the creation of harmony voices.
Logic Studio includes the following Pitch effects:
 “Pitch Correction” on page 151
 “Pitch Shifter II” on page 155
 “Vocal Transformer” on page 156
Pitch Correction
You can use the Pitch Correction plug-in to correct the pitch of audio tracks. Improper
intonation is a common problem with vocal tracks, for example. The sonic artifacts that
can be introduced by the process are minimal and can barely be heard, as long as your
corrections are moderate. The correction works by accelerating and slowing down the
playback speed, ensuring that the input signal (sung vocal) always matches the correct
note pitch. If you use the algorithm to correct larger intervals, you can create special
effects. The natural articulations of the performance, such as breath, are preserved. Any
scale can be defined as a pitch quantization grid. Improperly intonated notes will be
corrected in accordance with this grid.
Note: Polyphonic recordings (choirs on one track) and highly percussive signals, with
prominent noisy portions, can’t be corrected to a specific pitch. Despite this, feel free to
try the plug-in on drum tracks!
