An Advanced Implementation of a Digital Artificial Reveberator

Document Thumbnail

Reverberation is a well known effect particularly important for listening of recorded and live music. In this paper we propose a real implementation of an enhanced approach for digital artificial reverberator. Starting from a preliminary analysis of the mixing time, the selected impulse response is decomposed in the time domain considering the early and late reflections. Therefore, a short FIR is used to synthesize the first part of the impulse response, and a generalized recursive structure is used to synthesize the late reflections, exploiting a minimization criterion in the cepstral domain. Several results are reported taking into consideration different real impulse responses and comparing the results with those obtained with previous techniques in terms of computational complexity and reverberation quality.
