Hybrid Reverb describes the combination of convolution reverb and a synthetic reverb structure to create artificial reverberation. This report describes recent methods in the field. An implementation of a hybrid reverberator is described, using state-of-the-art methods by combining convolution reverb for modelling early reflections and a filter structure for synthetic late reverb, whose coefficients are parameterized from room impulse responses, using Energy Decay Relief analysis and Least Squares optimization.\newline
The implementation is evaluated through signal comparison, a subjective listening test, and an objective evaluation of perceived audio quality. The goal of the evaluation was to find out if the implemented method performs better than a more rudimentary hybrid reverberation method. The results show only a marginal difference in favor for the implementation, while laying the foundation for future work and possible alternatives to the investigated structure.
