Extraction of Ambiance Information from Ordinary Recordings

Among well-known psychoacoustic principles that have hitherto remained inadequately exploited in home music reproduction is the Haas effect, in which a subjective integration limits the ability to distinguish delayed sounds. This, combined with a demonstrated ability to perceive directional aspects in the reverberation components of a sound field, make possible a kind of decoding using a delay arrangement that allows, in effect, these components to be extracted and presented by side loudspeakers in a listening room. Spatial incoherence accounts for a natural diffuse perception of the reverberation that does not disturb the directional feeling for the direct components projected from the front. Tests show this psychoacoustic reconstruction of acoustical ambiance from two-channel recordings to be the equal of that obtained from four-channel recordings.
