InTune-Performer: Vocal Pitch Correction Plugin by Antelope Audio

Antelope Audio says the main objective in developing InTune-Performer was pitch correction without distorting the character of the voice. Its pitch-processing engine moves the pitch toward the target note while preserving the original timbral features of the voice.

The developer notes that in most configurations, short of the most extreme settings, it is hard to hear that correction has been applied. That makes it relevant for both real-time performance and studio recording.

The main controls are Correction enable, Delay, Strength, Key and Scale. Delay sets the time between the start and completion of pitch correction, which helps reduce the jumps associated with heavy-handed correction. Its fully clockwise setting is the most subtle. Strength sets the amount of correction applied, from zero to 100 percent corrected.

The plugin is inserted on the vocal track. A Proline mode follows a master melody from a sidechain track, so you can correct a vocal to a reference line instead of setting a key and scale manually.
