Auto-Tune Realtime Advanced

Auto-Tune Realtime Advanced compares a detected monophonic pitch against an allowed set of notes and moves it toward a target. Choosing an appropriate Input Type and the song's key and scale is therefore more important than simply turning up correction. It is intended for isolated voices and non-chordal instruments, not complete mixes or harmonically complex ensembles.

Its main creative distinction is between correction speed and preservation of expression. Retune Speed sets the response, Flex-Tune leaves more intentional movement between notes, and Humanize relaxes the treatment of sustained passages. Classic Mode offers the earlier Auto-Tune 5 character and disables Flex-Tune. Natural Vibrato modifies vibrato already in the performance; the separate Create Vibrato section synthesizes new movement.

Begin in Basic View, establish the note set, and listen to both short notes and held vowels. Move to Advanced View when an incorrect target requires scale editing, a melody should follow MIDI, or vibrato needs detailed shaping. Returning to Basic View hides those advanced settings without disabling their sound.

Detection and target notes

• Input Type selects Soprano, Alto/Tenor, Low Male, or Instrument detection. Match the source before adjusting correction.
• Key / Scale define the allowed pitch set. Chromatic permits all twelve semitones; it cannot determine which of two neighboring notes the singer intended.
• Detune changes the reference from A = 440 Hz, with an adjustment of −100 to +100 cents. Preferences can display the offset in cents or hertz.
• Tracking changes how strictly periodic the waveform must be. Start at the documented default of 50; higher settings accommodate breathier input, while lower settings can help reject irregularities.

Correction and expression

• Retune Speed governs how quickly notes are corrected. Zero produces immediate changes and suppresses vibrato; slower settings retain more pitch movement.
• Flex-Tune narrows correction to the area near target notes as it increases. Classic Mode recalls the Auto-Tune 5 response and disables this control.
• Humanize slows correction during sustained portions without giving up the fast response needed for short notes. Establish Retune Speed first, then add Humanize.
• Natural Vibrato increases or reduces existing vibrato. Pitch Display, Pitch Change Meter, and the keyboard distinguish corrected output, correction amount, and detected input pitch.

Advanced View

• Keyboard On / Bypass / Remove either enables a target, passes nearby input uncorrected, or redirects it to another allowed note. Keyboard edits are octave-specific; Edit Scale Display changes every octave. Set Major / Set Minor, Set All, Bypass All, and Remove All accelerate scale construction.
• Targeting Ignores Vibrato helps prevent a wide vibrato from alternating between unintended target notes.
• Create Vibrato offers Shape and Rate, Onset Delay before vibrato begins, Onset Rate for its buildup, and Variation for note-to-note irregularity. Separate Pitch, Amplitude, and Formant Amount controls determine which aspects fluctuate.
• MIDI Target Notes follows currently held MIDI notes; with none held, correction stops. Learn Scale builds an allowed-note set from MIDI. All Octaves determines whether incoming notes apply globally or only to their played octaves.
• Settings / Preferences provide Auto-Key reception, reference display, MIDI input channel, and MIDI parameter assignments. MIDI routing itself must be configured in the host.
