Parameter definition¶

Coordinate system convention¶

• cartesian coordinate system
• can be defined as desired

Parameter describing a sound source¶

parameter	description	data format	range	initial state	unit	example	misc
num	numbers of sound sources	int		first argument of the external	NA	num 3
list-message #	position of the #th sound source, optional status	int float float (float)				0 0.63 0.68	in 3D case (a-dbap3d) a third float number accounts for the third dimension
gain_snd #	gain value of the #th sound source	float			linear	gain_sbd 0 0.5	# is 0 for the first sound source
db_snd #
radius_snd #

Parameter describing a virtual space¶

parameter	description	data format	range	initial state	unit	example	misc
falloff		float
radius		float

Parameter describing the position of loudspeakers¶

parameter	description	data format	range	initial state	unit	example	misc
speakers	sequential list, sets the position of the speakers	list				speakers 0.1 0.1 0.9 0.1 0.1 0.9 0.9 0.9	speakers x1 y1 x2 y2. If 3D case then: speakers x1 y1 z1 x2 y2 z2
