Let
denote the number of virtual acoustic sources and let
be
the number of speakers. Then in PBAP, the
th speaker signal is
given by a sum of delayed source signals:
![$\displaystyle s_j(n) = \sum_{i=1}^{N_s} x_i(n-D_{ij}), \quad j=1,2,\ldots,N$](img47.png) |
(4) |
where
is the
th source signal, and
is the
time-delay, in samples, from virtual source
to speaker
. The
signal
is obtained as the output of a fractional-delay
filter driven by
. The same delay line can be used for source
to all
speakers, using ``taps'' to interpolate
(Smith et al., 2002).
