Single-channel hands-free teleconferencing platforms have gotten renowned. as a way to increase the conversation caliber of those structures, progressively more stereophonic sound units with loudspeakers and microphones are deployed. as a result of the coupling among loudspeakers and microphones, there's robust echoes, which make real-time verbal exchange 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 procedure 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 facets of a SAEC, together with identity of the echo paths with adaptive filters, double-talk detection, and suppression.
