Time Shift Audio Controls
The Audio section of Time Shift provides con-
trols for specifying the type of audio you want to
process and gain attenuation of the processed
signal to avoid clipping.
Mode
The Audio Mode pop-up menu determines the
following types of TCE and pitch shift algorithm
for processing audio:
Monophonic
Select Monophonic for processing
monophonic sounds (such as a vocal melody).
Polyphonic
Select Polyphonic for processing
complex sounds (such as a multipart musical se-
lection).
Rhythmic
Select Rhythmic for processing per-
cussive sounds (such as a mix or drum loop).
Varispeed
Select Varispeed to link time and
pitch change for tape-like pitch and speed
change effects, and post production workflows.
Range
The Audio Range pop-up menu determines the
following frequency ranges for analysis:
Low
For low-range material, such as a bass gui-
tar, select Low.
Mid
For mid-range material, such as male vo-
cals, select Mid. In Monophonic mode, Mid is
the default setting and is usually matches the
range of most monophonic material.
High
For material with a high fundamental fre-
quency such as female vocals, select high.
Wide
For more complex material that covers a
broad frequency spectrum, select Wide. In Poly-
phonic mode, Wide is the default setting and is
usually best for all material when using the
Polyphonic audio type.
Gain
The Audio Gain control attenuates the input
level to avoid clipping. Adjust the Gain control
from 0.0 dB to –6.0 dB to avoid clipping in the
processed signal.
Clip Indicator
The Clip indicator indicates clipping in the pro-
cessed signal. When using time compression or
pitch shifting above the original pitch, it is pos-
sible for clipping to occur. The Clip indicator
lights when the processed signal is clipping. If
the processed signal clips, undo the AudioSuite
process and attenuate the input gain using the
Gain control. Then, re-process the selection.
Time Shift plug-in, Audio section
Rhythmic mode uses transient analysis for
time shifting. If you select audio with no ap-
parent transients, or set the Transient
Threshold control to a setting above any de-
tected transients, Time Shift assumes a “vir-
tual-transient” every three seconds to be
able to process the file. Consequently, the
file should be 20 bpm or higher (one beat ev-
ery three seconds) to achieve desirable re-
sults. For material that has no apparent
transients, use Monophonic or Polyphonic
mode.
The range pop-up menu is unavailable in
Rhythmic mode and Varispeed mode.
