Good Side

Bad Side

Disclosure: When you buy through our links, we may get a commission at zero cost to you.

Little AlterBoy is a Voice manipulation tool by SoundToys, it comes bundled with several features to transform the pitch of a voice, or change the singer’s gender with formant shifting.

Also, you can lock onto a single pitch for robotic sounds. You can even control the vocal’s melody using MIDI for creative vocoder-like effects.

Note: Little AlterBoy is designed to process only clean monophonic vocal tracks (much like some other vocal tuning plug-ins). Please experiment away, no hard rules in music production

I’ll let you on a little secret — The Little Alterboy was the plugin I used to create Exclusivemusicplus signature tag, here is a before and after:


After (Added Little Alterboy plus tweaking the pitch knob):

The Pitch and Formant

Little Alterboy Pitch and formant

The PITCH knob allows you to alter the pitch of your vocal track in semitones up to an entire octave above or below the original. For example, turning the Pitch control all the way counter-clockwise to -12.0 will shift the vocal down by one whole octave, which is what I did with the above demo

The FORMANT knob allows you to control the speeding up or slowing down of a sample. When LINK is OFF, the pitch-shifted vocals will be more natural- sounding, and also allows FORMANT to be adjusted independently of PITCH.

Tip: To get DJ-style pitch warping, leave LINK set to ON. Also, this mode will sometimes produce smoother results, especially for more challenging vocal tracks or pitched instrument tracks.

Little Alterboy Mode & Drive

It features three modes, Transpose, Quantize, and Robot:

  • The Transpose is the normal operation mode, the pitch control will simply shift the pitch of the incoming vocal without automatic correction.
  • The Quantize tunes your vocal to the nearest chromatic semitone as quickly as possible. This would result in an automatic tuning effect found on popular pop/rap/ R&B tracks.
  • Robot locks your vocal track to a single note. The specific pitch is controlled using the PITCH knob.

Tip: In ROBOT mode, when the PITCH knob is set to 0.0 the vocal pitch will be locked one octave above middle C. To produce notes other than “C”, simply adjust the PITCH control.

The Drive knob is a classic tube saturation model from Soundtoy’s plugin (Decapitator), it adds warmth and edge to your new vocal creation.

Control Your Creation

Once you’ve crafted your perfect vocal effect signature, you can use MIDI in your DAW to control the pitch for dramatic vocoder or harmony effects. It’s a hugely powerful way to find new directions and drive new ideas.

History in the Re-Making – How SoundToys Created Little AlterBoy

Our roots are in pitch-shifting. Our founders were part of the team that created the Eventide H3000, one of the most iconic pitch-shifters of all time. They went on to start a company called Wave Mechanics (soon to be called Soundtoys), which created the first real-time pitch and formant shifter: PurePitch TDM. Back in the ProTools TDM years, SoundToys also produced other high-quality pitch-based effects including the acclaimed PitchDoctor and SoundBlender.

With Little AlterBoy, we’ve distilled all of that knowledge to create a potent little vocal tool. We wanted to give you a wide range of the most popular vocal effects of the day, and give you the freedom to create your own signature sounds, too.
