AB  - Reverberation is a well-known effect that has an important role in our listening experience. Focusing on hybrid reverberator structures, an innovative structure for the approximation of stereo impulse responses considering low complexity filters is presented in this paper. More in detail, the conventional hybrid reverberator structure has been modified using also a tone correction filter for the emulation of high frequency air-absorbing effect and introducing a technique for the reproduction of the stereo perception. On this basis, the presented approach allows to obtain a better approximation of the impulse responses considering both time and frequency domain. Several results are reported considering different real impulse responses and comparing the results with previous techniques in terms of computational complexity and reverberation quality.
