- Vibrato: Controls the modulation of pitch in the voice, adding a natural wavering effect that can enhance the emotional quality of the performance;
- Humanize: Introduces variations in pitch and timing to simulate the natural imperfections of human singing, helping to avoid an overly robotic sound;
- Retune speed: Determines how quickly the pitch correction is applied to the vocal signal, affecting whether the correction is smooth and natural or more abrupt and noticeable.
Auto-Tune vs. Melodyne: What is the difference?
Melodyne is another prominent pitch correction and audio editing software developed by Celemony. While Auto-Tune is often associated with a distinct sound effect, Melodyne is more about nuanced, detailed editing and manipulation of audio. It’s notable for the natural sound of its pitch correction.
Key features of Melodyne include:
- Detailed pitch correction: Allows for precise adjustments of individual notes in polyphonic audio (e.g. chords) as well as monophonic sources (e.g. vocal lines);
- Time stretching: Provides control over the timing of audio without affecting pitch; useful for adjusting rhythms and phrasing;
- Note separation: Enables users to separate notes within a chord and adjust them individually;
- Formant shifting: Alters the tonal quality of the voice or instrument without changing the pitch.
The rise of Auto-Tune in singing: From studio tool to iconic sound
Early adoption: Cher’s “Believe” and the birth of the Auto-Tune effect
The first major pop culture moment for Auto-Tune came with Cher’s 1998 hit “Believe.” Producers deliberately pushed the software beyond subtle correction, creating a robotic, wobbling vocal effect that would become synonymous with Auto-Tune.
This bold use of the new technology captured listeners’ attention and marked the beginning of Auto-Tune as a stylistic choice rather than just a pitch correction tool.
