    Chapter 1: Getting Started If you are new to Auto-Tune, we encourage you to read this manual and work through the tutorials in Chapter 4. It’s the quickest way to become familiar with what Auto-Tune 5 does and how it does it. If you are upgrading from a previous version of Auto-Tune, you will find that most of what you’re already doing will continue to work in Auto-Tune 5, only better.

Calculating the pitch of How Auto-Tune 5 corrects pitch a periodic waveform is a straightforward process.

    Automatic Mode Auto-Tune 5’s Automatic Mode works by Scales The heart of Automatic Mode pitch correction continuously tracking the pitch of an input is the Scale. Auto-Tune 5 lets you choose sound and comparing it to a user-defined from major, minor, chromatic or 26 historical, scale.

This is set with the vocal phrase that contains both vibrato and Retune Speed control (see Chapter 3 for more expressive gestures.

  • Page 19 The Graphical Mode also includes the Envelope Graph, which displays the amplitude (loudness) envelope of the sound whose pitch is shown in the Pitch Graph. The horizontal scale of this graph will either 1) show the envelope of the entire extent of the pitch- detected sound or 2) align with the horizontal scale and position of the Pitch Graph above it.

  • Page 31 When this function is ”On,“ Auto-Tune 5 uses the impressively named Stochastic Optimal Linear Estimation Theory to attempt to recognize vibrato and differentiate between it and intended note changes. Our testing has shown that it works a lot of the time — but not always (it depends a great deal on the actual performance).
  • Page 32 Nonetheless, one situation that could previously send you to Graphical Mode was a performance that included both very fast notes and longer sustained notes. The problem was that in order to get the fast notes in tune, you’d have to set a fast Retune Speed, which would then make any sustained notes sound unnaturally static.
  • Page 33 RATE Sets the rate of the vibrato over a range of 0.1 Hz to 10 Hz. The default Rate setting is 5.5 Hz. Double-clicking or Command (Mac)/Control (PC) clicking the Rate knob will reset it to that value. VARIATION Sets the amount of random variation that will be applied to the Rate and Amount parameters on a note to note basis.
  • Page 34 As mentioned above, NOTE: although we perceive vibrato primarily as a variation in pitch, in most cases there is also matching (though more subtle) variations in amplitude and timbre. Setting Auto-Tune 5’s Retune Speed to 0 will remove an existing vibrato’s pitch variation, but the amplitude and timbral variation will remain.
