Conclusions
(preliminary yet)
• The loudspeakers
are generally judged more natural than the headphones
• The frontal (single) stereo dipole is the
system providing the better result/effort
ratio: it works with a normal stereo system, it does not require a lot of computational power for running the
inverse filters in real time,
and is generally very natural and provides good localization
• Adding the second stereo dipole
gives some advantages, but generally
they are not worth the extra effort required (4-channels processing, etc.)
• The normal stereo gives very poor
localization, and the perceived spectrum
changes with the direction of the sound source, so the “colour” of the sound is not preserved
• It is very important to provide
a confortable user’s interface: large LCD screen, wireless mouse, comfortable seat, proper
lighting, thermohygrometric
confort.
