What Is Autotune and How Does It Work?

Autotune is a pitch correction tool that adjusts your voice to the closest musical note.
It can be used in two main ways:

• Subtle correction (used in pop, R&B, and gospel)
• Heavy processing for stylistic effects (like trap and melodic rap)

It listens to the input (your voice), then shifts the pitch to match the key and scale you’ve chosen.

Basic Settings for Beginners

If you’re just getting started, here’s what you need to know:

• Key & Scale: Make sure it matches your instrumental. This is step zero.
• Retune Speed:
  • Slow (20ms–50ms) = More natural sound
  • Fast (0ms–10ms) = Robotic or stylized sound
• Humanize: Helps preserve the natural fluctuations in your voice
• Flex Tune (or similar): Controls how aggressively autotune reacts
• Formant Control (if available): Keeps your vocal tone intact when pitch shifting

Pro tip: Even if you’re doing melodic rap, try tweaking Retune Speed and Humanize until it matches your emotion and flow.

Tips to Sound More Natural or More Stylized

Want more Travis or more T-Pain? Here’s how to adjust:

To Sound More Natural:

• Use a slower retune speed (15ms–40ms)
• Add humanize if the plugin supports it
• Focus on clean takes — autotune works best when the performance is already solid
• Avoid stacking too many FX before autotune

To Get a Stylized Sound:

• Use 0ms retune speed
• Don’t be afraid to exaggerate the effect — make it part of the aesthetic
• Try layering harmonies or doubling vocals with different retune speeds
• Use formant shifting to add a surreal quality to your voice
