01Overview

Vocal Splitter is built to widen a mono vocal recording so it sounds fuller in a stereo mix. W. A. Production designed it around a processing technique that engineers have long used to help flat mono vocals stand out. Beyond vocals, the developer notes the plugin can also be used on other audio. The plugin includes Speed, Depth and Drive controls, a Mute Source button for send-style use, and a set of presets for quick starting points.

How Vocal Splitter Creates Stereo Width

Vocal Splitter combines two processes. The first is a phase-offset vibrato that splits the left and right channels by detuning them asymmetrically. The second is an asymmetrical rectification of the left and right signal, which the developer says creates a better defined stereo image.

The Speed and Depth dials control the vibrato, letting you move from subtle thickening to full doubling. The Drive dial adds grit and definition. According to W. A. Production, pushing Drive hard produces a saturation-like effect and pulls the stereo image back toward the center.

Mixing Controls and Filters

The central mix dial blends the dry source signal with the added stereo signal. Pressing Mute Source leaves only the processed audio, which is useful for soloing the effect or running the plugin on an effects bus.

The high pass and low pass filters limit the added stereo signal to a chosen frequency range. The developer advises this to avoid unwanted phasing in the low end. The bypass control is click and pop free, so A/B comparisons stay smooth.
