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.
Locate the desired audio and press the Track
Pitch button. (If you are using Auto-Tune Evo’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.
Next, start playback of the audio. A graphic
representation of the pitch will be drawn to the
display as the audio plays. When all of the audio
you want to correct has played, stop playback.
Note that Auto-Tune will remain in Track Pitch
mode (the button will continue to flash). If you
are using the Host Clock and want to track the
pitch of audio elsewhere in your track, simply
use your host’s transport controls to move to
that audio and start playback again. Auto-Tune
will continue tracking pitch at that point. When
you have tracked all of the audio you want to
correct, click the Track Pitch button again. You
will exit Track Pitch mode and, if you have Auto-
Scroll enabled (as described in the Pitch Graph
Display section below), the Pitch Graph will
automatically scale in such a way as to include
all of the tracked audio. If you have not enabled
Auto-Scroll, no scaling will occur.
NOTE: If you are using Auto-Tune
Evo’s Internal Clock (because your
host does not provide valid clock
information), you will not be able to navigate
around your audio while tracking as described
above. In that case you should either track all of
the audio at once, or track an individual section,
then correct it and bounce the changes (or use
a destructive editor if available) and then move
on to the next section.
ANOTHER NOTE: If the length of the
audio to be processed exceeds the
currently set size of the buffer as set
in the Options dialog (or your start point lies
beyond the current buffer area), tracking will stop
when the buffer is full and a warning message
will appear notifying you of that fact. If this
happens, increase the buffer size as necessary.
YET ANOTHER NOTE: Be cautious
about changing the Tracking value (in
the Options dialog) after performing
the Track Pitch function. Auto-Tune Evo uses
the Tracking setting during both the Track Pitch
function and while correcting pitch. Changing
the Tracking setting after Tracking Pitch, but
before correcting, may result in unpredictable
pitch modifications or strange (though possibly
interesting) artifacts.
Correct Pitch
In versions of Auto-Tune prior to Auto-Tune 5,
after creating correction objects, you would
have to press the Correct Pitch button in order
to put Auto-Tune into correction mode. As a
result, the Auto-Tune window always had to be
open in order to use Graphical Mode. Well, no
longer. Now, simply create your corrections and
play. Essentially, anytime you are not tracking
pitch, Auto-Tune Evo will be correcting. It is this
basic change that allows you to use multiple
instances of Auto-Tune Evo simultaneously in
Graphical Mode without having to have their
windows visible.
NOTE: The ability to use multiple
instances of Auto-Tune Evo
simultaneously in Graphical Mode
without having to have their windows visible is
only available for hosts that provide valid time
information. See the Clock Source section above
for details.
