Abstract
Reverberation Time (RT) estimation is of great importance in de-reverberation techniques and characterizing room acoustics. Estimating and updating the RT parameter of an enclosed environment could be carried out either continuously or discretely in the free-decaying regions of recorded reverberant signal. In this paper, we present a novel continuous sub-band-based RT estimation method which employs the general model for the Power Spectral Density (PSD) of the reverberant signal. The temporal envelope of the observed reverberant PSD in each sub-band is fitted to the temporal envelope of the proposed theoretical PSD of the reverberant signal to estimate the RT value. In Comparison to a well-known method for RT estimation, the proposed approach performs both more accurately and faster, so that it can be used in real-time applications for fast tracking of the RT value with high accuracy.
