Spazial is a powerful audio processor VST plug-in designed to create wide stereo effects and is able to encode and divide the incoming stereo signal into M / S signals but also decode M / S signals into stereo signal.
“Spazial” uses different ways to processing the incoming signal.
There are 5 modes of using it : “internal”, “send mid”, “send side”, “spazial” and “decoder mode”.
“Spazial” allows the processing of the signals encoded by five potentiometers on the panel or sends the encoded pure signals directly to the output via the functions “enc mid” and “enc-side”. In the panel also has a very useful high-pass filter and a very special vibrato control.“Spazial” is free donationware and available in VST format for Windows.

SpatSurround 5M provides automatic spatial modulation of two inputs in 5.1 surround mode, a kind of five channels “super-autopan”.
The speed and shapes of X and Y axis curves can be set independently for non symmetrical complex modulations, and a third modulator allows to make evolving trajectories. The global movements can also be freely moved and scaled.
Like in the other AcousModules, the left and right input channels can be linked in several ways for true stereo spatialization, and the distance factor can be set for each speaker and channel.
Work inside Podium, Cubase SX, Nuendo, Tracktion within the racks, and all modular software.
