VoxDoubler is presented as two separate Plug-Ins that focus on the two most common vocal doubling workflows.


Vocal performances lie at the very heart of a song. Doubling vocals is a really effective way of adding more contrast, drama and presence to the story of your song.


It’s therefore hard to imagine much of recorded popular music without the special quality that double-tracked vocals bring to a mix, either used over an entire track or just to help a chorus or key lyric connect with a listener.

Why VoxDoubler?

You want believable and natural sounding doubles but don’t have access to your vocalist, or the time required to:


Record extra takes in order to comp doubles

Transfer a lead take into an external editor, make copies of it and then manipulate the pitch and timing of them

Maybe you like the speed of using a classic stereo imager, chorus or harmonising effect, but aren’t so happy with the rather unnatural artefacts that can often occur?


Enter VoxDoubler. Bespoke designed to give you the best of these two approaches; ease of use, real-time processing and results that sound as lifelike as if the doubled parts were actually multi-tracked.


Saving you time, money and maintaining your creative flow.


“It sounds terrific and is so easy to use”

User Feedback


Generates two new mono voices and pans them to the left and right of the original vocal.


Great for:


Widening a mono performance, ranging from subtle enhancement to a stack of hard-panned voices

Or why not try:


Manually processing the new doubled voices separately, then mixing them back in parallel with the original


“This IS the best Vocal Doubler I've used so far. Very natural sounding even soloed!”

User Feedback


Generates a new stereo doubled voice and overlaps it with the original vocal.


Great for thickening a:


Mono performance, emulating the effect of singing the same part twice

Stereo group of voices by doubling each voice



Generate believable double and triple vocal tracks to create width, depth or add thickness

Humanise section to adjust the Timing and Pitch of the doubles relative to the original vocal

Depth control to push the new doubled voices deeper into the mix

Tone control to prevent sibilant doubles from becoming distracting, or to brighten those that are too muddy

Track/Aux mode allows you to apply the effect in place or, for more advanced control, mix it in parallel on an aux return

A more cost-effective alternative, both in terms of initial outlay and speed of use, than more complex and manual processes

Engineered for vocals, but try it on instruments too!
