Spatifier is a "mono to stereo" spatial enhancer plugin for Windows and Mac OS X in AU and VST2 / VST3 plugin formats.
This plugin can be effectively used to turn mono tracks into spatially-enhanced stereo tracks: it works for clean and distorted guitars, synth instruments, piano, organ, back vocals and other sounds. Beside that Spatifier can be used to "densify" the sound of reverb sends, and to add "body" to thin and flat sounds.
Spatifier decorrelates the signal in the left and right channels while retaining the "mono compatibility". Such decorrelation creates the "as wide as possible" surround effect. This effect can be usually used in place of double-tracking technique. The spatial impression can be adjusted in the range from the "in your face" direct to a distant reverby sound.
Spatifier achieves its result by first designing a complex impulse response that is then used by its internal convolution processor. The impulse response is defined by means of graphic equalizer-like controls (which can be adjusted in a freehand mode with the right mouse button). This makes it possible to set the spatial effect for each frequency band individually. In many practical cases Spatifier adds a great deal of warmness and enriches the timbre of the sound being processed.
