Multiband Dynamics Plug-in
By Sam Inglis

DMG Audio Multiplicity

DMG's comprehensive multiband dynamics processor adds a whole workshop to your mastering toolkit!

Dave Gamble is not a plug-in developer who does things by halves. In fact, you could say he does things by whole numbers, and large ones at that. Products released under his DMG Audio banner typically sport large numbers of features, large numbers of user-adjustable parameters and large collections of presets. Whatever type of processing is on offer, you can be pretty sure that a DMG implementation of it will cover every conceivable use case, and plenty of use cases you can't conceive of.

The DMG Audio product line already includes comprehensive EQ and broadband dynamics plug-ins, and the latest addition straddles the line where the two meet. Multiplicity is designed to tackle any and every situation where dynamics processing needs to be triggered by, or applied to, just part of the frequency spectrum. To describe it as a multiband compressor would be like calling Amazon's Alexa a music player: Multiplicity can do multiband compression, but it can also perform dynamic equalisation, upwards and downwards expansion, transient shaping, de-essing and much more. (As far as I know it doesn't spy on you or collect data about your shopping habits, either.)

Eight By Three

Multiplicity is available in all the usual native formats for Mac OS and Windows, and is authorised using a downloadable licence key. The basic user interface is businesslike and, considering the amount of power it conceals, relatively unthreatening. The largest area is given over to a graphical display, which overlays a representation of each band's frequency range and activity against an animated spectrogram of the input signal. To the right of this are detailed input and output level meters and a handful of global controls, which include wet/dry mix and automatic gain compensation. The lower part of the interface, meanwhile, displays specific controls for the selected band.

Each instance of Multiplicity can host up to eight processing bands, and these are divided between three stages of processing, labelled Pre, Xover and Post. In essence, you can think of the Xover stage as a more-or-less conventional multiband compressor, with the Pre and Post stages applying dynamic equalisation either side of this. To put it another way, the bands in the Xover section divvy up the entire frequency spectrum for potential processing, while the Pre and Post sections allow you to target...
