Automatic options
The Automatic tab of the Pitch Correction dialog box provides the following options:
Specifies which channel to use for source audio. The Pitch Correction effect analyzes and profiles
Reference Channel
just the periodic signal of the channel you choose, but it applies the pitch correction equally to both channels.
Specifies the standard pitch calibration for the source audio. In Western music, standard pitch
Calibration
calibration is A4 = 440 Hz. Source audio, however, may have been recorded where the calibration was slightly
different. In this case, you can raise or lower the Hz value from 430 to 450.
Sets the FFT (Fast Fourier Transform) size, or the size of the pieces of data that the effect processes. In
FFT Size
general, use smaller values for correcting higher frequencies. For voices, a setting of 2048 or 4096 sounds most
natural, and a setting of 1024 creates robotic effects.
Specifies the scale type that best suits the material. You can choose from Major, Minor, or Chromatic.
Scale
Chromatic works best if only a slight correction is needed to "pull" the pitch of any tone to the closest chromatic note.
Major and Minor allow for larger corrections, such as where the source audio is more than a single half-step interval
off pitch from the desired musical scale.
Sets the key for the corrected material. This option is available only if Scale is set to Major or Minor (since the
Key
Chromatic scale includes all 12 tones and isn't key-specific). Typically, the key is the same as the one intended for the
source audio.
Governs how quickly Adobe Audition corrects the pitch toward the scale tone. Faster settings are usually best
Attack
for audio made up of short notes, such as a fast passage played by a trumpet. An extremely fast attack can also achieve
a robotic quality. Slower settings result in more natural-sounding correction on longer sustaining notes, such as a
vocal line where the singer holds notes and adds vibrato. Because source material can change throughout a musical
performance, you can get the most natural-sounding results by correcting short pieces (such as individual phrases)
at a time.
Defines a threshold beyond which a note isn't corrected. Sensitivity is measured in cents, and there are
Sensitivity
100 cents per semitone. For example, a Sensitivity value of 50 cents means a note must be within 50 cents (half a
semitone) of the target scale tone before it is corrected automatically.
Displays the correction as it occurs during preview, showing you when flat tones are raised and

sharp tones are lowered, and by how much.
