ExperimentalScene has released version 0.0.1 of SpatialVerb VST, a room modeling reverb effect unit. It models the early impulse response by simulating the response of a room using raytracing. The late impulse response is provided by a feedback delay network (FDN) which prevents ringing. The user has control over the location of two source and two destination points, room width, room height, wall absorb, cutoff, and gain.
SpatialVerb is available for Windows as a VST Effect and costs $20.
