Free Audio Plugins & Softwares for Windows

Duet

Duet is a free harmonizer VST plugin developed by Martin Eastwood Audio. Compatible OS(s): Windows.

Duet is a double-tracking/harmonizer effect developed to enhance vocals and instruments by thickening the sound and adding a rich glossy sheen to the audio material.

Duet works by independently pitch-shifting the left and right inputs allowing pitch to be manipulated in real-time, while still maintaining the time duration of the audio. By also delaying the re-pitched audio and altering its pan position, Duet can accurately create the illusion of multiple voices and add a luscious texture to your music.

Duet can also be used to create a silky chorus effect through modulation of the pitch-shift amount and to add movement and texture to synths.

Duet is available exclusively on Computer Music Magazine’s cover DVD each month.

Dualism

Dualism is a free studio tools VST plugin developed by Ugo. Compatible OS(s): Windows.

Dualism is a plugin version of the dual arpeggiators and 2X MIDI utilities found within M-theory and, as such, provides you with the ability to arpeggiate/double any other synth you wish, including hardware synths.

Combining two flexible and programmable phrase arpeggiators with a pitch and speed controllable MIDI doubler, Dualism allows you to create arpeggiations that are far more complex and detailed than your standard synth arpeggiator. However, all this flexibility is contained within a small and straightforward interface, letting you quickly and comfortably create complex patterns without having to feel slowed down but the UI.

Dualism is bundled with M-theory.

Key Features:

Dual programmable phrase arpeggiators.

Multiple playback options.

Pattern length adjustment for each arp.

Latch and arp bypass modes.

2X MIDI note doubler.
