Single-channel hands-free teleconferencing platforms have gotten renowned. with a view to improve the conversation caliber of those platforms, an increasing number of stereophonic sound units with loudspeakers and microphones are deployed. as a result of the coupling among loudspeakers and microphones, there is robust echoes, which make real-time communique very tough. the way we all know to cancel those echoes is through a stereo acoustic echo canceller (SAEC), that are 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 process with advanced random variables because of the commonly linear version. From this new handy formula, they re-derive crucial features of a SAEC, together with id of the echo paths with adaptive filters, double-talk detection, and suppression.
