Single-channel hands-free teleconferencing platforms have gotten well known. with the intention to improve the communique caliber of those structures, progressively more stereophonic sound units with loudspeakers and microphones are deployed. end result of the coupling among loudspeakers and microphones, there is powerful 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 are modelled as a two-input/two-output method with genuine 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 generally linear version. From this new handy formula, they re-derive crucial points of a SAEC, together with identity of the echo paths with adaptive filters, double-talk detection, and suppression.
