When performing time compression, Auto-
Tune 8 needs to process the audio at faster
than real time. At the limit of 10:1, audio must
be processed at ten times it’s normal rate.
Our tests have shown that computers that
meet our published system requirements
can accomplish this in most cases, but it’s
important to keep in mind that if your session
is particularly complex, with many tracks and
lots of other potentially processor-hungry
plug-ins all running at once, even the fastest
computer may have trouble keeping up.
To alert you to any data access problems, the
Data File Status indicator will light red anytime
Auto-Tune 8 is unable to read data from its
disk file in the time available. If this happens,
you should consider the following options:
•
Listen carefully to the point in your audio
where the Data File Status indicator lights
red. Very much like a VU meter’s clip light,
not every instance will result in an audible
problem. If you can’t hear anything wrong,
you can safely ignore it.
•
Decrease the amount of time compression
by a tiny bit. If you’re right on the edge of
your computer’s capability, an extremely
small change can eliminate the problem.
•
Temporarily simplify your session (mute
other tracks, bypass other plug-ins) and
render or bounce or your time edits to a
new track.
•
Since data access depends on everything
going on at any particular time in your
session, for cases that are on the edge of
your computer’s capability, it’s possible that
the Data File Status indicator might light red
on one pass, but not on another. It’s always
worthwhile just playing the track again to
see if Data File Status red indication was a
one-time anomaly.
•
Buy a faster computer. If you’ve been
looking for an excuse to upgrade, the Data
File Status indicator may be your ticket to
that hot new Mac or PC you lust after.
Track Pitch + Time
The process of tracking pitch
and time is very much like
that of simply tracking pitch
alone. The only dierence
is that in addition to normal
pitch tracking, Auto-Tune 8 also makes a
recording of the actual audio to be processed.
To track pitch and time, locate the desired
audio and press the Track Pitch + Time button.
(If you are using Auto-Tune 8’s Internal clock,
you may (depending on your host) need
to click the Reset button to reset the clock
position to :: ) The Track Pitch + Time
button will flash blue and red to indicate that
Auto-Tune is in Track Pitch + Time mode.
Next, start playback of the audio. A graphic
representation of the pitch and its amplitude
envelope will be drawn to the display as the
audio plays. When all of the audio you want
to correct has played, stop playback. You
will exit Track Pitch + Time mode and, if you
have Auto-Scroll enabled, 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.
In addition, the central horizontal axis of the
Envelope Display will turn red to indicate the
range of audio that has been recorded and is
available for time shifting.
NOTE: If you are using Auto-Tune
8’s Internal Clock, after stopping
playback in your host, you must click
the clock Reset button to stop Auto-Tune 8’s
transport and return you to the beginning of
your tracked region.
ANOTHER NOTE: Although tracking
time does not involve the Buer
Size setting in the Options dialog,
tracking pitch (which happens simultaneously)
does. Consequently, if the length of the audio
to be processed exceeds the currently set
Buer Size (or your start point lies beyond the
current buer area), tracking of both pitch
and time will stop when the buer is full and a
warning message will appear notifying you of
that fact. If this happens, increase the buer
size as necessary.
