Hmm, just got round to looking at the Wittek/Thiele paper.
"Interesting" is right. I have the greatest of respect for both Helmut
and Gunther, but paper isn't really up to their normal, very high,
standards. Just two mentions of (higher order) Ambisonics and no
inclusion of it in the comparison table ( Table 1). No clear
indication of where the data for this "Comparison of
stereo/surround-format profiles" came from (proper studies, a guess,
references [1] and [9] ??) and, interestingly, Ambisonics (either POA
or HOA) isn't included where it would have shown up very well,
especially on the reproduction of elevation.
Some other interesting statements, for instance page 7, "Thus,
stationary-source elevation cannot practically be accomplished" -
which, as we know, is not so, _if_ you use soundfield reconstruction
techniques such as Ambisonics (or 3-D WFS, or Holophonics, or...) and
page 14 "One signal on more than two loudspeakers leads to coloration
and thus should be avoided" - just on _more than_ two speakers? That
should surely be "more than one".
Ah well, at least it would get a sufficient number of speakers into
people's homes to do Ambisonics with height with a re-jigging of their
positions ;-)
