Single-channel hands-free teleconferencing structures have gotten well known. in an effort to improve the verbal exchange caliber of those platforms, an increasing number of stereophonic sound units with loudspeakers and microphones are deployed. a result of coupling among loudspeakers and microphones, there is powerful echoes, which make real-time conversation very tough. the way in which we all know to cancel those echoes is through a stereo acoustic echo canceller (SAEC), that are modelled as a two-input/two-output approach with genuine random variables. during this paintings, the authors recast this challenge right into a single-input/single-output procedure with advanced random variables because of the generally linear version. From this new handy formula, they re-derive an important elements of a SAEC, together with id of the echo paths with adaptive filters, double-talk detection, and suppression.
