The idea of a harmonising plug‑in might not be new — but how about one with multi‑channel support and up to 100 voices?

Whether built into your DAW of choice, or a third‑party offering, there are now plenty of plug‑ins that can create doubles and/or harmony effects from a single audio source, but Sound Particles’ new Density plug‑in has a number of interesting twists. First, its underlying engine is built on particles and granular synthesis (technologies which are used in some of Sound Particles’ other plug‑ins). Second, it offers three distinct operational modes, called Basic, Detune and Multipitch, each offering more features to the user than the previous one. Third, as well as being capable of the usual mono/stereo input and output, this plug‑in supports a whole range of multi‑channel audio input/output formats, including binaural, various ‘.1’ channel counts (including 5.1 and 7.1) and Ambisonics. So if you want your plug‑in‑generated sound layers to be placed and to move around in a spatial audio environment, this may well be the plug‑in for you.
