In this Guru tutorial we look at setting up side-chain inputs on VST plugins using the excellent VocALign plugin from Synchroarts. VocALlign automates the often tedious manual process of aligning vocals. After setup, all it takes is just a single click. But wait there's more!
Sidechaining is an 'audio send' from the output of one mixer track directly into an effect plugin loaded somewhere on a second mixer track. Sidechaining allows plugins that can accept more than one audio input to process multiple independent audio streams, in addition to those passing through the mixer track where the effect is loaded. For example, VocALign can accept a single sidechain input to feed in the guide vocal, while Vocodex can accept a pair of sidechain inputs, one for the Modulator and one for the Carrier processing sections.
