Matthias Becker has released Spartacus, a stereo enhancer based on the Orban A222 Stereo Spatial Enhancer. Instead of enhancing the whole signal, it only enhances the attack transients. This way you hear a wider sound without unnaturally exaggerated reverberation.
It has two controls:
- Amount: This controls the amount of spatial stereo enhancement (0% means no effect).
- Length: This determines the length of the transients.
Spartacus is available as a free VST effect plug-in for Windows.
