Single-channel hands-free teleconferencing structures have gotten well known. so as to increase the communique caliber of those structures, progressively more stereophonic sound units with loudspeakers and microphones are deployed. a result of coupling among loudspeakers and microphones, there's powerful echoes, which make real-time communique very tough. 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 actual random variables. during this paintings, the authors recast this challenge right into a single-input/single-output approach with complicated random variables due to the generally linear version. From this new handy formula, they re-derive an important facets of a SAEC, together with identity of the echo paths with adaptive filters, double-talk detection, and suppression.
