International Conference on “Room acoustics: Design and science”
Conclusions
•The spatial informations have to
be accurately sampled, making it possible to store, analyze and preserve these
“3D acoustical photographies” of existing musical spaces for the posterity
•Many different kinds of
impulse-response measurements are required for different 3D auralization
methods: a proper set-up should include all different approaches
•Once the impulse responses are
stored in suitable multichannel formats, they become available for surround
productions with today technologies (ITU 5.1, 1st order Ambisonics) and
future, more advanced methods (high order Ambisonics, WFS, Ambiophonics)
•The only point which requires substantial
enhancements: sound sources used for IR measurements
