for pitch shifting the selected audio. Use
the Pitch control to transpose the pitch from
–24.00 semitones (–2 octaves) to +24.00 semi-
tones (+2 octaves), with fine resolution in cents.
Transpose Displays the transposition amount in
semitones. You can transpose pitch from –24.00
semitones (–2 octaves) to +24.00 semitones (+2
octaves), with fine resolution in cents. Adjust
the Pitch control or click the Transpose field
and type the desired value.
Shift Displays the pitch shift amount as a per-
centage. You can pitch shift from 25.00% (–2 oc-
taves) to +400.00% (+2 octaves). Adjust the
Pitch control or click the Shift field and type the
desired value. The default value is 100% (no
pitch shift).
