Best Live Vocal Effects Processor

If you are vocalist, amateur or professional you are probably familiar with strength issues that can appear when singing. There are many times including while recording in a studio or during performances when your singing will be off. Electronic vocal processors are devices that can help you with these problems. The core principle is that they take in the current signals and make the right adjustments for the best vocal results.

Increasing your vocal strength is only one of the features of a vocal processor. They are able to do much more than that to help you get that professional sound. Many vocal processors can create multiple-part harmonies and loops or add in some cool effects for obtaining the desired sound. The technology has come a long way as you can now have a virtual sound engineer and your backup singers nicely packed in a simple portable device. If getting your hands on a quality vocal processor sounds appealing to you, there are a few things to be aware of before you jump in and make the purchase.

1. Harmonies

The ability to add harmonies is important for any high-quality vocal processor. And to bring more convenience, some devices come with smart features that use guitar or instrument inputs to change the harmonies so that they fit the played chords and your singing note. This happens without the need for manual tweaking so if this is important to you, make sure you get a vocal processor that can do this.

2. Pitch Correction (AutoTune)

Some vocal processors have more advanced features for pitch correction and this effect can be very useful for those looking for a bit of discreet help with more difficult songs.

3. Vocal effects and looping

Not all vocal processors allow you to control a wide range of effects like compression, delay/reverb or EQ. Some are more basic when it comes to this and only offer core effects. If your music style is more experimental it’s probably recommended to look for more exotic voicings.

4. Input/Output

A basic XLR connection should suffice for most vocalists but others which sing and play guitar simultaneously will probably require dedicated outputs for guitar and vocals. In this way, you can rout the guitar separately to a guitar amp and at the same time deliver the vocals straight to the PA.

Now that you have a rough idea about what a vocal processor has to feature in order to satisfy your needs, let’s take a look at the best such devices on the market right now. These have been carefully picked and analyzed to provide the best value for the money.
