This is the defining feature introduced in Auto-Tune 8 and perfected in later versions.
Unlike Antares Auto-Tune (launched in ‘97) or Waves Tune, the “81” here refers to the characteristic resonance peak around 8.1kHz that the analog-modeled detection circuit allegedly uses.

When used as a corrective tool, Autotune81 excels. The "Retune Speed" knob behaves differently than classic units. At high speeds (near 0 ms), you get the classic "T-Pain" effect. However, at medium settings (20-40 ms), the plugin becomes nearly invisible.

The result was a take that sounded like a perfect human performance, not a robot mimicking one. As of 2025, it remains one of the
Unlike modern AI tools that auto-detect scales, Autotune81 usually requires manual input. Set your Key (e.g., Cm) and Scale (Major/Minor/Pentatonic). Pro tip: Use the "Chromatic" scale if the vocalist is very experimental, but locking the scale eliminates 80% of wrong notes automatically.
