Abstract
Techniques of delivering audio in a telepresence system include specifying a frequency threshold below which crosstalk cancellation (CC) is used and above which VBAP is used. In some implementations, such a frequency threshold is between 1000 Hz and 2000 Hz. Moreover, in some implementations, the improved techniques include modifying VBAP for more than three loudspeakers by forming an over-determined system to determine the amplitude weights for all loudspeakers at once.
