Abstract:
A method for eliminating acoustic reverberation in an audio signal. First and second level measurements are performed on the audio signal. The first level measurement uses a first attack parameter and a first decay parameter to measure a first attack time and a first decay time. The second level measurement uses a second attack parameter and a second decay parameter to form a second attack time that is identical to the first attack time and a second decay time that is longer than the first decay time. A difference between the first and second level measurements is calculated. The difference and the second level measurement are used to estimate a reverberation interference level, and the first level measurement and the reverberation interference level are used to ascertain a gain parameter for the audio signal.
