HybridReverb2 is a convolution-based reverberation effect which combines the superior sound quality of a convolution reverb with the tuning capability of a feedback delay network. The sound quality of a convolution reverb depends on the quality of the used room impulse responses. HybridReverb2 comes with a set of room impulse responses which were synthesized with tinyAVE, an auralization software which was developed at the Institute of Communication Acoustics, Ruhr-UniversitÃ¤t Bochum (BorÃ and Martin, 2009; BorÃ, 2009a). These room impulse responses are designed for a speaker setup with two front and two rear speakers (BorÃ, 2009b). For a full surround sound effect, you will need two plugins, one plugin which uses a "front" preset for the front channels and a second plugin which uses the corresponding "rear" preset for the rear channels.
