Sound Guy has released the first version of ReSpatializer, a VST/Audio Unit plug-in that lets users test and alter panning, surround-sound and general spatialization. These elements are displayed in a simple graphical interface, where users can also tweak spreading, channel gain, and mute or solo selection. Processing options include low-frequency effect tools, synching to the host tempo, and output to as many as eight channels in formats such as Dolby, DTS and ITU. Simulated surround is created by converting full-scale spatializations into stereo or binaural mixes. ReSpatializer is a Universal Binary for Mac OS X 10.4 and costs $100.
