Using Auto-Tune Evo's Powerful Retune Speed Tools For Seamless, Realistic Pitch Correction

With all of the attention these past few years on the Auto-Tune Vocal Effect and its ubiquity in pop culture, it's easy to forget that Auto-Tune was initially designed (and is still most commonly used) for extremely realistic, natural-sounding pitch correction. Combining superb audio quality with powerful, easy-to-use tools, each new generation of Auto-Tune has made it even easier to achieve results so transparent that it's virtually impossible to hear that pitch correction has been applied.

In this month's newsletter, we'd like to highlight some of the key capabilities of Auto-Tune Evo that can ensure that your vocal pitch correction is as natural and realistic as possible.

The Importance of Retune Speed

The single most important Auto-Tune parameter for natural pitch correction is Retune Speed. This is the speed at which the pitches of any out-of-tune notes in the audio are changed to the "right" notes. The goal is to set a Retune Speed that's fast enough to get out-of-tune notes in tune quickly, but not so fast that you can hear it happening in an unnatural way. This is made trickier by the fact that the optimum Retune Speed for any performance depends on such attributes as song tempo, note duration, and vocal style, and can often change from note to note.

Luckily, Auto-Tune Evo includes unique tools in both Automatic and Graphical Modes to make it easy to set optimum Retune Speeds.

Humanize

One situation that can be problematic in Automatic Mode is a performance that includes both very short notes and longer sustained notes. The problem is that in order to get the short notes in tune, you have to set a fast Retune Speed, which would then make any sustained notes sound unnaturally static. Fortunately, Auto-Tune Evo's Automatic Mode Humanize function easily solves this problem.

The Humanize function differentiates between short and sustained notes and lets you apply a slower Retune Speed just to the sustained notes. Thus, the short notes are in tune and the sustained notes still allow the natural variations of the original performance.

Here's how it works:

Start by setting Humanize to 0 and adjusting the Retune Speed until the shortest problem notes in the performance are in tune. At this point, any sustained notes may sound unnaturally static. If so, start advancing the Humanize control. The higher the Humanize setting, the more the Retune Speed is slowed for sustained notes. The goal is to find the point where the sustained notes are also in tune and just enough of the natural variation in the performance is present in the sustained notes to sound natural and realistic. (If you set Humanize too high, any problem sustained notes may not be fully corrected.)

Individual Correction Object Retune Speeds

Prior to Auto-Tune Evo, it was necessary to select a single Graphical Mode Retune Speed that applied to all of your pitch corrections. Your choice was typically picking a Retune Speed that was a "good enough" compromise for an entire track, or painstakingly automating the Retune Speed from phrase to phrase or even note to note (with the attendant cost in time and effort).

With Auto-Tune Evo, we've introduced the ability to set independent Retune Speeds for every individual correction object, whether Line, Curve, or Note. Simply select one or more objects and set the Retune Speed that provides the most natural result. Getting exactly the desired effect for every note of a performance is a quick, simple, and intuitive process.

Of course, in practice you don't need to set an individual Retune Speed for every object. To streamline the process, start by selecting all your audio and setting a Retune Speed that works for the majority of the performance. Then listen to the result and note which notes or phrases could still use improvement. Select those notes or phrases, adjust their Retune Speeds for the most natural result, and you're done.

Default Graphical Retune Speeds

With independent Retune Speeds for each correction object, Auto-Tune Evo includes the time-saving ability to set custom default Retune Speeds for each of the three object types: Lines, Curves and Notes. These are the initial Retune Speed values that are automatically assigned to each newly created object.

To choose your own values, just pay attention to what values you most commonly use for the various objects and set those as defaults in Auto-Tune Evo's Option dialog. Update as necessary.

Of course, these are just a few of the features that make Auto-Tune Evo the most natural-sounding, easy-to-use tool for professional pitch correction. We'll be covering more in a future newsletter.

The Gregory Brothers Win Another One

If it seems like every time you turn around, the Gregory Brothers are winning yet another award for their Auto-Tune the News, well, it's because they are. Earlier this month it was announced that they had won both the Webby Award and the Webby People's Voice Award in the category of Video Remixes/Mashups. Established all the way back in the prehistoric (web-wise) days of 1996, the Webby is the leading international award honoring excellence on the internet. The awards are presented by The International Academy of Digital Arts and Sciences and include two honors in each category, the Webby Award and the People's Voice Award (voted for by the online community at large).

So once again, congratulations to the Gregory Brothers!

That's it for this month. Thanks for reading!
