Surroundizer Free

Surroundizer Free is a lightweight audio plugin that provides stereo to surround spatialization effects. It offers support for activation and 2D position of up to eight loudspeakers (compatible with all surround settings from 4.0 to 7.1, including true octophonic sound 8.0), mono/stereo input, graphic 2D representation space, separated levels for each output channel, variable mix of three sections and reverberation effects, as well as individual spatial areas and amplitude curves for each section.

The audio plugin needs a VST host like energyXT or VSTHost in order to be installed on all Windows versions out there and make use of its capabilities.

The layout cannot be described as highly intuitive so you may need to invest some extra time in the tweaking process in order to get an idea about how to make the most out of the audio plugin’s capabilities.

A help manual is not comprised in the package which means that you are on your own when it comes to discovering how the plugin works. Only some tooltips are displayed at the bottom of the main window, if you hover the mouse cursor over a specific function.

Surroundizer Freeoffers offers you the possibility to make use of three spatialization sections namely Cinetic, Spectral, and LCRS. The first section helps you perform an analysis of the main frequency (pitch tracker) and intensity (volume tracker) of the two input channels, modulate the x/y position of two inputs based on the analyzed signal values, set the default center position, amplitude of the movement, and smoothness, and control the x/y position of two inputs of each channel tracker.

The second one is suitable for dividing two input signals in four frequency bands with three variable crossover filters, placing each frequency band to the desired area inside the 2D space, as well as adjusting the level of each band/channel.

The last section, LCSR, emulates the old Prologic surround sound (5 channels only), while featuring support for stereo reverberation, individual delay and phase settings, two parametric filters for the center channels, and pre-assigned MIDI controllers.

Surroundizer Free comes bundled with several handy and smart audio options for helping you tweak and enhance the sound. It is suitable especially for experienced users.
