Virtual space in recordings

[out...@city-net.com]

The current online stereophile mag has a discussion of products offered by
naxos. There is one which addresses some recent threads about having the
media holding the music contain information that directs a home system to
best reproduce various performance venue information. The ideal system
would respond to that media contained information in the same way it was
heard when being performed. Here is one example which sort of
approximates that idea in some ways. The multiple instruments refers to
multiple recordings of the same piece on different instruments.

This collaboration between Naxos and McGill University's Centre for
Interdisciplinary Research in Music Media and Technology allows audio
playback in both 5.0-channel surround (DTS-HD) and hi-rez two-channel PCM.
In the most novel feature of the Blu-ray videodisc, which contains three
hours of HD video, viewers can shift Beghin's performances among nine
"virtual rooms," each an aural replica of an actual room in which Haydn
and other keyboard players of his era would have performed. viewers can
switch among the seven instruments, for a total of 63 (9 times 7) possible
combinations.
