Abstract : This paper presents a hybrid reverberation processor, i.e. a real-time audio signal processing unit that combines a convolution reverb for recreating the early reflections of a measured impulse response IR with a feedback delay network FDN for synthesizing the reverberation tail. The FDN is automatically adjusted so as to match the energy decay profile of the measured IR. Particular attention is given to the transition between the convolution section and the FDN in order to avoid audible artifacts. The proposed reverberation processor offers both computational efficiency and flexible perceptual control over the reverberation effect.
