Surroundizer offers stereo to surround translation.

Common features:

  • Activation and free 2D position of up to eight loudspeakers, compatible with all surround settings from 4.0 to 7.1, including true octophony (8.0).
  • Mono or stereo input.
  • Graphic 2D representation space.
  • Connexions according to the ITU/SMPTE standard.
  • Separated levels for each output channel.
  • Variable mix of the three sections plus the reverberation.
  • Individual spatial areas and amplitude curves for each section.

Three spatialization sections: Cinetic, Spectral and "LCRS".

Cinetic section:

  • Analysis of the main frequency (pitch tracker) and the intensity (volume tracker) of the two input channels.
  • Modulation of the X/Y position of the two inputs according to the analyzed signal values.
  • Settings for the default center position, the amplitude of the movement and the smoothness.
  • Each channel tracker can control the X or Y position of the two inputs.
  • Manual mode for use like any surround module and host automations.

Spectral section:

  • Division of the two inputs signals in four frequency bands with three variable crossover filters.
  • Each frequency band can be freely positioned (and automated) inside the 2D space.
  • Levels settings for each band / channel.


  • Simulation of the old Prologic surround sound (5 channels only).


  • Stereo reverberation with spatial position of the two channels and the area expansion.
  • Individual delay and phase settings for the four surround channels (5 to 8).
  • Two parametric filters for the center channel (must be improved).
  • Optional bass management for the fourth channel.
  • Pre-assigned MIDI controllers for easy use with a control surface.
  • 128 patches.
  • Inline help.

The freeware version is limited to processing only one input.
