TC Electronic Helicon VoiceDoubler
Live overdubbing in a rackmount unit

It takes skill, time and punch-ins to create a properly doubled vocal track in the studio and, until now, it was nearly impossible to accurately create the effect live. TC Electronic Helicon VoiceDoubler is a rackmount effects processor that creates up to four humanized overdubs from your voice - live! The presets range from overdubbed vocals that sound “tight and intimate” or “loose and lively” and what’s more, the doubled voices can be mixed through pristine emulations of classic detune, microshift and chorus effects. A full complement of editing parameters will allow you to shape and customize your doubling sound. With its timeless combination of natural and effected doubling, your live vocals can finally sound like the CD.

TC-Helicon’s experience in creating realistic harmony voices created from a single voice extends to the studio practice of doubling as well. Each additional voice that is created by VoiceDoubler has its own character in terms of the way its pitch approaches every note, how sustained pitch is handled and the time variations that are a natural result of humans singing together. There is even a level modulation effect where the voices can get louder and softer over the duration of each note to provide a little extra detail to our detail-hungry hearing. All of these, plus your voice of course, can convince the listener that the thick, rich layered effect was created by simultaneous human vocals.

TC designed the 50 factory presets so you never have to adjust anything if you prefer not to. They cover everything from a single voice closely, but not perfectly, singing along to four wildly modulated voices emulating a loose group shout. Also present are doubling presets based solely on the µMod effects so you can recreate earlier recordings. Of course once you make changes, there are 50 user locations in which to store your own presets.

There is an extensive set of editing parameters to allow you to sculpt your own virtual doubling voices. Because they are so wide ranging, you are able to create sounds that have less to do with doubling and more to do with special effect character sounds. As with many TC-Helicon products, there is a free downloadable editor available from Vysor for Mac and PC.

The 50 factory presets in TC Electronic Helicon VoiceDoubler feature its two linked processors: Overdub and µMod (micromod). The Overdub processor uses TC-Helicon’s unique algorithms to provide convincing pitch and time modulations. These emulate a recording session where you layer your voice in unison up to four times. The µMod processor recreates the legacy effects that were used previously to produce a doubling-type effect such as chorusing and detuning.
