Audio
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
type of TCE and pitch shift algorithm for pro-
cessing audio: Monophonic, Polyphonic,
Rhythmic, or Varispeed.
Monophonic Use for processing monophonic
sounds (such as a vocal melody).
Polyphonic Use for processing complex sounds
(such as a multipart musical selection).
Rhythmic Use for processing percussive sounds
(such as a mix or drum loop).
Varispeed Use 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
frequency range for analysis: Low, Mid, High, or
Wide. For low-range material, such as a bass gui-
tar, select Low. For mid-range material, such as
male vocals, select Mid. The high range control
is for material with a high fundamental fre-
quency, such as female vocals. For more com-
plex material that covers a broad frequency
spectrum, select Wide.
In Polyphonic mode, Wide is the default setting
and is usually best for all material when using
the Polyphonic audio type.
In Monophonic mode, Mid is the default setting
and is usually matches the range of most mono-
phonic material.
The range pop-up menu is unavailable in Rhyth-
mic mode and Varispeed mode.
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.
Level Indicator
The Level indicator displays the level of the out-
put signal using a plasma LED, which uses the
full range of plasma level metering colors.
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.
