What is a Vocal Processor?

A vocal processor is an effects unit that will allow the user to add effects to their vocals when singing, there are many different makes of vocal processors all of which provide functions and settings to make singing live a less stressful experience.

A vocal processor is very similar to a guitar effects pedal, but instead of the guitarist using it to alter their tone and add different sounds from pedals such as reverb or delay, singers can use these small audio devices during live performances. The most common functions on a vocal processor are pitch correction along with harmonisation.

The right gear for live performances can make a big difference to the performance of any music artist.

Some of the best vocal processors will enable the singer’s mic to be interactive with the guitar so when a chord is played on the guitar the singer’s voice will be auto-tuned to correspond with the guitarist’s chord playing so you never sound out of tune when singing.

Harmonising is also a great feature of a vocal processor, this will add a harmonious voice to whatever you sing which can give a much fuller sound especially if you perform live with backing tracks in a duo for example.

Top Effect Capabilities


Doubling creates an effect that makes your voice sound “larger” in the mix. It’s an extremely popular effect in a wide variety of musical styles from Pop to Hip-Hop and everything in between.


Also known as Echo, delay repeats the input sound in various ways, from single “taps” to multiple panned asynchronous repeats. Often, a delay is mistaken for reverb in a song. It’s typical in a recording to use a small amount of both delay and reverb to create the desired spatial effect.


Short for Reverberation, reverb simulates an acoustic space like a concert hall or a bathroom. Typically, slower songs use longer reverb and faster songs use shorter reverb.


Some people know it as the Cher or T-Pain effect. We call it HardTune. It’s a very aggressive form of pitch correction that forces the voice to “jump” from one note to the next in an almost robotic way. The effect works the best when confined to a set scale, where the intervals between notes are more noticeable. To get the most out of the effect, you’ll need to adapt your singing style to help accentuate the way that your voice shifts from note to note. Try sliding between notes.

This vocal processor has it all providing top-quality effects for live singers to really make an impact at live gigs or performances. With next-generation harmony processing, effects, and tonal quality you can’t go wrong with the Voicelive 3 Extreme.
