If you happen to’ve by no means experimented with formant shifting, then that is the information for you.
Collectively, we’re going to take a look at:
- what formant shifting really is
- the way it works beneath the hood
- when to make use of formant shifting (and never simply on vocals
) - one of the best free and paid plugins to start out utilizing formant shifting in your tracks TODAY
Let’s get began! 
What’s Formant Shifting? 
Earlier than diving deeper into formant shifting, let’s first outline what formants are.
Harmonics and formants
A take a look at Wikipedia tells us {that a} formant is the “broad spectral most that outcomes from an acoustic resonance of the human vocal tract”.
Cool… that doesn’t inform us a lot 
. So what are formants in layman’s phrases?
The best way I like to consider formants is just like the idea of timbre. Timbre can be typically known as the tone “shade” or “high quality” of a sound. Mainly, it’s what makes the be aware D#4 sound completely different on a piano and a guitar. Each notes have the pitch, however they sound completely different. That’s timbre.
With out going into an excessive amount of music idea, this has to do with harmonics. Two devices enjoying the identical be aware can have the identical elementary frequency (let’s say 440 Hz for the be aware A4). Nevertheless, the variety of harmonics and their relative amplitude will probably be completely different.
Right here’s a fast instance:
Right here’s the frequency spectrum for the be aware A4 performed on a piano. We are able to clearly distinguish the basic at 440 Hz and the higher harmonics:
Right here’s the identical be aware, performed on a mandolin:
Clearly, we’re enjoying the identical be aware, however let’s take a look at the frequency spectrum of the mandolin:
Though the basic is identical, the harmonics are fully completely different. In a nutshell, that is timbre.
Formant shifting
You possibly can consider formant shifting because the timbre of a voice. Each a female and male voice can sing the be aware A4 – however they may sound drastically completely different. That is because of the quantity of harmonics and their relative quantity.
With formant shifting, we’re shifting the quantity of harmonics upward or downward. Nevertheless, the basic stays the identical.
The result’s a change within the tone of the vocal, with out altering the precise notes. Right here’s a fast instance:
The pitch stays the identical, however the high quality of the vocal has modified. In these examples, I used Little AlterBoy by Soundtoys (extra on that plugin later ):
Formant Shifting in Observe
Now that we all know what formant shifting is, let’s take a look at the best way to use it.
All formant shifting plugins can have a major knob that you may flip up or down.
Normally, this knob goes from -12 semitones to +12 semitones. Nevertheless, remember the fact that we aren’t altering the precise pitch right here:
Relying on the plugin you utilize, you may need extra controls similar to:
- Dry/Moist: controls how a lot of the processed vocal is combined with the unique vocal
- Width: provides stereo widening by detuning and panning two copies
- Extra superior plugins may need superior controls to mimic sure forms of vocal performances (soprano, tenor, and so on.)
When to Use Formant Shifting
So, when must you use formant shifting?
Properly, the obvious instance is to rework a pattern you discovered on-line.
We really devoted a full information to processing samples creatively. Everytime you obtain a pattern from Splice or Loopcloud, the objective ought to all the time be to make it your personal.
Nevertheless, there are a ton of different methods to make use of this cool impact. Let’s take a look
Artistic layering
You may also use formant shifting so as to add depth to your vocals.
This works particularly effectively on background vocals. However you may as well add a delicate layer on a lead vocal.
In case your vocal feels a bit too skinny, attempt including one or two layers. You possibly can for instance shift one layer up, and the opposite down.
One of the best to go about that is to make use of parallel processing. Primarily, you duplicate your vocal: one dry and one moist:
On our moist channel, you will set our formant shifting to 100% moist. We are able to then additional sculpt it with its personal EQ, compression, and reverb.
Delay… with a twist
All of us love a great delay on our vocals. However why not spice issues up with a little bit of formant shifting?
To do that, be sure your delay is about on a ship or parallel channel. Modify the formant shifting, and experiment with completely different delay instances.
Right here’s an instance with the next settings:
- Formant shifting at -7 semitones
- Delay set at 1/2 be aware
- Rolling off the lows with EQ
Real looking Autotuning
Do you generally have to pitch-correct a vocal efficiency? Then formant shifting will assist you get a extra pure tone.
It is because while you pitch a vocal up or down, you’re additionally transferring your entire harmonic content material. The result’s typically known as the “chipmunk” impact in case you go various semitones.
When this occurs, attempt adjusting with some downward formant shifting. It will assist you take away a few of the excessive harmonics that had been launched with the pitch shifting.
Artistic Makes use of of Formant Shifting
Lastly, you don’t have to limit your self to vocals!
Attempt including formant shifting on random devices and see what you provide you with.
I discover that automating this impact works nice for transitions. On this instance, I’m pitching down the formants of the drum loop. The impact is considerably just like a filter, however with an added twist:
