CHAPTER 6 146
Applying Stereo, Pitch, and Delay Effects
Using the Pitch Correction effect (Edit View only)
The Pitch Correction effect provides two ways to make pitch adjustments for vocals or solo
instrumentation. Automatic mode analyzes the audio content and automatically corrects
the pitch based on the key you define, without your having to analyze each note. Manual
mode creates a pitch profile that you can adjust note-by-note. You can even over-correct
vocals to create robotic-sounding effects.
The Pitch Correction effect detects the pitch of the source audio and measures the periodic
cycle of the waveform to determine its pitch. The effect can be used on audio that contains
a periodic signal (that is, audio with one note at a time, such as for a saxophone, violin, or
vocals). Nonperiodic audio, or periodic audio with a high noise floor, can disrupt the
effect’s ability to detect the incoming pitch, resulting in incomplete pitch correction.
To use the Pitch Correction effect:
1 In Edit View, select an audio range.
2 In the Effects tab of the Organizer window, expand Time/Pitch, and double-click Pitch
Correction.
3 Click the Automatic or Manual tab, and set the desired options.
For more information, search for “Pitch Correct options in Automatic Correction
Mode” or “Pitch Correction options in Manual Mode” in Help.
Using the Stretch effect
The Stretch effect lets you change the pitch of an audio signal, the tempo, or both. For
example, you can use the effect to transpose a song to a higher key without changing the
tempo, or you can use it to slow down a passage without changing the pitch. You can also
vary pitch and tempo over the length of the audio, giving the effect of raising and lowering
pitch or slowing down and speeding up the tempo.
To use the Stretch effect:
1 Select an audio range (Edit View) or track (Multitrack View).
2 In the Effects tab of the Organizer window, expand Time/Pitch, and double-click Stretch.
3 Set the desired options.
For more information, search for “Stretch options” in Help.
