Pitch Correction effect overview in MainStage
You can use the Pitch Correction effect to fix the pitch of incoming audio signals. Improper intonation is a common problem with vocal tracks, for example. The sonic artifacts that can be introduced by the process are minimal and are almost silent when making moderate corrections.
Pitch correction works by accelerating and slowing down the audio playback speed, matching the input signal (sung vocal) with the correct note pitch. If you try to correct larger intervals, you can create special effects. Natural articulations of the performance, such as breath noises, are preserved.
Any scale can be defined as a pitch reference (technically speaking, this is known as a pitch quantization grid). Improperly intonated notes are corrected in accordance with this scale.
The Pitch Correction effect Scale and Root parameters can be set to the appropriate key, depending on the accuracy of the original intonation.
Note: Polyphonic recordings, such as choirs, and highly percussive signals with prominent noisy portions cannot be corrected to a specific pitch. Despite this, you may want to try the plug-in on some drum sounds, such as toms and congas, because it can deliver interesting results.
To add Pitch Correction to your concert, choose Pitch > Pitch Correction in a channel strip Audio Effect plug-in menu. See Add and remove plug-ins in MainStage.
