NOTE: As the various host developers
are constantly updating their
applications’ functionality, it may be
necessary to update to the latest version of
your host to use Host Clock Mode.
Time Display Mode
Use this control to display the timeline labels in
the Pitch Graph Display in either bars and beats
(as defined by your host’s tempo), or absolute
time in hours, minutes, seconds, and fractions
of seconds.
NOTE: If you select Bars + Beats, you
will only see the timeline labels for
regions where you have tracked pitch
or pitch and time.
ANOTHER NOTE: If after tracking pitch
or pitch and time, you change the
time signature in your host anywhere
in the range of tracked audio, you will need to
re-track the audio in order for the changed time
signature to be reflected by the Bars + Beats
display. For that reason, you should, whenever
possible, set your time signatures before
tracking pitch or pitch and time.
This control also sets the format for the Cursor
Time Position display.
Sample Rate Display
This display indicates the sample rate of the
current audio file as reported to Auto-Tune 7 by
the host application.
NOTE: Auto-Tune 7 is high sample
rate compatible. If your host
application and audio hardware are
capable of dealing with up to 192 kHz files (96
KHz files in Pro Tools HD Accel systems), Auto-
Tune 7 will process them correctly. However,
it’s important to remember that high sample
rate files require substantially more DSP
power than 44.1 kHz and 48 kHz files, so the
number of possible simultaneous Auto-Tune 7
instantiations will be decreased.
ANOTHER NOTE: If you are using
external A/D converters with
independently selectable sample
rates, it can be possible to establish a mismatch
between the actual conversion sample rate and
what the host application thinks is the sample
rate. If this happens, Auto-Tune 7 will appear
to be correcting pitch to the “wrong” key. If
this appears to be happening, check to be sure
that your converter sample rate and your host
application sample rate (as displayed by Auto-
Tune 7) match.
Pitch Tracking and Correction Objects
Track Pitch
The Track Pitch function is used
to detect the pitch of the audio
to be processed so that it can
be displayed on the Pitch Graph
Display.
NOTE: If you will only be correcting
the pitch of your vocal and will not be
editing the time, you need only use
the Track Pitch function as described below.
However, if you will also be editing the time,
you should instead use the Track Pitch + Time
function as described in the Graphical Mode
Time Controls section later in this chapter.
IMPORTANT NOTE: You should always
start tracking pitch in an area of
silence before the audio you want
to correct, or from the very start of the track.
Starting tracking in the middle of audio will
typically result in an artifact.
To track pitch, locate the desired audio and
press the Track Pitch button. (If you are using
Auto-Tune 7’s Internal clock (see below) you
may (depending on your host) need to click
the Reset button to reset the clock position to
00:00:0.) The Track Pitch button will flash blue
and red to indicate that Auto-Tune is in Track
Pitch mode.
