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-Universität Bochum (Borß and Martin, 2009; Borß, 2009a). These room impulse responses are designed for a speaker setup with two front and two rear speakers (Borß, 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.

Free and open source plugin (GPL).
High quality room impulse responses (PCM, 48kHz, 24bit).
Rear channel impulse responses for a natural spatial envelopment.
Low latency (down to 64 samples).
Low CPU load.
Individual performance optimizer.
Intuitive and clearly arranged user interface.
Quick selection of presets via categories.
Tuning of room impulse responses:initial gap / length / pre-delayo, dry / wet / master gain, envelope (with increasing resolution for fine tuning the early reflections), timbre (equalizer with 1/3 octave resolution).
Editor for the preset database.
User specified impulse responses can also be used.
