VBAP is an amplitude - panning method to position virtual sources in arbitrary 2-D or 3-D - loudspeaker setups. In amplitude panning the same sound signal is - applied to a number of loudspeakers with appropriate non-zero - amplitudes. With 2-D setups VBAP is a reformulation of the existing - pair-wise panning method. However, differing from earlier solutions - it can be generalized for 3-D loudspeaker setups as a triplet-wise - panning method. A sound signal is then applied to one, two, or three - loudspeakers simultaneously. VBAP has certain advantages compared to - earlier virtual source positioning methods in arbitrary - layouts. Previous methods either used all loudspeakers to produce - virtual sources, which results in some artefacts, or they used - loudspeaker triplets with a non-generalizable 2-D user interface. + This a library for Pure Data that provides objects for realtime Vector Base + Amplitude Panning. Vector Base Amplitude Panning (VBAP) is a method for + positioning virtual sources to arbitrary directions using a setup of multiple + loudspeakers. In VBAP the number of loudspeakers can be arbitrary, and they + can be positioned in an arbitrary 2-D or 3-D setups. VBAP produces virtual + sources that are as sharp as is possible with current loudspeaker + configuration and amplitude panning methods, since it uses at one time the + minimum number of loudspeakers needed, one, two, or three. + . + With 2-D setups VBAP is a reformulation of the existing pair-wise panning + method.

Directional coordinates used for this purpose - are the angle between a position vector and the median plane (θcc), - and the angle between a projection of a position vector to the median - plane and frontal direction (Φcc). The perceived θcc direction of a - virtual source coincides well with the VBAP panning direction when a - loudspeaker set is near the median plane. When the loudspeaker set is - moved towards a side of a listener, the perceived θcc direction is - biased towards the median plane. The perceived Φcc direction of an - amplitude-panned virtual source is individual and cannot be predicted - with any panning law. + The directional qualities of virtual sources generated with VBAP can be + stated as follows.
