Classification of spatial sound reproduction technologies, by Philippe-Aubert Gauthier

Philippe-Aubert Gauthier has published a useful classification of spatial sound reproduction technologies, based on a large bibliography and some early feedback.

His top level categories of classification are the paradigm of sound field simulation, being either physics-based (eg wavefield synthesis), or perception-based (examples range from stereophony to synthesis of fundamental binaural cues).

The categorisation is nicely lateral in its thinking, for example, including exterior soundfield simulation that might be used to synthesis instrument directivity patterns (although this section neglects to mention O-Format, a method analogous to B-Format Ambisonics for representing outward facing directivity patterns using spherical harmonics). Another omitted technology is Vector Based Ampitude Panning (VBAP), for synthesising interior sound fields, though it might be hard to categorise into either physics-based or perception-based.

That said, this website offers a good introduction to a way of thinking about spatial sound reproduction that is more expansive than many information sources.

    Thanks for the post.

    I also received some critics regarding the total exclusion of spatial sound approach such as loudspeaker concerts in electroacoustic music, sound installation, etc. This is simply caused by the fact that I wanted to concentrate the classification on >>reproduction<< technologies which imply the fact that you are interested in approachin a target.

    Bye!
