What is Auto-Tune? Auto-Tune is an instrument created by Antares Audio Technologies that is widely used in modern music. Its latest version is Auto-Tune Pro. The initial purpose of the program was pitch correction, now it’s very popular also for its quality effect on the vocal that is used in creating rap, pop, hip-hop, and other genre songs.
How lớn use Auto-Tune? Auto-Tune can be used live during the recording process and also in post-recording for editing vocals & pitch correction. It can be used as a VST plugin for different DAW, such as Pro Tools, xúc tích Pro, Ableton, Cubase, và others.
This software can be a powerful instrument for a sound engineer, however, only when you understand all its options & settings, you will know how lớn use Auto-Tune khổng lồ its full potential.
What is Auto-Tune & how does it work?
Auto-Tune allows you to shift the pitch of the vocal to match the needed key automatically. If you know how khổng lồ use Auto-Tune & apply it correctly, you’ll receive the same voice but singing the right notes. By changing some parameters, you also can maximize the famous Auto-Tune sound effect on the voice.
Main ways of using Auto-Tune:
Real-time pitch correction. It can be used during recording sessions or live performances lớn change the pitch of the voice in real-time. Auto-Tune automatically shifts the pitch of the voice khổng lồ the nearest key belonging khổng lồ the specified harmony. This way you can correct the imperfection of the singing instantly & make the artist sound perfectly in harmony with the music.Applying Auto-Tune to the recorded audio. The plug-in can also be used after the recording process is done to correct the vocal. To do it, you have lớn separate a vocal track you want to autotune and apply the plug-in lớn it with the needed settings.Manual pitch correction. An option for manual voice correction is also present in Auto-Tune Pro. If you know how to lớn use Auto-Tune in graph mode, You can apply manual corrections as you would vì chưng using Melodyne studio. This option is needed when you want to gently correct certain parts of the recorded sound wave.Creating the Auto-Tune effect. Some artists, though, use Auto-Tune only for the reason of receiving the Auto-Tune effect on their voice. With the effect on maximum, the voice becomes similar lớn computer-generated sound at the same time still sounding quite human. It also jumps roughly from chú ý to chú ý without the gentle transitions a natural singing would create. These qualities of sound have become quite popular và for some artists, Auto-Tune effect became the feature of their music, the vi xử lý core part of their quality sound by which the audience recognizes them.How to use AutoTune?
Let’s say I am going to lớn apply Auto-Tune right now, what settings will I choose? In what order? How lớn use Auto-Tune? Let’s go through the settings one by one. First, there are General autotune settings that are shown with a basic view option.
1. Choose input type
First, I set input đầu vào type. Remember how khổng lồ use Auto-Tune correctly and apply it only lớn a voice or instrument that produces one pitch at a time, the algorithm won’t work on a polyphony. For input đầu vào type, we have a choice of Soprano, Alto/Tenor, Low Male, Instrument, and Bass Instrument. If it’s an unnaturally high male voice or high female voice we’ll choose soprano. For a medium male or female voice, we choose Alto/Tenor, và so on. We also can use Auto-Tune with instruments, but they should play one lưu ý at a time.
2. Find your Key and Scale
We need to choose the key of the song, it will help the plugin to lớn tune the vocal only to certain keys that belong to lớn this song’s harmony. This will minimize the mistakes.
To choose the Key and the scale, you can use an additional plugin Auto-Key that goes with Auto-Tune Pro. Auto-Key can detect the Key of the tuy vậy using a vocal or accompaniment track. It will not always choose correctly, but if you cannot determine the key of the tuy nhiên yourself, Auto-Key is your best shot.
Another way is lớn use the chromatic scale option. In this case, all the notes will be included & you will be able khổng lồ later delete the notes you don’t need khổng lồ use. We recommend you khổng lồ use Chromatic mode and then choose scale using advanced mode. We will describe it later in this article.
3. Choose between auto and Graph mode
Besides the tự động mode for autotuning, Auto-Tune Pro contains a Graph mode for manual sound correction. This Melodyne-like feature is complicated and powerful, you can correct particular places in the recording the way you like manually. However, how khổng lồ use Auto-Tune for manual voice corrections is the topic for a separate article, so here we’ll be talking about the auto mode in Auto-Tune.
4. Play with Formant và Throat
Formant and throat are the options that were absent in old versions of Auto-Tune, and their presence makes it possible lớn shift the voice to a more distant pitch or transpose the track to a large interval without receiving a chipmunk or other unnatural effects. These options allow adjusting the virtual throat so that it would correspond to lớn the resulting pitch produced by a human. Of course, on the other hand, you can use these options to lớn create an unnatural low or high timbre effect. But in most cases, we don’t use this setting.
5. Don’t change Transpose
Usually, you don’t need lớn change this setting. It’s always better lớn rerecord vocals in a different key. This option helps you transpose your entire track higher or lower. Just select the number of semitones corresponding lớn the transposition interval & the pitch will be shifted in real-time. This also shows how to lớn use Auto-Tune for creating a polyphony of vocals or changing the key of vocals in your song.
6. Use Detune if you have a different reference pitch
How khổng lồ use Auto-Tune for songs tuned lớn another reference key frequency? For this, you can set the reference pitch in the Detune option. In the whole musical world today the reference pitch is 440Hz for the A key. The instruments are usually tuned according lớn this standard. It’s quite probable that you’ll never need to change this parameter.
However, if you come across a tuy nhiên that was recorded with a different reference A, or if you wish khổng lồ create a tuy vậy with different reference middle A frequency, you can easily detune the application setting khổng lồ the old 432Hz reference or other.
7. Set up your Tracking
Tracking represents the Auto-Tune sensitivity. Initially, it’s phối for 50 và you probably won’t need lớn change that. However, if you have a clean studio recording, you may set the value higher, or if there’s a lot of background noise, you might need khổng lồ reduce the value a little.
8. Choose Retune tốc độ for your recording
And this is how to lớn use Auto-Tune for creating a robotic voice. When set lớn 0, it produces the famous “Cher effect” or “T-Pain effect” on the vocal. This effect was first made famous by Cher’s tuy nhiên “Believe”. The corrected vocal switches pitch abruptly, & we hear a robotic sound jumping from one lưu ý to another quickly.
On the other hand, when the retune tốc độ is slowed down (higher values), it makes more gentle corrections with less robotic effect. It’s great if the target is just a slight pitch correction và you don’t mind having a bit of the initial singer’s pitch get into the song.
9. Adjust Flex Tune
When Flex Tune is set to zero, it allows the application to tune every moment of the vocal sound wave to lớn the nearest correct pitch.
When we set it khổng lồ a value greater than zero, it only corrects the sound which is in a certain proximity to the correct pitch. The greater the value, the closer khổng lồ the correct pitch the vocal should be lớn be corrected, the voice variations that are farther from the note than the phối value, will not be corrected.
So in practice, what this parameter does, it allows leaving the singer’s voice variations in approaching the chú ý in the song unchanged. We also can’t bởi without Flex Tune when we autotune a guitar track, because there are lots of sounds sliding up & down the pitch in a guitar part, and we want lớn preserve that.
9. Phối up Natural Vibrato knob
This parameter is initially set to zero. If we move it in the positive direction, it will amplify the vibrations in the vocal, if we move it in the negative direction, it will smoothen the vocal.
10. Use Humanize
This setting helps you lớn reduce the robotic effect of Auto-Tune even more. It is useful when you are using small Retune speed values, then Humanize will decrease the retune tốc độ for longer sounds making them more natural, & leave quick retune tốc độ for short sounds.
11. Use Create vibrato for special effects
This is a whole bunch of parameters for creating vibration in your voice that wasn’t present there. If you’d lượt thích to hear how this function is used in production projects, you can hear some of it in Post Malone’s songs.
The parameters in the “create vibrato” group specify it even more, where “shape” lets us choose the type of vibrato, “rate” specifies its speed, “onset delay” shows the time in milliseconds from the beginning of the chú ý to the vibrato, “onset rate” shows the timespan in milliseconds from starting the vibrato lớn its highest point, “variation” is a random diversity in the vibrato that humanizes it. “Pitch amount”, “Amplitude amount” and “Format amount” specify the vibrato even further.
12. Choose your scale at The Edit Scale Display in Advanced mode
As we said earlier, you can manipulate the scale parameters by choosing the chromatic scale option at the đứng top of the app’s window plus pressing the advanced mode. In this case, you’ll see an active keyboard that will visualize your scale choice. The notes in the vocal will be also shown on the keyboard while playing the song.
At the same time, there are also options in the advanced screen to lớn choose a major or minor scale. Most importantly, here we can work with each key separately using “Bypass” and “Remove” functions.
Bypass & Remove. If you press “Bypass” for a note, the pitch that would have been tuned to match this lưu ý will be left unedited. Activating “Remove” for a chú ý will delete this cảnh báo from your scale, so the pitch will be tuned lớn the next closest note.
You can use these two switches lớn create your own scale and cảnh báo selection for autotuning in various ways.
Applying “Bypass” & “Remove” can be useful, for example, in the following cases:
• A few off-tune notes. Maybe you don’t need to lớn correct every sound in the song, just a couple of off-tune notes. In this case, you can bypass the whole chromatic scale except for these two notes that need correction.
• Removing an extra chú ý from scale. In another case, you may remove a cảnh báo because you’d lượt thích AutoTune to lớn tune the voice to lớn another note and this one is just standing in the way.
• Building a custom scale. You want lớn create a scale with just a few notes that are far apart to get a more expressive Auto-Tune effect
• địa chỉ an extra lưu ý to the scale. Maybe the vocal must sing a note that is absent in the song’s main scale. Then you can deactivate the “remove” button for this note, & this way you are adding the chú ý to the scale, và it will be used in the autotuning.
There are other cases. For example, if you are not professional & not sure what the song’s scale is, be not afraid lớn use these advanced options, experiment with the switches, adding the notes that you need, và removing extra notes.
Use a keyboard edit switch remove/bypass khổng lồ the left of the keyboard to remove or bypass certain notes using the virtual keyboard
How lớn use Auto-Tune: TIPS
Auto-Tune is a complicated algorithm, and its effect may differ depending on the individual vocal qualities and singing style.
Tip #1
If you are planning lớn use Auto-Tune for your song, especially its robotic effects, the main rule is to listen lớn it during the recording.
The singer chooses how to lớn use Auto-Tune depending on the characteristics of the computer that is used and personal preferences. The singer can listen to lớn the autotuned sound live in their headphones or right after the recording process. Checking the result is crucial especially for receiving a heavy Auto-Tune effect because you can not predict how the autotuned track will look like. There may appear unwanted effects or sounds, và the singer will need khổng lồ redo the recording in such a way that will produce the desired sound with Auto-Tune applied.
As Auto-Tune corrects you, in case you can not hear what note you are singing, you may wander farther off-tune as the tuy vậy goes on. That’s why, when you are singing and listening to the autotuned version of the sound simultaneously in your headphones, it might be useful khổng lồ leave one headphone off your ear so you could hear the natural pitch of your voice as well.
Tip #2
When choosing the scale in the beginning, choose the chromatic scale at the top of the window, & the advanced view mode.
When you choose “chromatic” for scale at the top và advanced view mode, the keyboard at the bottom of the window gets activated. And you will be able khổng lồ enjoy all the benefits of the Edit Scale Display we described earlier in this article. You’ll have the option of choosing a major or minor scale again, & the opportunity to “bypass” or “remove” for every note.
Every voice and singing style is different, so it takes some time at first to learn how to lớn use Auto-Tune, and what settings should be applied for different songs. With experience, you’ll have more insight, but still, for every song, you’ll have to experiment a little và play with the settings listening to different variants of corrected audio until you choose the final version.
