This package contains a Matlab reference implementation of a novel algorithm to estimate the direct-to-reverberant energy ratio (DRR) blindly from a dual-channel reverberant speech signal.

Within the Matlab script 'DRR_est_example.m', a speech signal is convolved with room impulse responses having various DRR values. The subsequent framewise DRR estimation procedure is illustrated over time showing also the true DRR obtained directly from the room impulse response.
