Perceptually Motivated Signal-Dependent Processing for Sound Reproduction in Reverberant Rooms

摘要

A perceptually motivated signal-dependent metric for modeling perceived alterations in audio signals caused by reverberation, the reverberation masking index (RMI), is proposed. Unlike existing descriptions and measures the proposed RMI is varying dynamically with each signal's evolution in a way that appears to be compliant to the perceived alterations in the reproduced audio. Furthermore a novel processing scheme to suppress reverberant cues in recorded audio signals is introduced, based on the RMI. Informal listening tests indicate the validity of the proposed signal-dependent processing framework.
