The use of multiple B-Format impulse responses for various source positions allows embedding of these focussed sources within the reverberant field. ...
Acoustic measurements were carried out using modern techniques and the response collected in both mono and B-Format at various source-receiver positions within the space. ...
However, in order to correctly reproduce only the early reflections and reverberation of the space, the direct sound and first reflection must be identified in the impulse responses. ...
