In the field of acoustic echo cancellation, it is well known that the amount of cancellation attainable in real-world systems is limited. Euphemistically this limitation has been referred to in the acoustic echo cancellation community as the “20 dB rule” [1]. This rule reflects the observation that, typically, one can obtain only about 20 to 30 dB of(More)
In the field of acoustic echo cancellation, it is well known that the amount of cancellation that can be obtained in real-world systems is limited. Euphemistically this has been referred to in the acoustic echo cancellation community as ”the 20 dB rule” [?]. This rule was formed from many real-world observations that one can typically obtain only about(More)
A novel perceptually transparent decorrelation method for stereo (and multichannel) echo cancellation (SAEC, MAEC) systems is described in this paper. It is based on combining a previously known phase modulation technique with a magnitude modulation component. The new method is more effective at decreasing correlation for frequencies below 1 kHz, a region(More)
