|Report About Blind Reverberation Time Estimation 1.0|
Matlab source code for blind reverberation time estimation from reverberant speech signals
The 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 in
Heinrich W. LdoTAllmann, Emre Yilmaz, Marco Jeub and Peter Vary:

The approach for a fast tracking of changing RTs by means of a second
histogram is not implemented in this version to further reduce the
complexity of the algorithm.The parameter setting for this program is not identical to the parameter setting used for the simulations examples in
the reference paper.
