Matlab source code for blind reverberation time estimation from reverberant speech signalsThe algorithm allows to estimate the reverberation time (RT or T60) within a range of 0.2s to 1.2s and assumes that source and receiver are not within the critical distance. A denoising is not performed by this function and has to be done in advance.The used algorithm is presented inHeinrich W. LdoTAllmann, Emre Yilmaz, Marco Jeub and Peter Vary:"An Improved Algorithm for Blind Reverberation Time Estimation"International Workshop on Acoustic Echo and Noise Control (IWAENC),Tel Aviv, Israel, August 2010.(reference avaiable at www.ind.rwth-aachen.de/~bib/loellmann10a)Note:The approach for a fast tracking of changing RTs by means of a secondhistogram is not implemented in this version to further reduce thecomplexity of the algorithm.The parameter setting for this program is not identical to the parameter setting used for the simulations examples inthe reference paper.
