Single-channel hands-free teleconferencing structures have gotten well known. with a view to increase the conversation caliber of those structures, an increasing number of stereophonic sound units with loudspeakers and microphones are deployed. end result of the coupling among loudspeakers and microphones, there is robust echoes, which make real-time communique very tricky. the way in which we all know to cancel those echoes is through a stereo acoustic echo canceller (SAEC), which might be modelled as a two-input/two-output procedure with actual 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 commonly linear version. From this new handy formula, they re-derive crucial points of a SAEC, together with id of the echo paths with adaptive filters, double-talk detection, and suppression.
