DMG Audio’s Multiplicity is a “shockingly powerful” multiband mastering processor

Presumably not inspired by the 1996 Michael Keaton sci-fi human self-duplication comedy of the same name, DMG Audio’s Multiplicity is designed to take precision mastering to a whole new level.

Potentially quite intimidating but also “shockingly powerful”, it features multiband compression, expansion, gating and dynamic EQ. It can be used to both repair and enhance signals, and all with what’s described as an unprecedented level of control.

The interface is designed to be minimalist yet informative, and the sound pristine. Check out the specs below and find out more and download a demo on the DMG Audio website. Multiplicity runs on PC and Mac in VST/AU/AAX formats and is available for £157.50 during its first month on sale, rising to £175 after that.
