Surroundizer is a free stereo imaging VST plugin developed by Acousmodules. Compatible OS(s): Windows.
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.
LCRS:
- Simulation of the old Prologic surround sound (5 channels only).
Plus:
- 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.
