Yes, but that's the point - for off-centre listening
Are you sure? Here is what MAG wrote in
1992 (ref at end):
"This [Energy] theory is apt mainly at
frequencies between about 700 Hz and 5 kHz
for central listeners, but it can be shown that if
the sound arrivals from the n loudspeakers
are phase incoherent with one another (as
might be the case with very non-central
listening positions), then the velocity vector
theory gives the same predictions as the
energy vector theory, so that for such
listeners the energy vector theory is useful
even at frequencies well below 700 Hz."
This reads to me that for off-centre listeners,
Energy decoding is more useful than Velocity
decoding.
that's what i would have expected, too, but i've been wrong before.
peter, can you elaborate on your comment?
best,
jörn
