The use of partial update adaptive filters for stereophonic acoustic echo cancellation is investigated. The MMax-NLMS algorithm is studied in this context and its inherent robustness to subsampling of the tap-input vector is demonstrated. It is proposed to employ the subsampling of the tap input vector, that is intrinsic to partial update schemes, to decorrelate the two tap-input vectors of the...

Wave Field Synthesis (WFS) is a sound reproduction technique using loudspeaker arrays that postpones the limits set by conventional techniques (stereo, 5.1 ...). These techniques rely on stereophonic principles allowing the creation of an acoustical illusion (as opposed to an optical illusion) over a very small area in the center of the loudspeaker setup, generally referred to as “sweet spot”. ...
