About This Dereverberation Business: A Method for Extracting Reverberation from Audio Signals

Document Thumbnail

There are many situations where the reverberation found in an audio signal is not appropriate for its final use and therefore we would like to have a means of altering the reverberation. Furthermore we would like to be able to modify this reverberation without having to directly measure the acoustic space in which it was recorded. In the present paper we describe a method for extracting the reverberant component from an audio signal. The method allows an estimate of the underlying dry signal to be derived. In addition, the reverberant component of the signal can be altered.
