From reverberated audio signals and using as reference the input (anechoic) audio, a number of distortion maps are extracted indicating how room reverberation distorts in time-frequency scales, perceived features in the received signal. These maps are simplified to describe the monaural time-frequency / level distortions and the distortion of the spatial cues (i.e., inter-channel cues and coherence) which are very important for sound localization in a reverberant environment. Such maps here are studied as functions of room parameters (size, acoustics, distance, etc), as well as due to input signal properties. Overall perceptual distortion ratings are produced and reverberation-resilient signal features are extracted. These tests are also compared to results of subjective evaluation for the relevant features in the reverberant signals.
