Spatifier is a mono to stereo spatial enhancer plugin designed for Windows and Mac OS X, available in AU, VST2, and VST3 formats. It transforms mono tracks into richly spatial stereo sounds, making it ideal for a wide range of instruments including clean and distorted guitars, synths, piano, organ, and backing vocals. Beyond enhancing individual tracks, Spatifier can also be used to thicken reverb sends and add depth to thin or flat audio sources.

The plugin works by decorrelating the signal between left and right channels while maintaining full mono compatibility. This process generates an expansive surround effect that can replace traditional double-tracking techniques, offering control over the spatial impression from upfront and direct to distant and reverberant. Users can tailor the spread and character of the stereo image to suit various mixing needs, enhancing overall soundstage and presence.

Spatifier achieves its unique effect through a sophisticated impulse response shaped by graphic equalizer-like controls, allowing precise adjustment of spatial effects across 16 individual frequency bands. This approach not only provides detailed control over the stereo enhancement but also adds warmth and richness to the processed sound. With features such as selectable random variations, zero latency processing, support for all sample rates, and a preset manager with undo/redo history, Spatifier offers a powerful and flexible tool for spatial enhancement in any production environment.
